Abstract:
Object Postoperative surgical site infections (SSIs) have been reported after 2–6% of spinal surgeries in most large series. The incidence of SSI can be < 1% after decompressive procedures and > 10% after instrumented fusions. Anecdotal evidence has suggested that there is a lower rate of SSI when minimally invasive techniques are used. Methods A retrospective review of prospectively collected databases of consecutive patients who underwent minimally invasive spinal surgery was performed. Minimally invasive spinal surgery was defined as any spinal procedure performed through a tubular retractor system. All surgeries were performed under standard sterile conditions with preoperative antibiotic prophylaxis. The databases were reviewed for any infectious complications. Cases of SSI were identified and reviewed for clinically relevant details. The incidence of postoperative SSIs was then calculated for the entire cohort as well as for subgroups based on the type of procedure performed, and then compared with an analogous series selected from an extensive literature review. Results The authors performed 1338 minimally invasive spinal surgeries in 1274 patients of average age 55.5 years. The primary diagnosis was degenerative in nature in 93% of cases. A single minimally invasive spinal surgery procedure was undertaken in 1213 patients, 2 procedures in 58, and 3 procedures in 3 patients. The region of surgery was lumbar in 85%, cervical in 12%, and thoracic in 3%. Simple decompressive procedures comprised 78%, instrumented arthrodeses 20%, and minimally invasive intradural procedures 2% of the collected cases. Three postoperative SSIs were detected, 2 were superficial and 1 deep. The procedural rate of SSI for simple decompression was 0.10%, and for minimally invasive fusion/fixation was 0.74%. The total SSI rate for the entire group was only 0.22%. Conclusions Minimally invasive spinal surgery techniques may reduce postoperative wound infections as much as 10-fold compared with other large, modern series of open spinal surgery published in the literature.

Abstract:
Introduction. Today absorbable suture material as well as plastic nonabsorbable clips are widely used for surgical haemostasis and stabilisation of sutures during minimally invasive operations, however, they are capable of potential and spontaneous migration into the lower and upper urinary tract.Objective. In this paper, we present clinical cases of clip migration after radical prostatectomy and renal resection.Clinical cases. Clinical cases of spontaneous clip migration after the two most common minimally invasive interventions: kidney resection with subsequent removal of a foreign body after the use of lithokinetic therapy and a case of hemostatic material migration after robot-assisted radical prostatectomy. The literature review is also available.Conclusion. Excessive use of non-absorbable plastic clips around their close contact with the kidney cavity or the bladder wall should be avoided to achieve adequate hemostasis during minimally invasive methods of treating patients.

Abstract:
In the Western countries, the incidence of esophageal carcinoma is 3-6 cases per 100.000 persons. Despite tremendous success of other therapeutic options, surgical treatment still represents the best therapeutic option whenever possible. For the long period, debate has centered on which of the available surgical procedures is superior - transhiatal or transthoracic esophagectomy. Minimally invasive esophagectomy (MIE) could offer both minimally invasive approach and proper mediastinal lymph node dissection. Minimally invasive esophagectomy is safe and adequate, but time consuming and technically demanding procedure. It is procedure reserved for the surgeons experienced in open esophagectomy for cancer, and specially trained in advanced minimally invasive procedures. Even in that case, learning curve is steep.

Abstract:
AbstractSurgery is an ever-evolving discipline and continually incorporates new technologies that have improved the ability of the operating room surgeon to perform. The next generation of minimally invasive surgery includes laparoscopic and robotic-assisted procedures. Graduating residents may be expected to have the skills to perform common colorectal procedures using these technologies, and residency programs are developing curriculums to teach these skills. Minimally invasive techniques are challenging and learning only by observation and practice alone is difficult. This requires dedicated training and mentoring.New simulation methods have been conceived specifically for minimally invasive procedures, and these embrace a combination of virtual reality simulators and box trainers, with animal and human tissue, as well as synthetic materials. The aim of this review is to provide an overview of training in minimally invasive colorectal surgery with a focus on different types of simulators that build the basis to develop and include a multistep training approach in a structured training curriculum for minimally invasive colorectal procedures.

Abstract:
The field of postgraduate minimally invasive surgery training has undergone substantial growth and change. A survey was sent to all program directors in surgery. Minimally invasive training patterns, facilities, their views, and performance of residents were examined. Ninety-five directors (38%) responded to the questionnaire. Of these, 51 per cent (n = 48) had a program size of three to four residents and 33 per cent (n = 31) had a program size of five to six residents. In 3 per cent of programs (n = 3), residents could not achieve the minimum Accreditation Council for Graduate Medical Education required numbers for advanced laparoscopic cases. Only 47 per cent of programs (n = 45) had dedicated rotations in minimally invasive surgery, ranging from 2 to 11 months. Up to 10 per cent (n = 9) of program directors felt that the current training in minimally invasive surgery was insufficient. Fifty-five per cent (n = 52) felt that laparoscopic adhesiolysis was an advanced laparoscopic procedure, and 33 per cent (n = 31) felt that there should be a separate minimum requirement for each of the commonly performed basic and advanced laparoscopic cases by Accreditation Council for Graduate Medical Education. Fifty-six per cent (n = 53) of programs were performing robotic surgery. Minimally invasive surgery training for surgical residents needs to increase opportunities so that they are able to perform laparoscopic procedures with confidence. There should be specific number requirements in each category of individual basic and advanced laparoscopic procedures.

Abstract:
The trend of using smaller operative corridors is seen in various surgical specialties. Neurosurgery has also recently embraced minimal access spine technique, and it has rapidly evolved over the past 2 decades. There has been a progression from needle access, small incisions with adaptation of the microscope, and automated percutaneous procedures to endoscopically and laparoscopically assisted procedures. More recently, new muscle-sparing technology has come into use with tubular access. This has now been adapted to the percutaneous placement of spinal instrumentation, including intervertebral spacers, rods, pedicle screws, facet screws, nucleus replacement devices, and artificial discs. New technologies involving hybrid procedures for the treatment of complex spine trauma are now on the horizon. Surgical corridors have been developed utilizing the interspinous space for X-STOP placement to treat lumbar stenosis in a minimally invasive fashion. The direct lateral retroperitoneal corridor has allowed for minimally invasive access to the anterior spine. In this report the authors present a chronological, historical perspective of minimal access spine technique and minimally invasive technologies in the lumbar, thoracic, and cervical spine from 1967 through 2009. Due to a low rate of complications, minimal soft tissue trauma, and reduced blood loss, more spine procedures are being performed in this manner. Spine surgery now entails shorter hospital stays and often is carried out on an outpatient basis. With education, training, and further research, more of our traditional open surgical management will be augmented or replaced by these technologies and approaches in the future.

Abstract:
Great advances have been made in the surgical management of esophageal disease since the first description of esophageal resection in 1913. We are in the era of minimally invasive esophagectomy. The current three main approaches to an esophagectomy are the Ivor Lewis technique, McKeown technique, and the transhiatal approach to esophagectomy. These operations were associated with a high morbidity and mortality. The recent advances in minimally invasive surgical techniques have greatly improved the outcomes of these surgical procedures. This article reviews the literature and describes the various techniques available for performing minimally invasive esophagectomy and robot-assisted esophagectomies, the history behind the development of these techniques, the variations, and the contemporary outcomes after such procedures.

Abstract:
North American pond sliders (Trachemys scripta) are invasive alien species that, following the release of pet specimens in the wild over the decades, have established breeding populations outside their native habitat, with detrimental effects on local biodiversity. Their commerce and breeding have been recently banned in the European Union, and national programs are being introduced by Union Members to eradicate and control their presence. Aims of the present PhD project were to elaborate on this species’ minimally invasive ovariectomy regarding surgical, anesthesiologic and analgesic aspects, and to dwell on the concept of population control, possibly providing means alternative to surgical gonadectomy. The first study included in the present thesis is a comparison between dorsal and lateral recumbency during endoscope assisted oophorectomy. Ovariectomy via the prefemoral fossa, with or without endoscopic assistance, is a well-described technique for elective and therapeutic sterilization in chelonians. The choice between lateral and dorsal recumbency is generally left to the surgeon’s preference, with no data supporting an objective superiority of one over the other. Twenty-four sexually mature female pond sliders were enrolled for this study, and were randomly divided in two groups: 12 animals were placed in right lateral recumbency with a left fossa approach (Group A), and 12 in dorsal recumbency with a right fossa approach (Group B). Scoring systems were applied to assess the ease of access to the coelomic cavity, and the ease of identification of the ovary opposite to the surgical incision; total surgery times and necessity to perform bilateral access were recorded. A negative correlation was found between the body weight of the animals and the ease of access to the coelom (p = 0.013), making the access easier in smaller animals. No significant difference was found between the two groups in terms of ease of access to the coelomic cavity, first ovary removal time, ease of identification of the second ovary, second ovary removal time, or total surgery time. It can be concluded that endoscope-assisted prefemoral ovariectomy in mature pond sliders can be indifferently performed in lateral or dorsal recumbency, depending on the preference of the surgeon, on the animal’s pathophysiologic status, or on the necessity to perform concurrent procedures. The second study is the description and comparison of two totally intramuscular anesthetic protocols. Chelonian anesthesia is a challenge for reptile practitioners: the capability of these animals to hold their breath for a considerable amount of time, and the ability of the chelonian heart to perform right-to-left shunts, make inhalant maintenance less predictable and reliable. Intravenous administration of anesthetic drugs can pose problems as well, since the difficulty of obtaining and maintaining IV catheters in non-complying patients. Anesthetic induction and maintenance by the intramuscular (IM) route circumvent these problems, but the number of multimodal protocols available for this purpose is limited. Twenty-six sexually mature female pond sliders undergoing elective prefemoral ovariectomy were enrolled for this study, and were randomly divided in two groups: Group A received a IM combination of ketamine 3 mg/kg + dexmedetomidine 0.1 mg/kg + midazolam 0.5 mg/kg + alfaxalone 8.5 mg/kg; Group B was premedicated with morphine 1 mg/kg IM 1 hour prior to induction, which was achieved via ketamine 3 mg/kg + dexmedetomidine 0.1 mg/kg + midazolam 0.5 mg/kg + alfaxalone 5 mg/kg IM. Time of loss of and recurrence of spontaneous movement, muscle and cloacal tone, and limb withdrawal latency, time to intubation, heart rate (HR), need for isoflurane administration, recovery time and total anesthesia time were recorded and compared between the two groups. Results indicate that IM administration of dexmedetomidine/ketamine/midazolam/alfaxalone alone (Group A) or in combination with morphine (Group B) provided an adequate anesthetic depth for surgical purpose respectively in 76.9% and 100% of animals, witnessed by the lack of reaction to skin incision and organs manipulation and resection. No marked cardiovascular effects were recorded but, if compared to basal values, Group B displayed a significantly lower HR in the first 15 minutes of surgery, likely determined by the cardiorespiratory effects of morphine. Protocol B showed quicker loss of measured parameters, shorter mean induction time (11 ± 5 vs 22 ±5 minutes, p = 0.00001), quicker recurrence of measured parameters and shorter recovery time (21 ±12 vs 36 ±22 minutes, p = 0.04). Both protocols were safe and provided quick induction and recovery time; premedication with morphine allowed to lower the dosage of alfaxalone, and the resulting protocol provided surgical anesthesia suitable for the whole length of the procedure without requiring inhalant maintenance. The third study evaluated the role of differentially expressed plasmatic micro RNAs (miRNAs) as possible biomarkers for surgical pain in pond sliders. Plasma of female turtles that underwent surgical gonadectomy were collected 24 hours pre-surgery, and 2.5 hours and 36 hours post-surgery; the expression of miRNAs was profiled by Next Generation Sequencing and the dysregulated miRNAs were validated using RT-qPCR. The diagnostic value of miRNAs was calculated by ROC curves, and the pointed out that, out of 14 differentially expressed miRNAs, miR-499-3p and miR-203-5p were effectively modulated. MiR-203-5p was fair (AUC: 0.7934) in discriminating pre-and 36h post-surgery samples and poor for other time points, while miR-499-3p was excellent (AUC: 0.944) in discriminating pre-surgery and 2.5h post-surgery samples, and fair in discriminating pre-surgery and 36h post-surgery (AUC:0.7292) and 2.5h and 36h post-surgery (AUC:0.7569) samples. In conclusion, it was demonstrated for the first time that miRNAs profile changes in plasma of turtles underwent surgical oophorectomy and identified miR-203-5p and miR-499-3p as potential candidate biomarkers. The last study investigated the efficacy of single and double IM 4.7 deslorelin acetate implant in suppressing fertility in female pond sliders. The use of long-acting GnRH-agonists has been poorly investigated in reptiles, and the few available studies show inconsistent results. Twenty sexually mature turtles were divided into three groups: one single-implant groups (6 animals), one double-implant group (6 animals) and one control group (no implant). During one reproductive season (March to October), plasmatic concentration of sexual hormones (estradiol, progesterone and testosterone) and ovarian morphometric activity via computed tomography were monitored about every 30 days. A significative (p = 0.011) decrease in the number of phase-II ovarian follicles was detected in the double-implant group when compared with the control group, but no significant difference was noted regarding the number of phase-III and phase-IV follicles, egg production, and sexual hormones plasmatic concentration. Results show that neither a single or double deslorelin acetate implant can successfully inhibit reproduction in female pond sliders during the ongoing season, but the lower number of phase-II follicles in the double-implant group can possibly be associated to a reduced fertility in following seasons. The present PhD project confirms the poor feasibility of non-surgical sterilization in chelonians and improves the knowledge on endoscopic-assisted ovariectomy, providing useful insight regarding not only the surgical procedure, but also regarding anesthesiologic concerns and pain management in these animals. Obtained results confirm this surgery as a highly specialistic procedures, and its massive application in the context of population control programs is questionable.

Laparoscopic surgery is a widespread and rapidly growing surgical technique. One of the challenges facing surgeons performing laparoscopic procedures is the retraction of anatomical structures that restrict vision and access to the surgical site. Current solutions to this problem involve opening additional incisions, which causes increased risk and discomfort to the patient. This study proposes a design for a laparoscopic retractor that can be inserted and operated without the need for additional incisions. The anatomical principles relevant to the design are introduced. The inventive problem is investigated and expressed as a problem statement, and the design requirements for the device are listed and explained. The processes of initial concept generation and selection are described, as well as the various stages of design refinement and prototyping performed on the chosen concept. User feedback regarding the alpha prototype of the device is presented. Finally, recommendations are made for future development of the device.

Abstract:
Internationally as well as in Sweden, efforts for improvement in gynaecological surgery in recent decades have mainly focused on three new treatment concepts: (1) Use of minimally invasive procedures: since there is an interdependency between the extent of surgical trauma and the risk for adverse outcome, increased use of supposedly atraumatic endoscopic procedures has revolutionized several aspects of surgical care (2) A multimodal approach to eliminate harmful procedures in the peri-operative process based on evidence-based principles (3) Introduction of implants to support damaged tissue with synthetic mesh in incontinence and pelvic organ prolapse patients. Research question 1: Is introduction of a minimally invasive operation enough per se or is the measured improvement mediated by elimination of harmful procedures in the perioperative process? Findings: Our study (Paper I) indicates that by applying a multimodal intervention programme for the pre- and postoperative care of patients undergoing supravaginal hysterectomy, the surgical procedure per se is of less importance than generally considered. Patient-related parameters such as length of postoperative hospital stay, number of days at home with need of painkillers, number of days before return to normal activities, and patient satisfaction did not differ between patients undergoing the laparoscopic procedure and patients undergoing abdominal supravaginal hysterectomy. When evaluating a new and presumably improved operative procedure against an established standard procedure, it is mandatory and of fundamental importance that the two methods are aligned in terms of perioperative care provided. Research question 2: Under which circumstances can it be assumed that a new surgical procedure showing promising efficacy in one setting can be reproduced with similar results in a different clinical setting (Paper I)? Findings: The operating surgeons concluded that, in their hands and under local conditions, laparoscopic technique for supravaginal hysterectomy was not superior to traditional open hysterectomy and stopped using laparoscopic technique. It seems necessary, prior to routine use, to monitor, using scientific tools, whether the advantages described in the literature are achievable under local conditions. Research question 3: Do expected advantages of implants outweigh the unwanted effects and complications caused by implants in operations for recurrent cystocele (Paper II)? Findings: Mesh has better durability but more (minor) complications. It is not possible to determine whether mesh is "generally better" than native tissue operation. Some may focus on the improved durability, others on the increased risks. The surgeon must make a risk assessment for each individual case. The patient must be sufficiently informed to understand the risks and make a personal, informed decision whether she wants an augmentation by implant. Essential for this process is a clear, comprehensible picture of both desired and unwanted effects of the planned surgery. In this context, studies like ours might be of use.

Abstract:
Les procédures otologiques impliquent la manipulation de petites structures délicates et complexes de l'anatomie de l'os temporal qui se trouvent à proximité de nerfs et de vaisseaux sanguins critiques. La réalité augmentée (RA) peut grandement être benéfique au domaine otologique en fournissant des informations supplémentaires anatomiques et de navigation fusionnée sur un seul écran. Cependant, bien que la navigation conventionnelle ait prouvé son utilité en otologie, le développement de la RA dans ce domaine reste limitée. Ce projet vise à développer des solutions RA pour les interventions chirurgicales de l'oreille moyenne et interne.Nous proposons deux applications de la RA à cet égard. Dans la première application, des informations sur les structures de l'oreille moyenne sont obtenues à partir d'un examen tomodensitométrique préopératoire et sont superposées à la vidéo chirurgicale de la membrane tympanique. Cela permet au chirurgien d'avoir des informations en temps réel sur les structures anatomiques cibles et l'instrument chirurgical localisés derrière la membrane tympanique sans élévation du volet tympanoméatal. En prolongement de ce système, nous proposons également de visualiser le modiolus cochléaire sur la vidéo chirurgicale de l'oreille moyenne et interne permettant l'implantation transmodiolaire de l'implant cochléaire à travers le conduit auditif externe.Les deux systèmes de RA proposés sont conçus de manière mini-invasive et sont uniquement basés sur des algorithmes de vision, éliminant la nécessité de systèmes traditionnels de suivi magnétique et/ou optique que l'installation dans l'environnement du bloc opératoire est facile. Ce travail ouvre des perspectives importantes sur les procédures otologiques mini-invasives grâce à des solutions basées sur la RA
Otologic procedures involve manipulation of small, delicate and complex structures in the temporal bone anatomy which are in close proxmity of critical nerves and blood vessels. Augmented reality (AR) can highly benefit the otological domain by providing supplementary anatomical and navigational information unified on a single display. However, despite being composed of mainly rigid bony structures, the awareness and acceptance of possibilities of AR systems in otology is fairly low. This project aims at developing video-based AR solutions for middle and inner ear surgical procedures.We propose two applications of AR in this regard. In the first application, information about middle ear cleft structures is obtained from a preoperative CT-scan exam and overlayed onto the surgical video of the tympanic membrane. This system provides the surgeon with real-time information about the anatomical target structures and the surgical instrument behind the tympanic membrane without tympanomeatal flap elevation. As an extension of this system, we also propose to visualize the cochlear modiolus in the real-time surgical video of the middle and inner ear cleft enabling transmodiolar implantation of the cochlear implant through the external auditory canal.Both proposed AR systems are designed in a minimally invasive manner and are solely based on vision algorithms eliminating the need for traditional magnetic and optical tracking systems. The first trials showed an easy installation in the operating room environment. This work opens important perspectives into minimally invasive otologic procedures through AR-based solutions

The needle-based procedures are usually considered minimally invasive. However, in insertion into soft tissues such as brain and liver, the tissue damage caused by needle insertion can be very significant. From the literature, it has been known that reduction in needle insertion and extraction forces as well as tissue deformation during the insertion results in less invasive procedure. This work aims to design and develop a new bioinspired design for surgical needles which reduce the insertion and extraction forces of the needle, and its damage to the tissue. Barbs in honeybee stinger decrease its insertion force significantly. Inspired by that finding, a new honeybee-inspired needle was designed and developed, and its insertion mechanics was studied. To study the insertion mechanics of honeybee-inspired needle, insertion tests into artificial and biological tissues were performed using both honeybee-inspired and conventional needles. The barb design parameters effects on needle forces were studied through multiple insertion and extraction tests into PVC gels. The design parameters values of the barbs were experimentally modified to further reduce the ultimate insertion and extraction forces of the needle. Bioinspired needle with modified barb design parameters values reduces the insertion force by 35%, and the extraction force by 20%. To show the relevance, the insertion tests into bovine liver and brain tissue were performed. Our results show that there was a 10-25% decrease in the insertion force for insertions into bovine brain, and a 35-45% reduction in the insertion force for insertions into the bovine liver using the proposed bioinspired needles. The bioinspired and conventional needles were manufactured in different scales and then used to study the size scale effect on our results. To do so, the insertion tests into tissue-mimicking PVC gels and liver tissues were performed. The results obtained for different sizes of the needle showed 25-46% decrease in the insertion force. The tissue deformations study was conducted to measure tissue deformation during the insertion using digital image correlation. The tissue deformation results showed 17% decrease in tissue deformation using barbed needles. A histological study was performed to accurately measure the damage caused by needle insertion. Our results showed 33% less tissue damage using bioinspired needles. The results of the histological study are in agreement with our hypothesis that reducing needle forces and tissue deformation lead to less invasive percutaneous procedures.

Abstract:
The current study examined the ability of pain-related catastrophizing to predict outcomes following non-surgical and surgical intervention for temporomandibular disorders (TMDs). The interpersonal context of pain-related catastrophizing, referred to as the communal coping model, was also examined to determine if patient perceptions of punishing and solicitous responses from significant others would moderate or mediate relations between pain catastrophizing and outcomes. The role of pain duration as a moderator of the relation between pain-related catastrophizing and perceived significant other responding was also examined. A total of 94 patients were identified for which 65 had follow-up outcomes that could be examined. Patient follow-up data were obtained at approximately two to three weeks, two to three months, and six months post-intervention. Results showed that pain-related catastrophizing was predictive of greater pain severity at all three follow-up time points after controlling for baseline levels of pain severity, depressive symptoms, sleep disturbance, and pain duration. Pain-related catastrophizing was predictive of poorer range of motion (ROM) at the initial follow-up after controlling for baseline levels of ROM, gender, and form of intervention. Pain-related catastrophizing was not associated with ROM at the second and third post-intervention follow-ups. There was no interaction between pain-related catastrophizing and perceptions of either solicitous or punishing responses in predicting post-intervention pain severity or ROM and any time point. Perceptions of significant other responses also did not mediate the relation between pain-related catastrophizing and post-intervention outcomes at any time point. Additionally, the interaction between pain duration and pain-related catastrophizing in the prediction of post-intervention pain severity or ROM was not significant at any follow-up time point. The findings indicate that pain related catastrophizing is an important predictor of pain severity following non-surgical and surgical interventions for TMDs both initially and in the long-term. Pain-related catastrophizing is related to ROM outcomes only in the short term. Perceptions of punishing and solicitous responses from significant others do not appear to play a role in these associations. The results suggest that patients with high levels of pre-intervention catastrophizing may benefit from adjunctive cognitive-behavioral intervention to attenuate post-intervention pain severity.

Abstract:
L’endométriose est une pathologie chronique qui provoque des douleurs pelviennes et une infertilité. On décrit trois phénotypes d’endométriose :l’endométriose péritonéale superficielle, les kystes ovariens d’endométriose (endométriomes) et l’endométriose profonde.L’examen standard pour le diagnostic de l’endométriose est, encore aujourd’hui, la laparoscopie. Nous avons étudié, de façon prospective, l’utilité d’un examen non invasif, la tomographie par émission de positrons (PET), chez les patientes avec suspicion d’endométriose. Nous n’avons pas mis en évidence d’hyperactivité métabolique sur les images de PET pré opératoires, après injection de déoxyglucose marqué au 18F (18FDG), des lésions d’endométriose ayant été confirmées par laparoscopie. Nous avons réalisé, dans un second temps, la même étude après injection d’un analogue de la somatostatine, le DOTATATE, marqué au 68Ga, qui montre une avidité pour les récepteurs à la somatostatine (SSTR) de type 2. Dans cette dernière étude, seules les lésions d’endométriose profonde se sont révélées hyperactives sur les images pré opératoires de PET. Nous avons ensuite réalisé une étude immunohistochimique rétrospective sur différents échantillons d’endométriose superficielle, d’endométriomes et d’endométriose profonde. Nos résultats ont confirmé l’expression de SSTR de type 1 et 5 par les cellules épithéliales des trois phénotypes d’endométriose. Par contre, seules les lésions d’endométriose profonde exprimaient les SSTR de type 2.Le traitement chirurgical des endométriomes et de l’endométriose superficielle est bien codifié. Par contre, la chirurgie de l’endométriose profonde reste au cœur des débats dans la littérature. Nous avons évalué notre aptitude à appliquer les techniques de chirurgie mini-invasive aux procédures complexes telles que la résection des nodules d’endométriose profonde du septum recto-vaginal (NEPSRV). Nous avons évalué la faisabilité de la laparoscopie avec assistance robotique pour une autre procédure complexe :la dissection des ganglions para-aortiques dans le cadre des cancers du col utérin localement avancés. Nous l’avons jugée faisable et sûre pour les patientes. En l’absence de bénéfice démontré de la laparoscopie avec assistance robotique sur la laparoscopie conventionnelle pour le traitement des NEPSRV, nous avons décidé d’évaluer une nouvelle stratégie opératoire mini-invasive de résection des NEPSRV. Nous avons réalisé une analyse des 10 premières patientes opérées selon cette stratégie et avons montré une amélioration significative des symptômes et de la qualité de vie des patientes. Nous avons également étudié la morbidité post opératoire. Nous avons finalement étudié l’apport de la laparoscopie guidée par la fluorescence au traitement des NEPSRV et observé des résultats prometteurs.A l’avenir, les lésions symptomatiques d’endométriose profonde exprimant les SSTR2 pourraient être sélectionnées à l’aide d’un PET au 68Ga-DOTATATE afin d’être traitées, dans le cadre d’essais cliniques, par des analogues de la somatostatine. Ces thérapies ciblées permettaient, dans ces cas, d’éviter la chirurgie. Notre stratégie opératoire mini-invasive pourraient dès lors être appliquée aux lésions n’exprimant pas les SSTR2.

Abstract:
Abstract Among all the novel glaucoma surgical devices, the XEN Gel Implant (Allergan plc, Dublin, Ireland) is the only one which uses an ab-interno approach to drain aqueous to the subconjunctival space, similar to conventional filtration surgery. Most MIGS procedures target the Schlemm’s canal and the collector channels which can be difficult to locate. The patency of the downstream drainage system cannot be accurately assessed and the episcleral venous pressure cannot be routinely measured, leading to unpredictable surgical outcomes for trabecular bypass surgery. In contrast, subconjunctival aqueous drainage is more effective at lowering the intraocular pressure, as is evidenced by the efficacy of trabeculectomy which has a long track record. The main advantages of the XEN Gel Implant over other filtering procedures include its less invasive surgical procedure and the favorable safety profile, fast visual recovery, and short surgery duration, rendering this implant particularly suited for patients who are unable to tolerate a long surgical duration or a delayed visual recovery. Although designed as a stand-alone procedure, XEN implantation can be combined with phacoemulsification in patients with concurrent cataract. Although its pressure-lowering ability appears to be superior to trabecular bypass and suprachoroidal MIGS devices, there are surgical nuances which can be difficult to master and the pre- and postoperative management is critical in the success of the XEN Glaucoma Treatment System.

Abstract:
Abstract Cycloablative or cyclodestructive procedures aim to lower intraocular pressure (IOP) by decreasing the function of the ciliary body and thereby decreasing the rate of aqueous production. Cycloablative procedures were typically used in refractory glaucoma in eyes with poor visual potential; however, more focused energy and targeted destruction of the ciliary body have led to an increase in cyclodestructive treatment options that are now an important adjunct to our surgical armamentarium. This chapter highlights the history of these procedures while focusing on current modalities including transscleral diode cyclophotocoagulation (TSCPC), micropulse transscleral diode cyclophotocoagulation (MP-TSCPC, MicroPulse P3, IRIDEX IQ810 Laser System, Mountain View, CA, USA), and High-Intensity Focused Ultrasound (HIFU). Specifically, this chapter discusses the protocols, indications, results, and complications of each featured procedure.

Abstract The design of an intracorpeal suturing device that will assist surgeons in placing an internal suture through a small incision. Performing surgical procedures through a small incision greatly reduces patient trauma and rehabilitation time, both of which are proportionally related to medical costs. Medical devices exists today that allow surgeons to perform procedures through small incisions, unfortunately, it is difficult to place sutures deep in the body using minimally invasive techniques. A device that enables surgeons to place sutures minimally invasively will facilitate surgeons by increasing the scope of procedures that can be preformed using this technique.

Abstract:
Computer-Aided techniques have been deployed more commonly in recent years to assist with surgical procedures, particularly in the case of minimally invasive surgeries. Arthroscopy, as one of the most prevailing minimally invasive surgical procedures, increases surgical complexity due to the loss of joint visibility, but has many advantages. More obstacles are encountered during hip arthroscopy, given the tight socket-joint hip anatomy. Therefore, computer-aided techniques could be used to ease such difficulties during hip arthroscopy.

Abstract:
Minimally invasive surgery (MIS) is known to be a difficult procedure to master due to its complexity, compared to traditional open surgery. Therefore, an objective and quantitative assessment tool is highly required in MIS, which can be used for determining surgeon’s skills, evaluating educational programs and providing subjects with unbiased feedback. The goal of this paper is to review various assessment methods, summarize capabilities of the methods, and suggest future possible improvements. Specifically, this paper categorize existing methods into two groups: the first and the most well known group focuses on the analysis of surgical motions, and the other group uses force and torque as a key metric. Specifically, motion analysis includes tracking the body, tool, or hand motions of a surgeon, either from teleoperated robotic systems or surgical simulators using different sensors like wireless or electromagnetic motion tracking sensors, video-glove-based input devices, optical tracking system, or magnetic tracking technologies. Sometimes data explored form this method is synchronized with eye-gaze data (what a surgeon looks at while operating), or videographic data. Using motion analysis actually the number of movements, rate of movements, total path length, movement variability, time taken to complete the operation, average or peak velocity are considered for assessing surgical skills. On the other hand, the methods in the second group assess the skills based on force and toque data that surgeons apply through surgical instruments. More specifically, these methods use different kind of sensors placed on the grasper. Different force and torque measurement systems, hidden-Markov-model-based analysis, simulated models with criteria, and Virtual reality have been developed, allowing for the quantification of the performance of surgeons. Although, each method has its own advantageous, and according to the kind of surgical task and evaluation, these methods can be used successfully to assess surgical skills, to provide predictive validity for each of these methods more study is needed. Also, future works should improve the efficiency of each method and move toward automated, low-cost and real time assessment methods.

Abstract:
Minimally invasive surgery (MIS) or laparoscopic surgery has changed the focus of surgery and has become an alternative to open surgical procedures. Operations are performed through small incisions in the abdomen thus avoiding the need for large incisions. This results in less tissue trauma, less scarring, and faster post-operative recovery time. However, the inherent challenges of laparoscopic procedures include limited visibility, constrained working space and the need for advanced surgical tools to safely and efficiently perform the surgical procedure. It is also necessary for surgeons to obtain advanced surgical training to perform these procedures.

Abstract:
Minimally invasive surgery (MIS) has become the standard approach for an increasing number and variety of procedures. Designing devices for such surgeries presents many challenges and must address efficiency, accuracy, and ease of use. The complexity of a device’s design likely influences its performance in real life situations. Therefore, identifying the complexity and potential for failures of a device is crucial in the early stage of design in order to ensure the effectiveness and safety of the final product. A complexity measure is explored utilizing design variables such as the maximum number of connections, number of total elements, and number of unique elements within a device. Reverse engineering of medical devices has been completed to begin understanding such complexity variables. The overall objective of this research is to determine the correlation between a medical device’s complexity measure and its failure modes. The nature and frequency of problems associated with various surgical medical devices must be characterized. This paper is an initial investigation and focuses on surgical stapling devices for MIS. The analysis pertains strictly to surgical staplers that simultaneously staple and transect tissue with a design that allows insertion through small incisions via a trocar, wound protector and retractor, or direct insertion. Adverse event reports involving minimally invasive surgical staplers have been retrieved from the U.S. Food and Drug Administration (FDA) Manufacturer and User Facility Device Experience (MAUDE) database from January 2006 – January 2016 and examined to determine trends in the characterization of device problems and prevalence of such problems. A total of 13,312 reports are included in the analysis. 106 events resulted in death, 3234 resulted in injury, and 9972 involved a device malfunction. A yearly analysis has been conducted analyzing the trends in event type (death, injury, and malfunction) and device brands involved in the reports over the past decade. A sample of reports was taken in order to perform a detailed analysis of the event descriptions. The reports are categorized by phase and description of failure modes associated with surgical stapler use. The phases of use in which failures occur have been identified as packaging, reload, articulation, application, firing, cutting, removal, and staple line. FDA recall information associated with these devices was also investigated. An extensive study regarding adverse events reported to the FDA associated with surgical staplers has not been completed since 2004 to the authors’ knowledge, nor a study investigating this specific category of surgical stapling devices. These devices are constantly evolving in regards to their design features, and their application is expanding to more wideranging open and MIS procedures. Despite the prevalence of minimally invasive surgical stapler use, any incident of failure may put a patient’s health and safety at risk. Malformed staples as a result of the firing phase, removal issues, and leaking staple lines were the main contributors to surgical stapler failure in the adverse event reports analyzed. Bariatric and thoracic surgery accounted for the majority of procedure types identified within the reports. The range of procedures in the analysis verifies the expansion of surgical stapler use and application. Various failure modes can be attributed to user error; however, the FDA recall information associated with these devices indicates that device failure shares responsibility. The results of this work contribute to the awareness of both surgical stapling device designers and users, and the importance of such must be heavily emphasized in order to prevent future complications in the field.

Abstract:
In minimally invasive surgery, the positions of surgical tools are important in multiple instruments set-up and procedures. Typically, each surgery requires 4–5 incision holes and for each specific procedure, the layout of points defines specific pattern. Taking advantage of this possible one-to-one relationship between a specific procedure in minimally invasive surgery and the incision patterns, such patterns can be utilized in tele-monitoring of trainee during an emulated surgical operation. For example, in performance evaluation of trainee, this procedure would automatically estimate and verify the initial incision pattern to that of the predefined expected template associated with a particular surgical procedure. In this paper, we propose and analyze two models, based on color and shape respectively, to reconstruct the pattern. Both approaches use image information only to reconstruct the incision patterns in three dimensional space. The challenge of monocular endoscopic view is the lack of depth perception which hindered the vision-based tracking of laparoscopic tools. To address the problem, we present a method to determine not only the spatial tip position of the surgical tools, but also their orientation with respect to the camera coordinate frame. Detailed formulation shows that how segmented tool edges and camera field of view localize the 3D orientations of tools. Then, 3D position of the tool tip is reconstructed using either color or edge detection method. Finally, the orientations and the position of tool tips uniquely determine the poses of the tools. From above procedures, geometrical models of cylindrical tools can be constructed in each sequence of mono-camera images. To further use the tracking result in order to localize the incision point, we computed the vectors of the cylindrical tool center lines at multiple poses at number of frames. Extracted incision point is further analyzed as a recognition pattern to map into the patients’ pre-operative incision procedure. Accuracy of 3D tool pose estimation and incision pattern is evaluated in real image sequences with known ground truth.

Abstract:
Review question / Objective: Whether is indocyanine green fluorescence imaging-guided lymphadenectomy feasible to improve the number of lymph node dissections during radical gastrectomy in patients with gastric cancer undergoing curative resection? Condition being studied: Gastric cancer was the sixth most common malignant tumor and the fourth leading cause of cancer-related death in the world. Radical lymphadenectomy was a standard procedure in radical gastrectomy for gastric cancer. The retrieval of more lymph nodes was beneficial for improving the accuracy of tumor staging and the long-term survival of patients with gastric cancer. Indocyanine green(ICG) near-infrared fluorescent imaging has been found to provide surgeons with effective visualization of the lymphatic anatomy. As a new surgical navigation technique, ICG near-infrared fluorescent imaging was a hot spot and had already demonstrated promising results in the localization of lymph nodes during surgery in patients with breast cancer, non–small cell lung cancer, and gastric cancer. In addition, ICG had increasingly been reported in the localization of tumor, lymph node dissection, and the evaluation of anastomotic blood supply during radical gastrectomy for gastric cancer. However, it remained unclear whether ICG fluorescence imaging would assist surgeons in performing safe and sufficient lymphadenectomy.

Abstract:
Background PHS (pulmonary hypertension syndrome, ascites syndrome) is a serious cause of loss in the broiler industry, and is a prime example of an undesirable side effect of successful genetic development that may be deleteriously manifested by factors in the environment of growing broilers. Basically, continuous and pinpointed selection for rapid growth in broilers has led to higher oxygen demand and consequently to more frequent manifestation of an inherent potential cardiopulmonary incapability to sufficiently oxygenate the arterial blood. The multifaceted causes and modifiers of PHS make research into finding solutions to the syndrome a complex and multi threaded challenge. This research used several directions to better understand the development of PHS and to probe possible means of achieving a goal of monitoring and increasing resistance to the syndrome. Research Objectives (1) To evaluate the growth dynamics of individuals within breeding stocks and their correlation with individual susceptibility or resistance to PHS; (2) To compile data on diagnostic indices found in this work to be predictive for PHS, during exposure to experimental protocols known to trigger PHS; (3) To conduct detailed physiological evaluations of cardiopulmonary function in broilers; (4) To compile data on growth dynamics and other diagnostic indices in existing lines selected for susceptibility or resistance to PHS; (5) To integrate growth dynamics and other diagnostic data within appropriate statistical procedures to provide geneticists with predictive indices that characterize resistance or susceptibility to PHS. Revisions In the first year, the US team acquired the costly Peckode weigh platform / individual bird I.D. system that was to provide the continuous (several times each day), automated weighing of birds, for a comprehensive monitoring of growth dynamics. However, data generated were found to be inaccurate and irreproducible, so making its use implausible. Henceforth, weighing was manual, this highly labor intensive work precluding some of the original objectives of using such a strategy of growth dynamics in selection procedures involving thousands of birds. Major conclusions, solutions, achievements 1. Healthy broilers were found to have greater oscillations in growth velocity and acceleration than PHS susceptible birds. This proved the scientific validity of our original hypothesis that such differences occur. 2. Growth rate in the first week is higher in PHS-susceptible than in PHS-resistant chicks. Artificial neural network accurately distinguished differences between the two groups based on growth patterns in this period. 3. In the US, the unilateral pulmonary occlusion technique was used in collaboration with a major broiler breeding company to create a commercial broiler line that is highly resistant to PHS induced by fast growth and low ambient temperatures. 4. In Israel, lines were obtained by genetic selection on PHS mortality after cold exposure in a dam-line population comprising of 85 sire families. The wide range of PHS incidence per family (0-50%), high heritability (about 0.6), and the results in cold challenged progeny, suggested a highly effective and relatively easy means for selection for PHS resistance 5. The best minimally-invasive diagnostic indices for prediction of PHS resistance were found to be oximetry, hematocrit values, heart rate and electrocardiographic (ECG) lead II waves. Some differences in results were found between the US and Israeli teams, probably reflecting genetic differences in the broiler strains used in the two countries. For instance the US team found the S wave amplitude to predict PHS susceptibility well, whereas the Israeli team found the P wave amplitude to be a better valid predictor. 6. Comprehensive physiological studies further increased knowledge on the development of PHS cardiopulmonary characteristics of pre-ascitic birds, pulmonary arterial wedge pressures, hypotension/kidney response, pulmonary hemodynamic responses to vasoactive mediators were all examined in depth. Implications, scientific and agricultural Substantial progress has been made in understanding the genetic and environmental factors involved in PHS, and their interaction. The two teams each successfully developed different selection programs, by surgical means and by divergent selection under cold challenge. Monitoring of the progress and success of the programs was done be using the in-depth estimations that this research engendered on the reliability and value of non-invasive predictive parameters. These findings helped corroborate the validity of practical means to improve PHT resistance by research-based programs of selection.

Abstract:
Review question / Objective: Although video-assisted thoracoscopic surgery is a minimally invasive surgical technique, the pain remains moderate to severe. We comprehensively compared the regional anesthesia methods for postoperative analgesia in patients undergoing video-assisted thoracoscopic surgery. Eligibility criteria: All published full-article RCTs comparing the analgesic efficacy of investigated regional anesthesia technique or comparative blocks in adult patients undergoing any VATS were eligible for inclusion. There were no language restrictions. Moreover, we also excluded case reports, non-RCT studies, incomplete clinical trials, and any trials used multiple nerve blocks. We also excluded any conference abstracts which could not offer enough information about the study design, or by data request to the author.
