Abstract

Abstract: Rationale: Gallbladder cancer is the most common malignancy of the biliary tree. Despite this, the only curative therapy remains surgical resection of the lesion achieving microscopically clear margins before malignant spread has occurred. Gallbladder duplication is an uncommon anatomical variance which occurs globally. It can present in a range of ways dependent on the embryological origin of the variance. Case: A 52-year-old female presented for planned laparoscopic cholecystectomy in the context of cholelithiasis resulting in recurrent biliary colic. The patient had no personal history of malignancy or significant medical comorbidities. Diagnosis: Intraoperatively, the patient was found to have Y-insertion variation of gallbladder duplication. Histopathology of the resected gallbladders showed an incidental invasive gallbladder adenocarcinoma affecting one of the gallbladders. Intervention: Both gallbladders were laparoscopically resected en-bloc. Outcomes: The patient underwent oncology staging, which found no evidence of metastatic spread. Regular surveillance is attended with no recurrence of disease identified. Conclusion: There are few reported cases detailing the occurrence of gallbladder adenocarcinoma in the presence of duplication of the gallbladder. This case demonstrates the clinical benefit of R0 surgical resection of gallbladder cancer, whilst highlighting the difficulties of diagnosing duplication of the gallbladder or gallbladder adenocarcinoma.
