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

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.
