Introduction: This study aimed to investigate the feasibility of applying laparoscopic transection and partial resection of hernia sac in the treatment of indirect inguinal hernia in children.

Patients and methods: From December 2017 to November 2018, we recruited 20 children, who were aged 1-6 years old, with indirect inguinal hernia. At the time of admission, the participants had already developed an indirect inguinal hernia for 6 months to 1 year. A simple transection and partial resection of hernia sac was performed at the internal ring on each of the recruited children. The procedure was conducted under laparoscopy. Two 5-mm trocars were placed on either side of the umbilicus, one for the camera and the other for a surgical instrument. Another trocar was placed on the right abdomen. Laparoscopic camera curved forceps, and scissors were placed. Along the unclosed internal ring, the peritoneum was cut in a circular fashion to transect the hernia sac and dissociate it from the distal end. About 1-2 cm of the hernia sac was resected.

Results: The operation was successfully completed in all 20 cases, who did not experience any complications, such as the absence of spermatic cord, vas deferens injury, scrotal swelling and incision infection. The children were discharged 1 day after the operation. In the post-operative follow-up for the first 3-4 years, recurrence and testicular atrophy did not occur in the study participants.

Conclusion: The short-term results obtained from this study showed that the application of laparoscopic transection and partial resection of hernia sac in the treatment of indirect inguinal hernia is feasible. Long-term results and further observation are needed for validation.

Introduction: Pancreaticojejunostomy have been studied and modified for more than a hundred years. We investigated a new method of pancreaticojejunostomy to explore its value in laparoscopic pancreaticoduodenectomy.

Patients and methods: A retrospective analysis was conducted on the clinical data of 93 patients who underwent laparoscopic pancreaticoduodenectomy with 'Shunt-block combined' pancreaticojejunostomy at Ningbo Medical Center Lihuili Hospital from April 2017 to February 2023.

Results: All patients successfully completed the surgery, with two cases requiring conversion to open surgery. The average operation time was 328.5 (180-532) min, the average intraoperative blood loss was 182.9 (50-1000) mL and the average laparoscopic pancreaticojejunostomy time was 29.6 (20-39) min. There were no cases of grade C pancreatic fistula postoperatively, 10 cases of grade B pancreatic fistula, 43 cases of biochemical fistula and 40 cases without detected pancreatic fistula.

Conclusion: 'Shunt-block combined' pancreaticojejunostomy was a safe and effective method for pancreaticojejunostomy in laparoscopic pancreaticoduodenectomy.

Abstract: We herein report a rare case of duodeno-duodenal intussusception (IS) presenting with obstruction caused by tubulovillous adenoma in an adult with malrotation that was managed by a novel laparoendoscopic hybrid technique. This was done by passing transjejunal nasogastric tube (NG) through one of the ports and manoeuvring it towards the IS. Two hundred and fifty millilitre of saline was flushed by aseptosyringe with pressure connected to the NG. This hydrostatic reduction technique resulted in distension of the jejunal and duodenal loop achieving reduction of IS. Intraoperative endoscopy was performed to exactly localise the mass lesion. The duodenum was kocherised and was delivered through a 4-cm transverse incision. Anterior duodenotomy was performed; the mass was excised; and duodenotomy was closed transversely. An extensive literature search did not show any case report of duodenoduodenal IS being managed by this technique. The combination of novel retrograde decompression and intraoperative endoscopy helped us to manage this rare case by this novel technique.

Abstract: Median arcuate ligament (MAL) syndrome or celiac artery (CA) compression syndrome previously treated mainly by vascular surgeons using the open approach is now being increasingly performed by general surgeons with training in advanced laparoscopy. Although this approach has all the advantages of minimal access surgery, the procedure is fraught with serious complications like injury to major vascular structures during dissection. Vascular injury by far is the major cause of conversion to open procedure. Herein, we report a laparoscopic repair of iatrogenic CA injury by intra-corporeal suturing during MAL release. We also elaborate the causes, the preventive measures that can be applied to avoid such catastrophic occurrences in future. To the best of our knowledge, this is the first report of a laparoscopic repair of CA bleed during MAL release.

Abstract: The revisional surgical techniques for managing weight regain after laparoscopic Roux-en-Y gastric bypass have lacked a clear gold standard. Various methods such as pouch minimising, gastroenterostomy narrowing and distalization have been described, but none have consistently achieved optimal success. This study introduces a combined revision technique that enables the reassessment of both alimentary limb and biliopancreatic limb lengths based on the individual patient's total bowel length. This approach aims to promote effective weight loss while minimising the pouch and gastroenterostomy.

Abstract: Small bowel lipomas are benign submucosal neoplasm composed mainly of mature adipose tissue. Despite their rare occurrence, lipomas are the second most common benign tumour of the small intestine. These tumours are mostly small in size and remain clinically asymptomatic. However, larger lesions tend to be more symptomatic, presenting with complications such as intussusception, bleeding or obstruction. Definitive surgical or endoscopic intervention is indicated in such symptomatic lipomas. Herein, we describe a rare case of ileal lipoma presenting with ileo-ileal intussusception and a life-threatening haemorrhage that was managed by laparoscopic-assisted ileal resection.

Introduction: This study aimed to study on clinical outcomes of single-stage (laparoscopic cholecystectomy [LC] and laparoscopic common bile duct [CBD] exploration using flexible videobronchoscope) versus dual-stage (endoscopic retrograde cholangiopancreatography followed by laparoscopic cholecystectomy) for cholelithiasis with choledocholithiasis-prospective study in a tertiary care centre (BRACE STUDY-Bronchoscope-Assisted CBD Exploration [CBDE] Study).

Patients and methods: Between April 2022 and April 2023, patients who underwent LC with laparoscopic CBDE and endoscopic retrograde cholangiopancreatography (ERCP) followed by LC participated in this single-centre prospective research. The Institute Ethics Committee granted its approval after receiving an ethical review. The primary endpoint of the proposed research was the removal of the gall bladder and CBD stones. The secondary outcomes studied were complications using the Clavien-Dindo score, cost-effectiveness, patient satisfaction score and post-procedure duration of hospital stay.

Results: A total of 168 patients were included in the study. The success rate of LC with laparoscopic CBD exploration using a flexible videobronchoscope (Group 1) was significantly higher as compared to ERCP f/b LC (Group 2) (96.4% vs. 84.5%, P value = 0.02). Out of the 84 patients in Group 1, direct choledochotomies were performed on 83 of them. Group 1 had a considerably shorter hospital stay (4.6 ± 2.4 vs. 5.3 ± 6.2 days; P = 0.03). Both the cost ( P = 0.002) and the number of procedures per patient ( P < 0.001) were considerably higher in Group 2. Major complications (Clavien-Dindo grade 3 and above) were significantly higher in Group 2 ( P = 0.04). Patient satisfaction in Group 1 scored more favourably than those in Group 2 (2.26 ± 0.3 vs. 1.92 ± 0.7; P = 0.006).

Conclusion: For concurrent gall bladder and CBD stones, single-stage management by LCBDE using a flexible videobronchoscope has a significantly better primary outcome and lower major complications than dual-stage management. The single-stage strategy also has advantages in terms of a shorter hospital stay, the need for fewer procedures, cost efficiency and patient satisfaction.

Introduction: The present study reports the first clinical experience with subcostal uniportal VATS (suVATS) compared with the conventional lateral uniportal VATS (luVATS) approach.

Patients and methods: All patients who underwent suVATS between January 2019 and April 2020 were included. Patients who had undergone luVATS for similar indications were included as the control group. The data were prospectively and retrospectively analysed.

Results: The suVATS group included 38 patients with a mean age of 61 (30-83) years. The luVATS group included 33 patients (mean age, 69 years; range: 46-89 years). An intercostal block was performed intraoperatively in the luVATS group. Local infiltration under anaesthesia was performed around the incision in the suVATS group. The duration of the surgery was significantly longer in the suVATS group. However, the chest tube treatment and hospital stay duration were significantly shorter in the suVATS group. The routinely recorded Visual Analogue Scale scores on the first post-operative day and the day of discharge were significantly lower in the suVATS group.

Conclusion: Subcostal uniportal VATS enables a shorter drainage treatment duration and hospital stay and significantly reduces post-operative pain. Thus, a faster patient recovery can be achieved.

Introduction: Laparoscopic Whipple's pancreaticoduodenectomy (WPD) is one of the most advanced minimally invasive procedures. In recent years, with advancements in minimally invasive surgery, laparoscopic WPD has been increasingly adopted as a safe and feasible technique. This study aims to compare the short-term and long-term outcomes of laparoscopic WPD to open WPD in resectable ampullary, periampullary and head of pancreas malignancies.

Patients and methods: A retrospective analysis of a prospectively maintained database of patients who underwent WPD from January 2015 to January 2021 at the department of surgical gastroenterology in a tertiary care medical college hospital was conducted. Patient demographics and pre-operative details, intraoperative parameters (operating time and blood loss), post-operative length of hospital stay, median intensive care unit (ICU) stay, time to resume oral diet, post-operative complications, interventional procedures, mortality, 3-year survival, 3 year recurrence-free survival and overall survival were analysed.

Results: Forty-two patients underwent WPD during our study period; 14 patients underwent laparoscopic WPD and 28 patients underwent open WPD. None required conversion. The majority of the patients had periampullary carcinoma in both the groups. Laparoscopic WPD showed a trend towards shorter ICU stays, hospital stays and surgical site infections (SSIs) compared to open WPD. The median operating time was significantly longer in the laparoscopic WPD group (380 min) compared to the open group (285 min). However, median blood loss was significantly lower in the laparoscopic group (250 mL vs. 300 mL). The pancreas-specific post-operative complications like delayed gastric emptying, post-operative pancreatic fistula or post-operative pancreatic haemorrhage did not differ significantly between the groups. All patients had R0 resection and the mean lymph node yield was comparable between the two groups (14.92 vs. 13.42). The reoperation rate or mortality rate did not show any statistical significance between the two groups. The overall survival was 46 months in the open group and 48 months in the laparoscopic group. Three-year survival was 74.1% in the open WPD group and 69.2% in the laparoscopic group. Three-year recurrence-free survival was 55.5% in the open group and 69.23% in the laparoscopic group.

Conclusion: Laparoscopic WPD appears to be safe and feasible, with similar short-term and long-term survival outcomes. With a trend favouring laparoscopic WPD in terms of blood loss, hospital and ICU stay and post-operative SSIs, it should be offered to selected patients when the expertise is available.
