Aim: To compare the number of attempts at creating pneumoperitoneum for laparoscopic cholecystectomy using direct trocar versus veress needle insertion techniques. Design: Randomized controlled trial Place and Duration of Study: Department of Surgery, Allama Iqbal Memorial Hospital Sialkot and Govt. Sardar Begum Teaching Hospital, Sialkot from 27th September 2017 to 26th September 2020. Methodology: Six hundred and eight patients of both male and female patients, having uncomplicated cholelithiasis were selected. All participants were randomized into two equal groups, Group A (direct trocarInsertion) and the Group B (veress needle insertion). All trocars and veress needle used were disposable, with a safety shield. All procedures were carried out by the single experienced surgeons and his team. Data was noted, regarding age, sex, body mass index (BMI) and the number of attempts to create the successful pneumoperitoneum. Results: The number of attempts to create successful pneumoperitoneum in DTI group was significantly feweras compared to VNI group (p=0.026) but we found no statisticallysignificant difference between age, gender, and body mass index. Conclusion: The direct trocar insertion is a safe alternative to veress needle insertion in laparoscopic cholecystectomy because it requires fewernumber of attempts for successful creation of pneumoperitoneum as compared to the veress needle. Key words: Laparoscopic cholecystectomy, Veress needle insertion, Direct trocar insertion, Pneumoperitoneum

<em>Laparoscopic cholecystectomy has become a routinely used procedure for surgical removal of gall bladder in patients of Cholelithiasis. To minimize access related trauma, several techniques, numerous instruments, and multiple approaches have been introduced during the last century. These include the Veress pneumoperitoneum- trocar for &ldquo;classic&rdquo; or closed entry, the open (Hasson) technique, direct trocar insertion without prior pneumoperitoneum, use of shielded disposable trocars Direct trocar insertion (DTI) and veress needle insertion (VNI) techniques are the most common laparoscopic entry techniques. Objective: &nbsp;&nbsp;The objective of study is to compare the number of attempts for successful creation of pneumo-peritoneum using Veress Needle and Direct Trocar insertion in laparoscopic cholecystectomy. &nbsp;Study Design: Randomized Controlled Trial. &nbsp;Settings: Department of General Surgery, Bolan Medical Complex Hospital Quetta. </em> <em>Duration of study: 19-Dec-2019 to 18-Jun-2020. Patients and Methods: </em> <em>&nbsp;A total 188 patients with diagnosis of Cholelithiasis and planned for laparoscopic cholecystectomy having age 30-75 years of both genders were included. In all patients detailed history, followed by complete routine examination and baseline investigations were done. Patients were divided into two groups, Group A (Direct trocar entry), Group B (Veress Needle). All patients were kept in ward till clinically stabilized and management protocol was observed for all included patients. Results: &nbsp;Mean age of patients was 46.23&plusmn;11.28 years included in this study. Mean body mass index (BMI) was 25.10&plusmn;3.34 kg/m2. There were 108 (57.45%) females and 80 (42.55%) male patients. Successful creation of pneumoperitoneum in first attempt was done in 120 (63.83%), second attempt in 45 (23.94%) patients and in third attempt in 23 (12.23%) patients. successful creation of pneumo-peritoneum in first attempt was done in 69 (73.40%) patients in DTI group and in 51 (54.30%) in VNI group. While pneumo-peritoneum was created in second attempt in 16 (17.00%) patients in DTI group and in 29 (30.90%) patients in VNI group. Pneumo-peritoneum was created in third attempt in 09 (9.60%) patients in DTI group and in 14 (14.80%) patients in VNI group with p-value of 0.023. Conclusion: &nbsp;Direct trocar insertion (DTI) is a safe and quick technique for creation of pneumoperitoneum. Pneumoperitoneum can be successfully created in first attempt in higher number of patients in DTI group as compared to veress needle insertion (VNI).</em>

Background. Single-incision transumbilical laparoscopic liver resection (SITLLR) has been recently described in limited series. We report our experience in SITLLR and discuss the future of this approach in terms of indications, potential benefits, and limitations, with a special reference to laparoscopic liver resection (LLR). Patients and Methods. Six patients underwent SITLLR. Indications were biliary cysts (3 cases), hydatid cysts (2), and colorectal liver metastasis (1). Procedures consisted in cysts unroofing, left lateral lobectomy, pericystectomy, and wedge resection. SITLLR was performed with 11 mm reusable trocar, 10 or 5 mm 30° scopes, 10 mm ultrasound probe, curved reusable instruments, and straight disposable bipolar shears. Results. Neither conversion to open surgery nor insertion of supplementary trocars was necessary. Median laparoscopic time was 105.5 minutes and median blood loss 275 mL. Median final umbilical scar length was 1.5 cm, and median length of stay was 4 days. No early or late complications occurred. Conclusion. SITLLR remains a challenging procedure. It is feasible in highly selected patients, requiring experience in hepatobiliary and laparoscopic surgery and skills in single-incision laparoscopy. Apart from cosmetic benefit, our experience and literature review did not show significant advantages if compared with multiport LLR, underlying that specific indications remain to be established.

This study examines the design and development of a new disposable electric intelligent laparoscopic stapler and its components, addressing issues in existing electric staplers, particularly insufficient power for cutting thick tissue and postoperative complications. Finite element analysis was utilized to model cutting force and tissue thickness, optimizing the device’s cutting performance. The electric intelligent laparoscopic stapler integrates control, drive, transmission, execution, and communication modules, employing intelligent thickness detection and feedback mechanisms to enhance surgical precision and safety. Additionally, a degradable, absorbable hemostatic pad with excellent biocompatibility and an optimal degradation cycle was developed to minimize postoperative complications. The marketing strategy focuses on product diversification, competitive pricing, channel expansion, and technical services to strengthen the product’s presence in the domestic market and support import substitution, enhancing its competitiveness. A risk analysis was conducted to address potential policy, operational, technological, and market risks, with strategies proposed for mitigation.

Background. The laparoscopic cholecystectomy is a perfectly codified surgical procedure. The development of recent innovative and experimental surgical techniques Natural Orifice transluminal endoscopic surger (N.O.T.E.S.) which reduces the abdominal wall trauma leads us to develop a combined procedure of a standard dissection using miniaturised instruments already existing on the market (3 and 5 mm wide) and a gall bladder removal through a short gastrotomy Natural Orifice Specimen Extraction (N.O.S.E.).Methods. Our objective was to evaluate the safety, the feasibility, and the reproducibility of our new approach. After reviewing existing products on the market and a feasibility study, we put in place a protocol in our structure for patients on whom the procedure was performed. We carried out a gall bladder removal by a short gastrotomy, located on the anterior gastric wall, which then reduced the abdominal wall trauma and allowed them to resume normal physical activity quickly without risk of trocar site hernia.Results. We performed the procedure described in this paper on 63 patients, between April 2008 and July 2009. There were 14 men and 49 women with an average age of 46.8 years (ranging from 28 to 77) and an average BMI of 27.2. 30 patients had at least one gallstone larger than 10 mm. There was no postoperative gastric or abdominal wall complication and a fast recovery for all the patients in our study.Conclusions. This procedure is feasible, reproducible, with good results and minimal abdominal wall trauma. It is also safer than N.O.T.E.S. and endoscopic clipping and recovery, allowing normal physical activity, fast and, without risk of incisional hernia.
