Laparoscopic management of small bowel obstruction and ileo-ileal intussusception
Meckel’s diverticulum is the most common congenital anomaly of the digestive tract, found in 2 to 3% of the population. It is usually detected in children. In adults, symptoms vary, and diagnosis is therefore uneasy to establish. The most common infectious complications include obstructions and bleedings, which account for approximately one third of overall complications. Obstructions may be caused by intussusception or by a band.
This video demonstrates a case of a 49-year-old male patient, who necessitated an emergency surgical procedure for the management of a small bowel obstruction induced by the presence of Meckel’s diverticulum and intussusception. Due to an underlying necrosis, a resection and an anastomosis of the small bowel were performed.

Endoscopic internal drainage of gastric fistula after sleeve gastrectomy
Gastric fistula is a major adverse event after sleeve gastrectomy.
In this live instructional video, authors present the case of a 45-year-old woman with a complex postoperative course after sleeve gastrectomy due to a gastric leakage and a twisted stomach. The patient had already been managed with the endoscopic placement of a fully covered metal stent and a percutaneous drainage with no resolution of the fistula.
The first step of the procedure consists in the removal of a 16cm fully covered stent using a grasper. After contrast injection, the leakage and the gastric twist are visualized. Under fluoroscopic control, a 30mm pneumatic dilatation of the twist is obtained. Two double pigtail plastic stents are placed between the stomach and the abscess cavity in order to achieve internal drainage and facilitate the healing process. The percutaneous drainage will be removed one day after the procedure while the plastic stents will be removed after 3 months.

Laparoscopic cholecystectomy: cystic duct stone management
This video demonstrates a laparoscopic cholecystectomy in a 69-year-old woman who had multiple episodes of biliary colic. Ultrasonography and MRI showed the presence of multiple gallbladder stones. MRI also showed a folded gallbladder infundibulum over the cystic duct, which is enlarged and contains a stone. The common bile duct is otherwise perfectly thin and free of stones. In this video, one can observe a stepwise cholecystectomy technique, with exposure, dissection of the serosa and of Calot’s triangle. Cystic artery division is first performed in order to allow complete cystic duct dissection obtaining the critical view of safety. The dissection of the dilated cystic duct is thoroughly demonstrated. A small stone is pushed back into the gallbladder; the cystic duct is opened and checked for residual stones, and the cystic duct convergence with the common bile duct is evidenced prior to clip positioning and duct division.

LIVE INTERACTIVE SURGERY: robotic low anterior resection for a local recurrence of rectal cancer
In this live interactive surgery, Dr. Parra-Davila demonstrates a robotic low anterior resection for a local recurrence of transanally excised rectal cancer. The operative technique shown includes a robotic oncological ‘en bloc’ resection and intracorporeal anastomosis. In the patient’s history, an ulcerated villous polyp too large for endoscopic removal was addressed to surgery. Preoperative biopsies had failed to detect malignancy. The surgical procedure consisted in a transanal full-thickness resection including partial TME for lymph node sampling. Since the operative specimen revealed a pT2N1a (1/8) rectal adenocarcinoma, the patient underwent adjuvant radiochemotherapy. The following year, a single hepatic metastasis was resected, complemented by postoperative chemotherapy. After 7 years of uneventful follow-up, an anastomotic recurrence was diagnosed. Following oncologic committee discussion, the patient was advised to undergo surgery.

Laparoscopic appendectomy and fenestration of hemorrhagic ovarian cyst
This is the case of a 19-year-old female patient who was admitted to the emergency department for lower abdominal pain going on for 24 hours. No abdominal guarding was noted. Biological findings showed an inflammation with leukocytes at 16,000 and CRP levels at 112. CT-scan showed the presence of an enlarged appendix (9mm thick) along with a voluminous adnexal cyst, which may be suggestive of a tubo-ovarian abscess. Laparoscopic exploration is performed. Congestive appendicitis is confirmed, as well as the presence of a hemorrhagic right ovarian cyst. Laparoscopic appendectomy is performed and the hemorrhagic ovarian cyst is fenestrated.

Laparoscopic appendectomy for appendicitis with peritonitis
This is the case of a 37-year-old male patient who presented with abdominal pain and fever at 39.4°C. The work-up demonstrated important inflammation with leukocytes at 16,000 and CRP levels at 169. CT-scan confirmed an acute appendicitis with an appendicolith at the base. The appendix is probably perforated as the CT-scan also demonstrated a pneumoperitoneum. Laparoscopic appendectomy is decided upon. The operative set-up is standard with an optical port placed at the umbilicus, a port in the left iliac fossa, and a suprapubic port. Exposure, appendectomy with stapling of the appendicular base, and cleansing of the peritoneal cavity are thoroughly demonstrated.

Laparoscopic ileocecal resection for unresectable appendix
This is the case of a 36-year-old woman who has had an exploratory laparoscopy in another institution 2 months earlier. Acute appendicitis was suspected, based on ultrasound exam. However, exploration has shown an inflammatory appendicular mass, impossible to dissect. The patient was administered antibiotics for a period of 3 weeks. A laparoscopic appendectomy was decided upon at an interval of 2 months. Work-up included CT-scan and colonoscopy, which did not demonstrate anything specific.
Laparoscopic exploration demonstrated important fibrotic and scarry tissues around the appendix and the cecum. Despite painstaking dissection, appendectomy was impossible. Ileocecal resection was decided upon. Operative steps, namely exposure, division of the last ileal loop, division of the meso, division of the right colon above the ampulla coli and the intracorporeal side-to-side stapled anastomosis are demonstrated. Pathological findings evidenced an endometriotic nodule. The postoperative course was uneventful.

Laparoscopic Roux-en-Y gastric bypass after gastric band removal
This video demonstrates the case of a 50-year-old woman with morbid obesity (BMI of 39). She had a gastric banding placed 7 years before, which became ineffective 3 years after the primary surgery, resulting in band removal 2 years ago.
A secondary bariatric surgery was scheduled, with the decision to perform a laparoscopic Roux-en-Y gastric bypass. This video shows the surgical technique, with special emphasis on dissection of the cardia and lesser curvature, where the anatomy is altered as a result of the previous band. An interesting technical point occurs during the creation of the jejunojejunostomy, where a perforation of the biliary loop is accidentally made during the EndoGIATM linear stapler introduction.

Unintentional dissection of the common bile duct
This video demonstrates the case of an 81-year-old woman with chronic cholecystitis. She has had several episodes of right hypochondrium pain with altered liver tests, which spontaneously got back to normal values. Ultrasound and CT-scan demonstrated the presence of uncomplicated gallstones and a slightly hypotonic common bile duct (8mm in diameter). No obstacle was visualized in the common bile duct. A delayed laparoscopic cholecystectomy was scheduled. This video shows how some inaccuracies in the dissection technique and the presence of an altered anatomy have led to a circumferential dissection of the common bile duct. Common bile duct injury was avoided and the importance of an intraoperative cholangiography is emphasized.
