Case Report: Endoscopic Removal of an Eroded Gastric Band Causing Small Bowel Obstruction upon Migration into the Proximal Jejunum.

Obes Surg 2020 Dec 11;30(12):5153-5156. Epub 2020 Aug 11.

Department of Minimally Invasive and Bariatric Surgery, Hôpital du Sacré-Coeur, CIUSSS du Nord de l'île de Montréal, 5400 Boulevard Gouin Ouest H4J 1C5, Québec, Montréal, Canada.

Background: Adjustable gastric banding (AGB) is on the decline due to its relatively modest amount of expected weight loss, coupled with high rates of revision and complications such as band erosion. Management of eroded gastric bands can be challenging especially when complete intra-gastric erosion is followed by distal migration causing small bowel obstruction.

Methods: We present an endoscopic option of using a pediatric colonoscope to remove an eroded AGB causing jejunal obstruction.

Result: Endoscopic removal of an eroded ABG causing bowel obstruction was successful.

Conclusion: Endoscopy remains a safe and relatively non-invasive approach to deal with such complications.

Imaging appearance on CT post laparoscopic Roux-en-Y gastric bypass using bioabsorbable prosthesis with fibrin glue fixation to prevent a Petersen's space hernia.

BJR Case Rep 2019 Sep 9;5(3):20180111. Epub 2019 Apr 9.

Department of Surgery, St George Private Hospital, Sydney, Australia.

Imaging post bariatric surgery is becoming more common over the past decade due to increasing incidence of obesity in the population and subsequent treatment. In recent years, the use of topical haemostatic agents and bioabsorbable prostheses has increased leading to higher likelihood of encountering these agents on post-operative imaging. Imaging in the post-operative period is occasionally performed to assess for complications such as obstruction, leak and abscess formation. Familiarity with these agents is crucial in preventing incorrect diagnosis. Laparoscopic Roux-en-Y gastric bypass (RYGB) is favoured over the open approach as it is safer and more effective, with a mortality rate of 0.5% and morbidity around 7-14 %. The main cause of late post-RYGB complications is the development of internal hernias such as a Petersen's hernia. During the procedure, a space between the alimentary loop of the small bowel and the transverse mesocolon is created and is called the Petersen's defect. Subsequently, a part of the small bowel can herniate through this orifice. As this operation is becoming more common, the incidence of internal herniation has been increasing. This case report describes a new bariatric surgical technique and the associated post-operative radiological appearances on CT. The surgical technique has been pioneered in Sydney, Australia and involves a laparoscopic RYGB using bioabsorbable prosthesis with fibrin glue fixation to prevent a Petersen's space hernia.

Retained gallbladder secondary to retrieval bag rupture during laparoscopic cholecystectomy-A case report.

Int J Surg Case Rep 2019 9;59:101-106. Epub 2019 May 9.

Faculty of Medicine, University of New South Wales, Sydney, Australia; St George Private Hospital, Kogarah, New South Wales, Australia.

Introduction: Retrieval bags are used in laparoscopic cholecystectomies to reduce the risk of bile and gallstone spillage during removal of the gallbladder. Retrieval bag rupture is rare, and its complications have never been previously documented.

Presentation Of Case: A 17-year-old female presented three months post-laparoscopic cholecystectomy with a tender periumbilical mass. Her operative report noted difficulty removing the retrieval bag from the infra-umbilical port site. Imaging of the lump revealed an intra-abdominal fluid collection communicating with the umbilicus. A diagnostic laparoscopy uncovered significant pus in the peritoneal cavity and a gallbladder remnant with multiple gallstones. A combination of sharp and blunt dissections was used to free the gallbladder remnant from its adherent surroundings for removal. A peritoneal washout was performed following extraction of the retained gallstones. The patient's presentation could be traced back to her laparoscopic cholecystectomy where it was confirmed that the retrieval bag ruptured during removal. This would have transected the gallbladder, causing its remnants and associated gallstones to be retained in the peritoneal cavity.

Discussion: Retrieval bag rupture can result in retained gallbladder remnants in the peritoneal cavity. Abdominal abscess can manifest months after the initial operation.

Conclusion: Retrieval bags should be inspected following removal to ensure it is completely intact. Surgeons should consider extending the fascial incision if there is any difficulty during removal. Any damage to the retrieval bag mandates immediate pneumoperitoneum for further exploration of retained products. Governance bodies should incorporate practice guidelines related to retrieval bag rupture as these are currently not present.

Novel technique using a bioabsorbable prosthesis with fibrin glue fixation to prevent a Petersen's space hernia.

J Surg Case Rep 2017 Dec 15;2017(12):rjx246. Epub 2017 Dec 15.

Introduction: Laparoscopic Roux-en-Y gastric bypass is a bariatric operation that is effective for long-term weight loss. Although rare, one serious complication is an internal hernia through Petersen's space, which may result in bowel strangulation. Although the incidence of internal hernia can be reduced through closing the Petersen's defect, it does not eliminate the risk. This case describes a novel and reliable method to close Petersen's defect. We report the case of a 30-year-old female who underwent a laparoscopic Roux-en-Y gastric bypass for the management of morbid obesity. Following her Roux-en-Y reconstruction, a prosthetic bioabsorbable mesh was placed in Petersen's space and reinforced with fibrin glue to prevent internal herniation through Petersen's defect. The use of a bioabsorbable mesh in Petersen's space is a novel and easy technique that could be used to reduce the incidence of an internal hernia through Petersen's defect.
