Objective This study examined the effect of using a variable-height staple construct containing three rows of staples with heights of 3.0, 3.5, and 4.0 mm (staple leg length, medial to lateral) versus standard three-row single-height staplers (with staple heights of either 3.5 or 4.8 mm) for pneumostasis in healthy porcine and canine lung parenchyma to determine whether a single stapler that uses variable staple heights could perform as well as, or better than, existing single-height stapling devices. The work presented here used healthy animal tissues, in lieu of diseased tissue, which is extremely difficult to obtain and quantify. Methods Briefly, fresh explanted porcine and canine trachea-lung blocs were used for all testing. Tissue thicknesses were measured with a custom-design spring-loaded caliper before stapling with control and test articles to ensure that the tissue was of “appropriate” thickness for the stapler size (staple height) selected (per manufacturer's instructions for use). All tissue measurements were comparable across each area of lung tested, and both test and control devices were fired into the same tissue thicknesses. After stapling, the lungs were submerged in water, insufflated, checked for air leaks at four discrete (increasing) pressures, and scored using a predetermined scale. Statistical analysis was performed for n = 26 (3.5-mm staples), n = 29 (4.8-mm staples), and n = 26 or 29 (paired to the standard group) for the variable-height stapler (3.0-, 3.5-, and 4.0-mm staples). Results The results demonstrated that the test article comprising three rows of variable-height staples provided comparable pneumostasis with the standard three-row single-height staplers (with staple heights of either 3.5 or 4.8 mm) under the test conditions described. Conclusions A novel test article containing three rows of staples with heights of 3.0, 3.5, and 4.0 mm (variable-height stapler) showed promising results when compared with standard commercially available single-height staplers, performing as well as or better than the standard single-height staplers. This work demonstrates important first steps to proving equivalent device performance, which might facilitate the use of a variable-height stapler in place of multiple single-height staplers.

Full textAbstract:
Background: Laparoscopic appendectomy is the gold standard for treatment of appendicitis. Stapled closure of the appendiceal stump is commonly performed and has several advantages. Few prior cases have demonstrated complications from free staples left within the abdomen after the stapler has been fired.Case report: A 29-year-old female underwent laparoscopic appendectomy for acute uncomplicated appendicitis during which the appendix and mesoappendix were divided using laparoscopic gastrointestinal anastomosis (GIA) staplers. Her initial recovery was uncomplicated. She returned on postoperative day 17 with sharp mid-abdominal pain, obstipation, and emesis. Her abdomen was distended, and she had a mild leukocytosis. Computed tomography (CT) demonstrated twisted loops of dilated small bowel in the right lower quadrant with two transition points, suggestive of internal hernia with closed loop bowel obstruction. Diagnostic laparoscopy was performed through the three prior appendectomy incisions. An adhesion between the Veil of Treves and the mesentery of the ileum caused by a solitary free closed staple, remote from the staple lines, had caused an internal hernia. The hernia was reduced, and the small bowel was noted to have early ischemic discoloration. The adhesion was lysed by removing the staple from both structures. The compromised loops of bowel began to show peristaltic movement and color returned to normal, and the procedure was concluded without resection. She was discharged home the following day.Conclusions: Gastrointestinal staplers are commonly used due to ease of use and low complication rate. It is not uncommon to leave free staples in the abdomen as retrieval can be difficult and time consuming. Our case is only the second in the literature reporting an internal hernia with closed loop bowel obstruction as a complication of retained staples. Choosing the most appropriate size staple load to reduce the number of extra staples, removing free staples, or the use of an endoloop can prevent potentially devastating complications.

Use of the scanning electron microscope (SEM) for examination of tool marks, paricularly firing pin impressions of semi-automatic pistols, selected shotguns and rifles, is well documented. It was the intent of this investigation to apply SEM to staplers, in order to examine if the impressions on the shoe-ends of staples using a particular stapler possessed persisting defects with repeated tackings, and whether these defects can be used as “individual characteristics” in order to be able to identify the source of a staple on tacked papers from a list of eight staplers of different makes and models (Swingline® 747 and 27, ASCO® 40 and ACE® 102). The effects of pre-existing marks, which are usually existent as parallel striations on staples, and the different forms (100% round, 100% round with sharp points and chisel points) of staples on the resulting impression were examined by using different brands of staples (Swingline® standard No. S.F.-1, Swingline® R. W.-35, Bostitch® standard, and ACE® 2025).

Full textAbstract:
A small Zenker's pouch is a major challenge for endoscopic staple-assisted esophagodiverticulostomy (ESED). This study tested the stapler dimensions so as to identify limitations they impose on ESED. Combining ESED with additional endoscopic suturing could extend the incision and consequently the myotomy. Zenker's diverticulum residual pouch measurements were performed with a previously reported latex glove model and in patients undergoing surgery. Two stapler designs were compared by measuring the residual pouch length for both the stock and modified staplers. One other stapler model cannot be modified without damaging the mechanism. The Endostitch was used to place an additional suture at the apex of the staple line, allowing cutting between the staples while leaving a closed distal incision. All three staplers suitable for ESED leave a residual pouch of 1.5 cm when unmodified. The modified anvil staplers gave a smaller residual pouch by 4 to 5 mm. An additional septal reduction can be accomplished by suturing the area distal to the staple line and incising the party wall beyond the stapler cut. The absolute amount of residual pouch with an additional myotomy is 3 mm. The combined staple-suture technique has proven relatively safe thus far. To provide a maximally efficient myotomy in a patient with a short pouch, the surgeon needs to be aware of the stapler differences. Modifications of the staplers may decrease the depth of the residual pouch, but may carry an added liability. A minimum residual pouch can be achieved with a combination of stapler and suture techniques, but is more technically demanding than the original ESED description.

Background: The objectives of the study were to study the operative time, the effect on wound healing, cosmetic results, patients acceptance and total cost with the use of sutures and staples.Methods: The study was conducted on 100 patients who were undergoing elective surgery from January 2016 to July 2017 in our institute. The patients were randomly selected to receive either suture or staple.Results: The study group included 50 patients who underwent wound closure by staplers and 50 patients underwent suturing. The commonest region of the surgical wounds was Mc Burneys site. The time taken for wound closure using staplers showed statistically significance difference over closure with suture, it took the stapler 4 times less duration to perform wound closure. The average cost of using stapler was higher than suturing. The appearance of the scar among the staple group was good in 90% of those who returned for follow-up at 1 month, 10% had average scar. The patients acceptance was better in staple group with less pain during removal as compared to suture group. P-value calculated using students unpaired T-test. P<0.0001 which was highly significant.Conclusions: Staples did not cause excess wound pain and allows saving in time with better cosmetic results.

Objective: Healing of laparotomy wounds is associated with number of factors. The aim of the study was to compare skin stapler and polypropylene sutures in closing laparotomy wounds. Materials and method: This randomized controlled trial study was conducted at the Department of Surgery, Sir Salimullah Medical College Mitford Hospital, Dhaka, Bangladesh. The study duration was 6 months, from July 2010 to December 2010. A total of 100 participants were included in the study, divide in two equal groups of 50 participants. The first group received interrupted suture with 2/0 polypropylene. The other group received skin staples. Results: The mean time for closure with suture and staple were 3.7±SD and 22.5±SD cm/min respectively (p- value<0.05). Rate of wound closure was calculated in cm per minute and materials were compared statistically in pairs by t- test. Wounds were closed five times faster with staples then suture (p<0.001). In relation to post-operative infection, 17 (34%) cases developed wound infection in sutured group and 15 (30%) patients in stapled group. Most of the infection occurred in the emergency contaminated cases. There was no significant association between wound infections and method of skin closure (p> 0.05, chi square= 3.15). Conclusions: Staples were well-liked by operators and resulted in substantial and worthwhile savings in time for wound closure.

Full textAbstract:
Shape memory alloy (SMA) staples in nickel titanium with shape memory effect are effective for spinal growth control. This study was designed to evaluate the biomechanical properties of the staples and observe the stability of the fixed segments spine after the staples were implanted. According to the vertical distance of the vertebrae, SMA staples of 5, 6.5, and 8 mm were designed. The recovery stress of 24 SMA staples in three groups was measured. The pullout strength of SMA staples and stainless steel staples in each functional spinal unit was measured. Each of the six fresh specimens was divided into three conditions: normal, single staple, and double staples. Under each condition, the angle and torque of spinal movements in six directions were tested. Results show that the differences in recovery stress and maximum pullout strength between groups were statistically significant. In left and right bending, flextion, and extention, the stability of spine was decreased in conditions of single staple and double staples. Biomechanical function of SMA staples was superior to stainless steel staple. SMA staples have the function of hemiepiphyseal compression and kyphosis and scoliosis model of thoracic vertebrae in goat could be successfully created by the fusionless technique.

Full textAbstract:
Lack of reinforcements is an existing drawback of 3D printed cementitious components, which is an urgent concern. A staple-inserting apparatus was developed and installed on a 3D printer and automatically fabricated 3D printed and staple-reinforced components with 98% successful insertion to achieve inner- and inter-reinforcement of the printed strips. The inserted staples inside the printed strips improved the compressive strength by 25% maximum owing to the inner locking effect by the staple pins, while the flexural strength did not increase because the scattered staples functioned separately. The staples over the strip interfaces remarkably increased the flexural stress by 46–120%. The inserted staples demonstrated a significant strip locking effect, but the unavoidable voids decreased the bonding between staples and the composite. The mechanical analysis concluded that the printing parameters considerably affected the reinforcing rate. The staple inserting technique proved the feasibility of automatic fabrication of fiber-reinforced and printed concrete structures.

We reviewed the use of compression staples made of the memory metal alloy nitinol for fixation in foot surgery. A retrospective study was performed of 31 feet in 27 patients who underwent arthrodesis or an osteotomy fixated using compression staples. OSStaples (BME, San Antonio, Texas) were used in 18 feet, and Memodyn staples (Telos Medical, Fallston, Maryland) were used in 13 feet. A total of 48 compression staples were implanted. The following procedures were performed and fixated using compression staples: 15 Akin osteotomies, 2 first metatarsal base epiphysiodeses, 3 first metatarsal–cuneiform fusions, 2 naviculocuneiform fusions, 3 calcaneocuboid fusions, 4 talonavicular fusions, 3 subtalar joint fusions, and 2 Evans osteotomies. In our clinical experience, compression staples provide an adequate source of internal fixation in foot surgery. Good bone apposition and stabilization and compression of the bone surfaces before staple fixation are important when using staple fixation to promote an optimal environment for bone healing.

Limb asymmetry can, and often does, cause various health problems. Blount bone staples (clips) are used to correct such uneven growth. This article analyzes the performance of a biomechanical staple during bone (tibia) growth arrest. The staples considered in this study were made of 1.4441 stainless steel, the model of tibia consisted of two materials representing corticalis and spongiosis. Hooke’s law was used for modeling materials’ behaviors for finite element analysis (FEA). The maxima of stress and total staple displacement were evaluated using the finite element method and verification of the results, along with the determination of the maximum loading (growing) force that the staples are capable of withstanding, was performed experimentally. The presented method can be used to determine the safety and usability of staples for bone growth arrest. According to our results, the design of Blount staples considered in this paper is safe and suitable for orthopedic treatment.

It is very frequent that solid wood beams need to be connected one to another to obtain a longer beam. In this study, the behavior of solid wood beams connections using plywood sheets as connecting elements and staples as mechanical fasteners were studied experimentally. The experimental results were compared with elastic analyses. Both beam and plywood were made of meranti (shorea). The staple type was MAX 1022J. This study was conducted on two specimens. The first specimen had two rows of staples on the front and back sides of the specimen. Each row consisted of ten staples making a total of 40 staples. The second one had three rows of staples on the front and back sides of the specimen. Each row consisted of ten staples making a total of 60 staples. From the tests, it can be concluded that each material in the connection, namely wood beam, plywood, and staples, failed. Failure mode of the wood beam was in the form of crack and tear. Failure mode of the plywood was the damage of the plywood directly contacted with the crown of the staples. Failure modes of the staples were flexural yielding. The differences between connection strength obtained from tests and elastic analyses were 8.18% for the first specimen and 0.65% for the second specimen, with the test results were higher than the elastic analyses results. It can be concluded that elastic analysis is quite accurate and conservative to estimate the strength of this type of connection, provided that the lateral resistance of connection with a staple is known.

Full textAbstract:
The technique of aorta-coronary shunting offered by Dr. M. Soutorine by means of the original stapler developed by "Endogene" allows suturing blood vessels by superelastic Тi-Ni staples on «working heart» (without heart switching-off). The material for staples is a 0.30 and 0.315 mm diam. wire which was studied by DSC, shape recovery and mechanical tests. Thermomechanical treatment (TMT) comprised warm drawing, low- temperature (LTMT) by cold drawing with 25-30% strain in the last pass and following post-deformation annealing (PDA). LTMT leads to increasing of yield stress in comparison with warm drawing. Treatment of wire under LTMT+PDA allows obtaining the highest characteristics of functional properties of the wire. The difference between “dislocation” and “transformation” yield stresses Δ=900 MPa. Critical stress of superelastic recovery after TMT on the average is 1.5-2 times higher in comparison with warm drawing. The maximum completely recoverable strain r,1max=6.5%. The maximum obtained force value of staples is РrSE=6.5 Н. The shape recovery rate of staples was 85-97 % that provided its functionality. Storage in the stapler in straightened condition within 1 month does not worse the staples.

Introduction: Hemorrhoidal disease is the most common proctologic condition in adults. Among the different surgical procedures, one of the greatest innovations is represented by the stapled hemorrhoidopexy. The history of this technique started with a single stapler use passing through a double stapler technique to resect the adequate amount of prolapse, finally coming to the use of high volume devices. Methods: Nevertheless, each device has its own specific feature, the stapler is basically made up with one or more circular lines of titanium staples whose height may be variable. The procedure is based on different steps: Introduction of the CAD, evaluation of the prolapse, fashioning purse string or parachute suture, the introduction of the stapler head beyond the suture, pull the wires through the window, close the stapler and keep pulled the wires of the suture held together with forceps, fire using two hands, open the stapler and remove it and check the staple line and then check the specimen. One of the latest innovations in stapled surgery is Tissue Selective Therapy. It is a minimally invasive procedure in which there is a partial circular stapled hemorrhoidopexy focused on the prolapsing piles with bridges of normal mucosa left. Results: Several studies have reported that SH is a safe and effective procedure to treat hemorrhoidal prolapse. It is a quicker procedure with a shorter hospital stay and earlier return to work if compared with the conventional treatment. This is due to less postoperative pain, postoperative bleeding, wound complications and constipation. Furthermore, the first generation devices had worse outcomes if compared with those of the new generation stapler that showed lower postoperative complication rates with better anatomical and symptomatic results. Conclusions: Stapled procedure for the treatment of symptomatic hemorrhoidal prolapse represents one of the most important innovations in proctology of the last century bringing with it the new revolutionary concept of the rectal intussusception as a determining factor involved in the natural history of the disease. Stapled hemorrhoidopexy marked an era in which the surgeon may offer the patients a safe, effective treatment with less pain and fast recovery.

Background: The purpose of this study was to determine the radiographic union rate after midfoot and hindfoot arthrodeses using a new generation of nitinol staples, and to compare outcomes between a nitinol staple construct and a nitinol staple and threaded compression screw construct. Methods: A retrospective chart review was performed to identify patients who underwent hindfoot or midfoot arthrodesis using a new generation of nitinol compression staples with or without a partially threaded cannulated screw with minimum 3-month radiographic follow-up. The primary outcome variable was radiographic evidence of arthrodesis on radiographs and, when available, computed tomographic scan in patients who underwent midfoot or hindfoot arthrodesis using nitinol staples. Ninety-six patients and 149 joints were eligible for analysis. Median radiographic follow-up was 5.7 months. Results: Radiographic union was seen in 93.8% (60/64) of patients and 95.1% (98/103) of joints using the nitinol staple construct. Radiographic union was seen in 90.6% (29/32) of patients and 95.7% (44/46) of joints using the nitinol combined staple and screw construct. There was no significant difference in radiographic union rate or revision surgery between the 2 groups. Seven patients developed nonunion, 4 in the nitinol staple construct group and 3 in the staple and screw group. Conclusions: New-generation nitinol staples were safe and effective for hindfoot and midfoot arthrodeses, with a high radiographic union rate. The use of a partially threaded screw for additional fixation was not found to either significantly increase or decrease radiographic fusion with nitinol staple fixation. Level of Evidence: Level III, comparative cohort study.

Purpose. This study investigates the food expenditure path segmented by staples and non-staples in Nigeria.
Methodology / approach. A multi-stage sampling procedure was used to sample a cross sectional data of 438 urban households from two randomly selected urbanising states in South West, Nigeria. The study used descriptive statistics such as percentages and means to determine households’ food budget shares and their per capita food expenditure
Results. From the expenditure estimates, a differential effect in budget share of food was found with an increase in staples diet of Low Urban Area (LUA) households (33 %). However, consumption of non-staple foods was more pronounced among households residing in high urban areas (HUA) (35 %). Per capita food expenditure was higher for LUA households (N1377.52), while their food shares for processed cereals were equal with those of HUA. Findings suggest a more diverse diets, thus revealing a quality-quantity nexus within urban locations.
Originality / scientific novelty. This is the very study that explains urban differential beyond staple food consumption and nutritional outcome. The household food expenditure pattern brought to fore location-specific variations in urban diet in the study area.
Practical value / implications. The switch away from consumption of staples was beyond income responsiveness, but, towards changes in level of urbanization. The differential path in per capita expenditures on staple and non-staples are shown to have implications on nutrition within urban areas.

Full textAbstract:
Category: Trauma Introduction/Purpose: Ankle fractures are commonly treated fractures by orthopaedic surgeons with unique challenges to skin closure due to the lack of subcutaneous support. Metallic staples are a commonly accepted method of skin closure in other specialties, though the use of staples in orthopaedics, and more specifically in foot and ankle surgery, remains a topic of debate. Proponents of staples report several potential advantages to using staples instead of sutures, including reduced closure time, faster and less painful removal, or improved cosmetic appearance. This study aimed to compare outcomes of suture versus staple closure as well as to evaluate the safety of staple closure after open fixation of acute traumatic ankle fractures. Methods: The medical records of 94 patients treated at our institution with open fixation of an acute traumatic ankle fracture by a single surgeon between January 2011 and June 2017 were retrospectively reviewed. Demographics, preoperative characteristics, relevant comorbidities, operative characteristics, and postoperative outcomes were compared between patients who received superficial skin closure using staples versus suture techniques. Statistical analysis was performed using chi-squared test and Fisher’s exact test. Results: The staple and suture group patients were demographically similar at baseline. Of the 94 patients included in this study, 10 patients developed local wound related complications postoperatively, including 5 with wound dehiscence, 4 with superficial wound infections, and 1 deep infection . Eight patients required revision surgery due to infection or wound dehiscence. Four patients in the suture group developed superficial wound infections, compared with zero in the staple group. One patient in the staple group developed a deep infection. With the numbers available, no significant differences could be detected in the incidence of postoperative infections, local wound related complications and revision surgeries between two wound closure groups. Conclusion: Our data suggests that there is no statistical difference in outcomes between staple and suture closure after open fixation of acute ankle fractures. Because there was no difference in morbidity with possible benefits of reduced closure time, faster removal, and improved cosmetic appearance, we conclude that staple closure may be a safe alternative to sutures for superficial skin closure. This study adds evidence to a growing body of literature and suggests that staples can be used in some instances, clinical decision making, surgeon preference, and technique proficiency should remain the cornerstone of closure in ankle fracture surgery.

Background and Aims. Endoscopic fundoplication is an emerging technique for the treatment of gastroesophageal reflux disease (GERD). The aim of this study is to determine the ideal position of the staples in relation to gastroesophageal junction (GEJ).Methods. Ten endoscopic fundoplication procedures were performed in each group using fresh ex vivo porcine stomachs: Group A: 2 staples each at 3 cm above the GEJ and 180° apart; Group B: 2 staples at 3 cm and 90° apart; Group C: 2 staples at 4 cm and 180° apart; Group D: 3 staples at 3 cm with 90° between each staple (180° total). After the procedure, the stomach was gradually filled with water. Gastric yield pressure (GYP) was determined by detection of reflux of the water in esophagus or by rupture of staples.Results. Mean increase of GYPs (±SD) after the procedure was as follows: Group A:16.9±8.7; Group B:8.1±7.9; Group C:12.2±9.4; Group D:22.7±13.3. GYP in Group A and Group D was higher than Group B (p=0.03andp=0.01, resp.).Conclusions. We recommend the placement of 3 staples at 3 cm distance from the GEJ, which resulted in the highest increase of GYP.

The aim of this paper was to study the outcome of first MTPJ fusion surgery using fixation with orthogonal shape memory alloy (Nitinol) staples. Methods: 75 consecutive patients who underwent first MTPJ fusion with orthogonal memory staples were included in the study. All patients underwent surgery using standard surgical technique with fixation of the arthrodesis with two 20 mm shape memory alloy (Nitinol) staples (Memo staples, Ortho Solutions Inc). The first staple placed medially and the second staple placed dorsally in orthogonal plane. The arthrodesis surfaces were prepared and temporarily fixed with K wire. Once the position and bone approximation was confirmed satisfactory under image intensifier guidance, a flat staple bed was prepared with saw blade to make sure the staples are not proud after fixation. All patients also received standard postoperative care with heel weight bearing shoe for six weeks and follow-up at 3,6 and 12 weeks as standard regimen. Patient demography, time to clinical and radiological union, early/late complications, rate of non-union, revision surgery and implant removal were noted. Results: Average age was 64.6 years. 42 patients had severe radiologic arthritic changes while 27 patients had associated moderate to severe hallux valgus deformity. Five patients were known to have inflammatory arthritis. The average follow-up was 18.3 weeks. There were two early complication of superficial infection treated successfully with oral antibiotics. Average clinical union was 7.2 weeks and radiological union at 12 weeks. Five patients (6.6%) had radiological non-union of which four underwent revision surgery with plate fixation. One patient had delayed union while one had dorsal staple back-out but did not warrant removal. None required staple removal from hardware prominence. There was no significant difference in union or complication rates with regards to gender or presence inflammatory arthritis. Conclusion: This study demonstrates that the outcome of 1st MTPJ fusion with two memory staples in orthogonal position is comparable with other modalities of fixation in terms of rate of union and resurgery. It is safe, simple and easily reproducible technique. Besides, none of the patients in this series required implant removal for hardware related complications. This could be advantageous compared to fewer other modalities like plate fixation, though larger studies are needed to confirm it.

Aim: To evaluate the effect of Tri-staple™ technology and slow firing using the Endo-GIA™ endoscopic linear stapler. Methods: The cardiac and pyloric portions of porcine stomachs were divided using the endoscopic linear stapler with different reload types. A total of 8 min of waiting time was employed during firing in the slow-firing group and no waiting time was employed in the normal-firing group. The shape of the staples was then evaluated. The length of the staple line and serosal laceration was also determined. Results: There was a moderate negative correlation between tissue thickness and secure staple formation. Tri-staple™ reloads (purple, black) offered more secure staple formation compared with Universal green reload. Although slow firing enhanced secure staple formation, its effect was greater when using green reload, compared with Tri-staple™ reloads. Significantly shorter staple line length and longer serosal laceration was observed in the thick tissue. Although the cartridge type did not influence lengths of the staple line or serosal laceration, both were better in the slow-firing group. Conclusions: Tri-staple™ reloads offered more secure staple formation compared with the Universal reload. Although slow firing improved staple line shortening and serosal laceration, its effect on secure stapling was relatively small when using Tri-staple™ reloads.

Skin Stapler is an alternative instrument, which makes surgy easily and quickly and owns fine-looking effect without scars after the wound healed, to traditional surgical suture for the wound skin sewing. Magnesium recently is considered to develop medical implants because of its beneficial biocompatibility and bioabsorability. Due its less mechanical strength than traditional 316L stainless steel used in common staple, this paper try to optimize the structure of pure magnesium skin staple by FEM models and simulation as so to assure its biomechanical safty. Using ADINA software, two staples with different pre-bended shoulders and the traditional staple without shoulder are modeling to analyze its stress and plastical strain during structural deformation under load. The results, not only of pure magnesium models but also of 316L stainless steel models, showed that the shoulders optimization on staple structure has important role in its mechanical performance. The research increases the possibility of bioabsorable magnesium material application on medical skin staple.

This study aimed to compare patients’ satisfaction and outcome of caesarean section wound closure by skin staples and subcuticular suture at discharge and 6 weeks of postoperation. It was a randomized controlled trial of pregnant women scheduled for caesarean section at the University College Hospital, Ibadan, Nigeria, allocating them to wound closure by skin staples or subcuticular suture. Pain was assessed using the box numeric pain scale. Scar assessments were by patient, research nurse, and independent observers using the visual analogue scale, modified patient observer scar assessment scale, and patient satisfaction scale. Operation time (minutes) was significantly shorter in the staple group, 40.26 (±16.53) compared to 47.55 (±14.55) in the suture group (P=0.025). Skin closure time (seconds) was significantly less in the staple group, 118.62 (±69.68) versus 388.70 (±170.40) in the suture group (P≤0.001). There was no difference in pain experienced, wound assessment by the participants, and patients’ satisfaction. Participants in the staple group scored higher on both scar assessment scales by the nurse (P=0.044). Cost comparison analysis showed that staple use costs significantly more than suture use (P<0.001). The perceived benefit of subcuticular suture over skin staples was not observed and participants were satisfied with both wound closure techniques.

Full textAbstract:
We performed a retrospective clinical and radiological case control study on 22 rheumatoid wrists following radiolunate fusion via Shapiro staples with a mean follow-up of 5 years. Radiographs showed one early loosening through dorsal staple migration and four nonunions. Six wrists fused in mild ulnopalmar dislocation of the lunate. Primary intra-articular positioning of a staple was found in nine wrists, secondary intra-articular staple dislocation was found in two wrists. Dorsal staple dislocation was found in four fused arthrodeses. Osteolysis around the staples was found in all but two wrists. In contrast to unsatisfactory radiological results the clinical results were good or excellent in 18 patients. Good and excellent clinical results in the majority of the patients following radiolunate fusion does not depend on the fixation device. Nevertheless staple fixation of the radiolunate joint in the rheumatoid wrist is associated with a high rate of radiological complications.

Background Surgical site infections (SSIs) are common postoperative complications. Whether the use of staples or sutures makes a difference in abdominal surgery’s infection rate remains elusive. Methods A systematic review was performed to identify randomized clinical trials comparing staples and sutures after abdominal surgeries. Eligibility criteria involved the SSI occurrence as the primary outcome and the incidence of wound dehiscence, closure time, cosmesis, and patient satisfaction as the secondary outcomes. Results Of the 278 studies identified, seven randomized controlled trials representing 3705 patients were included in this review. There was no significant difference in SSI rates between sutures and staples in general (OR = 0.98, 95% CI = 0.79–1.22, I2 = 44%, P = 0.1) or in a subgroup of gastrointestinal surgery, where subcuticular suturing was found with a comparable SSI risk with skin stapling (OR = 0.85, 95% CI = 0.66–1.09). Staple closure was associated with a shorter surgery duration, whereas sutures appeared to provide better cosmesis and patient satisfaction. Sutures and staples achieved a comparable incidence of dehiscence. There was no significant between-study publication bias. Conclusion Our study demonstrated similar outcomes in SSI rate between subcuticular sutures and staples for skin closure in patients undergoing abdominal surgery.

Background: Midcarpal arthrodesis is a treatment of choice in patients with midcarpal arthritis. Traditionally a four corner fusion has been favoured, however recent research has shown improved results when the triquetrum and scaphoid are excised. There is no clear evidence as to which remaining bones should be fused or which implants should be used. The purpose of this study is to compare the biomechanics of midcarpal arthrodesis after scaphoid and triquetrum excision, using memory staples or cannulated screws, in recognised construct patterns. Methods: 36 identical sets of carpal bones were 3D printed from acetyl butyl styrene. Midcarpal arthrodeses were performed in three configurations with shape memory alloy staples or headless compression screws. This gave 6 treatment groups; lunocapitate single staple or screw, lunocapitate with 2 staples or screws, three corner fusion with 2 staples or screws. Peak torque to distraction was measured and analysed. Results: The peak torque to distraction was significantly greater in almost all constructs utilizing screws compared to staples, with two lunocapitate screws having the highest peak torque at both 1 and 3 mm distraction with 244 Nmm and 749 Nmm respectively (p < 0.05). Conclusions: Constructs utilizing screws have a peak torque to distraction significantly higher when compared to staples. Our recommendation when performing a midcarpal arthrodesis after scaphoid and trapezium excision is to fuse the midcarpal joint with 2 headless compression screws.

Background: To compare cosmetic appearance of skin closure wound by three methods -sutures, staples and skin adhesive glue. Traditional skin closure using sutures causes more pain, infection, needs its removal, time consuming and leaves behind bad scar. Nowadays, good cosmetic appearance of operated site is appealing among patients. Surgeons are looking for faster, comfortable and cosmetically best technique for skin closure. Newer techniques need to be evaluated which are better than suture and staples. 2-octylcyanoacrylate is easier to use, flexible, water resistant, pain free sealed skin closure without its need for removal and has better cosmesis.Methods: This study is conducted from July 2010 to April 2013 in 90 patients at LTMG Hospital. Wounds of clean surgeries closed with suture material, skin staples and skin adhesive glue were studied in 30 patients each. Patients were randomized using standardized methods. Patients followed up over period of 28 days and their scars were assessed according to the modified Hollander cosmesis scale(MHCS) and cosmetic visual analogue scale(VAS). Patient allotment was done using random number table.Results: Mean MHCS score for skin adhesive group on day 7 was 4.83 which was significantly more than 3.90for suture and 3.97 for stapler. Mean VAS score for skin adhesive group on day 7 was 67.67 which was significantly more than 61.67 for suture and stapler each. Mean MHCS and VAS score for skin adhesive group on day 7, 14 and 28 were significantly more than suture and stapler groups.Conclusions: Octylcyanoacrylate can be used for skin closure in clean elective surgeries with better cosmetic outcome as compared to staples and sutures.

Background: Wound closure is as important as any other action performed by the surgeon. Apart from the need for producing a healthy and strong scar, it is the surgeon’s responsibility to ensure its aesthetically pleasing physical appearance. Skin staples are an alternative to regular sutures in offering this advantage. The present study has helped to highlight the benefits of skin stapler.Methods: Out of the 120 participants, 60 underwent skin closure with Stainless steel skin staples and the remaining 60 with non-absorbable Polyamide mattress sutures randomly. They all received one mandatory dose of pre-operative parenteral antibiotic 1 hour prior to the incision. On the 3rd postoperative day, the wound was evaluated for inflammation, infection and wound gape. Participants were re-evaluated for infection/gape/inflammation during follow-up on 7th day. The wounds were evaluated at 1 months follow up which were rated for cosmesis by Visual Analogue Score. The data was coded and entered in Microsoft excel and then analysed using statistical software SSPS.Results: Study population consisted of 79 males (65.8%) and 41 females (34.2%). Mean age of the study population was 49.35 with an SD 16.739. Wound infection was found to be higher in stapler group (30%) when compared to conventional suture group (11.7%)which was found to be statistically significant with chi-square value 6.114 and p value 0.013. Mean time for closure was significantly shorter in stapler group 4.55 minutes, when compared to suture group (11.22 minutes). Better cosmetic outcome was observed in conventional suture group.Conclusions: Preventing wound infection, especially in abdominal wounds, is of importance as it may lead to wound gaping. Incidence of post-operative wound infection was more with skin staples. Cosmesis is essential and important aspect in this day and age. A cosmetic scar not only gives satisfaction to the patient but also mental ease to the surgeon. Conventional sutures provided better cosmetic result when compared with skin staplers.

Category: Trauma; Midfoot/Forefoot Introduction/Purpose: Primary arthrodesis of Lisfranc and midfoot fracture-dislocations is a reliable treatment option, yet concerns remain about nonunion and dorsiflexion malunion. The use of a new generation of nitinol staples has proliferated in midfoot arthrodesis. The purpose of this study is to examine the use of nitinol staples in primary arthrodesis of acute Lisfranc fracture-dislocations, comparing outcomes to traditional plate and screw fixation. The primary hypothesis is that nonunion rates are lower with constructs that include nitinol staples than those with plates and screws alone. Secondary hypotheses are: 1. Total operative and tourniquet time are shorter using nitinol staples. 2. Reoperation rates are lower using nitinol staples. 3. Dorsiflexion malunion rates are lower using nitinol staples. 4. Functional outcome scores will indicate comparable post-arthrodesis disability. Methods: Midfoot fracture-dislocations treated with primary arthrodesis by seven foot and ankle orthopaedic surgeons at a tertiary referral center from 1/1/2012 to 8/1/2021 were reviewed. Patients with open fractures, fractures managed with external fixation, Charcot arthropathy, neuropathy, previous midfoot surgery, or concomitant hindfoot/ankle fractures were excluded. Of the 160 eligible patients, 121 met the required 4-month minimum radiographic follow-up. Preoperative imaging and operative records were reviewed, evaluating for associated metatarsal and cuneiform fractures, operative and tourniquet time, joints included, and fixation construct. Patients and individual joints (303 total) were categorized as either staples alone (47 patients), staples plus plates and screws (hybrid) (47), or plates and screws alone (35). Postoperative radiographs at last follow-up were then analyzed for union and malunion at each joint fused. CT scans were used, when available (41 patients), to assess for union. Medical records were reviewed for postoperative complications. FAAM, VR-12, and NPRS were collected. Results: When assessed at the individual joint level, the nonunion rate was higher (8%, 9/101) among joints fixed with plate and screw constructs than with hybrid (2.4%, 1/41) or staple only constructs (1.3%, 2/152) (P = 0.015). Of the 12 nonunions in the study, 6 had either a metatarsal or cuneiform fracture. Median OR and tourniquet time were both shorter for hybrid (92 & 83 minutes) and staple only (67 & 63 minutes) constructs than plate and screw only fixation (107 & 96 minutes) (P = 0.0002 & 0.0009). There were 17 (14%) reoperations including 10 hardware removals, 3 nonunion revisions, and 1 malunion revision. There was no difference in reoperation, malunion (14 total, 12%), or patient reported outcome measure between fixation types. Conclusion: Nitinol staples are effective in achieving bony fusion when used alone or in combination with plates and screws. With lower rates of nonunion and shorter tourniquet and operative time compared to traditional plate and screw fixation, their use should be considered for primary arthrodesis of Lisfranc and midfoot fracture-dislocations. Further studies are needed to determine if staples decrease the risk for dorsiflexion malunion and improve patient reported outcomes.

The withdrawal and lateral holding properties of three types of plywood with one stapled as well as one-row multi-stapled joints were studied and compared. The results show that variations in plywood density have a significant effect on withdrawal strength and a relatively small effect on lateral holding strength. At four staples, the withdrawal strength of the eucalyptus plywood with a density of 0.59 g/cm3 is 1821 N, which is 21% higher than that of poplar plywood with a density of 0.51 g/cm3 at 1498 N and 32% higher than that of eucalyptus/poplar composite plywood with a density of 0.53 g/cm3 at 1275 N. In terms of lateral holding strength, eucalyptus plywood has a lateral holding strength of 1603 N 12% lower than the 1807 N of eucalyptus/poplar composite plywood and 10% lower than the 1761 N of poplar plywood. As the number of staples increased from 1 to 4 in increments of 1, the withdrawal strength of eucalyptus plywood continued to increase, while the nodal strengths of the poplar plywood as well as eucalyptus/poplar composite plywood did not differ significantly between 3 and 4 staples, and there is a significant increase in the lateral holding strength for all three plywood nodes. Equations for predicting the withdrawal and lateral holding strengths of one-row multi-stapled joints were derived separately.

AbstractBackground:Endoscopic hypopharyngeal diverticulotomy is now largely performed using an endoscopic stapling device. A poorly applied endoscopic stapling device can result in incomplete division of the cricopharyngeal bar, necessitating the application of a second set of staples. Applying more than one set of staples is associated with an increased risk of complications and greater cost. Small pharyngeal pouches are difficult to staple because of difficulties engaging the stapling device over the cricopharyngeal bar.Method:Two pairs of oesophageal forceps are used in conjunction with a 0 degree Hopkins rod to optimise the endoscopic stapling of small and large pharyngeal pouches.Results and conclusion:Applying grasping forceps to the cricopharyngeal bar improves the accuracy of the stapling procedure, thus reducing the morbidity and cost associated with multiple staple applications.

On 1 March 1989 the Australian Conciliation and Arbitration Commission was abolished and replaced by the Australian Industrial Relations Commission. All of the members of the old commission were appointed to the same office in the new except one, Justice Staples, a deputy president since 1975. Despite requests, no reasons were given to Justice Staples for his non-appointment in 1989 to the new commission. In Parliament, Prime Minister R. J. Hawke eventually explained it as based on the failure of successive presidents to assign Justice Staples duties. This paper places the events of Justice Staples's career in the Arbitration Commission in the context of the history of the commission and its predecessors. It outlines the controversy involving Justice Staples and how it first arose, and then traces the steps leading to his purported removal from office. The responses of the Australian legal profession, the judiciary, the media, the industrial relations community and parliamentarians are traced. Although the prime minister has declared that the concerns expressed in the legal profession are 'contrived nonsense', the author suggests that important conventions have been breached and that significant principles of universal application are involved in what happened to Justice Staples.

Full textAbstract:
Abstract Introduction A critical component of split-thickness skin grafting is the fixation of the skin graft to the wound site. Graft displacement can result in graft failure, especially during the initial 48–72 hours following application. The most common method of securing grafts is with the use of staples, sometimes with the addition of fibrin glue in order to aid both graft adhesion and homeostasis. The use of staples, however, is associated with significant levels of patient discomfort, especially during staple removal. A possible alternative to staples is the use of liquid adhesives, in combination with steri-strips, to anchor the edges of skin grafts to intact skin. Certain liquid adhesives, such as gum-based resins, are cheaper to use than staples and offer the potential to secure small split-thickness skin grafts without the associated pain of staples. In this pilot study, we examined the effectiveness of using a combination of gum-based resin (Gum Mastic-Storax-Msal-Alcohol), fibrin glue, and steri-strips to secure partial-thickness grafts in 8 patients without the use of staples or sutures. Methods Patients were included in the study who required split-thickness skin grafts to treat wounds involving less than or equal to 15% total surface body area and whose wounds were not located in areas prone to graft displacement, such as the axilla and groin. For each patient, skin grafts were secured using fibrin glue (sprayed over the entire wound), and a combination of liquid adhesive and steri-strips applied around the wound perimeter. The success of each graft was determined by the percentage of graft take. Results From January 1st, 2020 to April 30th, 2020, 8 patients were identified who fit the inclusion criteria. Five of the patients received grafts to their lower extremities, two patients received grafts to their upper extremities, and one of the patients received a graft to the torso. The average wound site that was grafted was 116.7 cm2. Average graft take among the 8 patients was 96.9%, with a range of 90%-100%. No complications at the graft site were noted, such as hematomas or any other event that resulted in graft displacement or failure. Conclusions The results of the study demonstrate that a combination of liquid adhesive, fibrin glue, and steri-strips, can be used as an effective alternative to staples in small split-thickness skin grafts. The use of liquid adhesive in place of staples was advantageous because it eliminated to need for staple removal, which resulted in less discomfort for the patient and less work for the nursing staff.

Vitamin A deficiency is a major public health problem in Nigeria. Staple crops are targeted by biofortification efforts because they possess low micronutrient density and are consumed in large quantities by a large proportion of poor households. This study was designed to assess the knowledge, perception and utilization of biofortified cassava and orange-fleshed sweet potato in selected Local government Areas in Abia and Imo States. The study was descriptive and cross-sectional in design. A total of 710 respondents were selected using a multi-stage sampling technique. A structured interviewer-administered questionnaire was used to elicit the required information. Statistical analysis was performed using descriptive statistics(frequency, percentage, mean and standard deviation)and inferential(correlation)analysis. Socio-demographic data revealed a preponderance of females, married, well-educated and working-class respondents. Monthly income above ₦29,000(US$ 70.54) and household size of 4-6 members were reported in 53.5% and 48.6% of the respondents. Study results further revealed that some (34.9%)of the respondents had good knowledge, while 46.1% and 19.0% had an average and poor knowledge of biofortified staples, respectively. Orange fleshed sweet potatoes and biofortified cassava were purchased at least once monthly by 73.7% of the respondents, however 16.5% and 27.5% of the respondents consumed these biofortified staples on a daily and weekly basis. Low positive perception towards the consumption (27.5%), benefits (39.6%) and barriers (16.9%) of utilizing studied biofortified staples was reported. A positive correlation was observed between respondents’ knowledge of biofortified staples and their benefits perception (p = 0.003), purchase (p =0.001) and consumption (p= 0.001) frequency.Therefore, while a good number of the respondents were fairly knowledgeable about the studied biofortified staples, it significantly influenced the perception and utilization of these staples, despite being reportedly low. Therefore, increased sensitization, price subsidy and availability of these biofortified staples will help improvetheir acceptance and utilization among rural households.

Background: Adult articular cartilage has limited potential for healing. A new cell technology in which chondrocytes expanded in monolayer culture are transplanted into the cartilage defect of the knee has been introduced. A scaffold is used to hold tissue to the defect area while it heals. Methods: Sixteen paired, fresh-frozen cadaver knees were used. Full-thickness chondral defects of 2 cm × 3 cm were made on either medial or lateral femoral condyles. The scaffold, made of PGA/PLA foam reinforced by PDS mesh, was implanted into a prepared defect area using three or five PDS/PGA staples as the fixation approach. A custom-made fixation system was used to attach each knee to a material testing machine. Each knee was tested for 10 000 cycles at 1 Hz. Upon completion, knees were examined and rated on a semiquantitative scale for damage of the chondral and meniscal surfaces, and for wear and retention of the scaffold and staples. Findings: Implanted scaffolds were retained fully in defect spaces in all cases. No tearing or peeling of the scaffold was observed. The number of staples used for fixation did not influence the wear or retention of scaffolds and staples. Wearing to the adjacent cartilage or meniscal surfaces was undetectable. Results were similar, regardless of whether the scaffold was located in the medial or lateral condyle. No staple was found loose after 10 000 cycles. Interpretation: Three staples were adequate and five staples were feasible to hold the scaffold for a defect size of 2 cm × 3 cm during continuous passive motion.

Metallic hemoclips or surgical staples were inserted in 16 tumor-bearing dogs at the time of surgical resection of the tumor. Orthogonal radiographs were taken immediately postoperatively and after wound healing to visualize the location and number of hemoclips or metallic staples. A shift in hemoclip/staple position was identified in nine dogs, mainly from positioning during radiography. In three dogs, an absolute shift in marker position was identified. Based on this study, it appears that the placement of surgical clips is potentially useful in identifying the tumor bed, which may be of benefit in establishing radiation treatment fields.

Full textAbstract:
Wood shear walls are the most common element in the lateral force-resisting system of residential construction. Recent developments have made the use of staples, as a sheathing-to-stud connection, much more feasible and practical. Dynamic cyclic tests of wood shear walls using staples as connectors of sheathing to the studs were performed to determine load and displacement capacities. Enhanced details from standard construction were used to improve the performance of the global system including a double sill plate, a new refined panel corner detail, double staples along blocked edges, and backup bolts for hold-downs. At the strength level, the stapled wood shear walls with enhanced details performed above the International Building Code-IBC (ICC 2006) regarding peak load capacity; however, peak drift capacity was 88% of the specified capacity. The test results were used to determine acceptance criteria, which were compared to the ASCE 41-06 Standard for Seismic Rehabilitation of Existing Buildings (ASCE 2007).

Full textAbstract:
The satiating capacity of carbohydrate staples eaten alone is dependent upon the energy density of the food but relative satiety when starchy staples are incorporated into mixed meals is uncertain. Our aim was to assess the satiating effects of three carbohydrate staples; jasmine rice, penne pasta, and Agria potato, each consumed within a standard mixed meal. Cooked portions of each staple containing 45 g carbohydrate were combined with 200 g of meat sauce and 200 g of mixed vegetables in three mixed meals. The quantities of staple providing 45 g carbohydrate were: Rice, 142 g; pasta, 138 g and potato 337 g. Participants (n = 14) consumed each of the mixed meals in random order on separate days. Satiety was assessed with using visual analogue scales at baseline and for 3 h post meal. In an area-under-the-curve comparison, participants felt less hungry (mean (SD)) following potato 263 (230) than following rice 374 (237) or pasta 444 (254) mm∙min, and felt fuller, more satisfied, and wanted to eat less following the potato compared with the rice and pasta meals (p for all <0.01). The superior satiating effect of potato compared with rice and pasta in a mixed meal was consistent with its lower energy density.

Full textAbstract:
A key outcome of the food policy reforms initiated in the 1980s in Mali was the liberalization of the cereals markets in order to stimulate agricultural production and reduce reliance on imported rice. These market reforms resulted in more variable food prices because grain prices were no longer fixed by the government but rather influenced by the seasonal pattern of production and availability, regional and international supply and demand conditions. Malian policy makers have often expressed their concerns about seasonal grain price variation in Mali. However, measurements of its immediate effects on households' effective demand for nutrients have been relatively scarce. This study uses panel data from a 2000-2001 household consumption survey undertaken in Bamako to estimate nutrient-income and price elasticities by season and for the entire year and examine the effects of intra-year price variation on nutrient demand. The study finds that real income has a statistically significant positive impact on the demand for calories, protein, calcium, vitamin A, and iron and that the income elasticities for calories (from 0.102 to 0.193) varies less across seasons than those for micronutrients (for example vitamin A from 0.492 to 0.725). During the lean season, a 10 percent increase in real incomes will improve calorie availability from staples and other foods by 1.36 and 3.36 percent, respectively. The pooled data results show that a 10 percent growth in real incomes will increase the demand for calories (+1.62 %), protein (+1.91%), calcium (+1.98%), vitamin A (+7.21%) and iron (+1.29%). The findings of this study have several implications for food policy design in Mali, and possibly for other Sahelian countries. The most striking result is that in the face of seasonal variations in the price of staples, Bamako households attempt to “defend” their calorie consumption by reducing the consumption of higher-cost but more nutrient -rich foods. Thus, the price fluctuations of staples can significantly affect the consumption of protein and micronutrients that the staples themselves do not contain. Measures to bring about more stability of the staple-food markets (regional trade policies, better infrastructure) would thus have impacts on nutrition and on the demands for other more nutrient-rich products well beyond the staple-foods. In other words, if you are interested in Vitamin A or iron consumption, the path to affect those most may be through the staple foods market, even though most Malian staples are not rich in those micronutrients.
