Introduction Duplication of the gallbladder (GB) is a very rare surgical encounter affecting 1 in 4000–5000 population that often eludes detection on preoperative ultrasonography, and might increase operative difficulty and risk. The H-type anomaly is the most common whereby each GB drains into the common bile duct via a separate cystic duct. Presentation of case We report a young female patient with symptomatic gallstones who was incidentally found to have abnormal biliary anatomy on a CT colonography and an H-type duplication of the GB on MRCP. A challenging laparoscopic double cholecystectomy was performed uneventfully. Discussion Gallbladder duplication can be classified as a type-I anomaly (partiality split primordial gallbladder), a type-II anomaly (two separate gallbladders, each with their own cystic duct) or a rare type-III anomaly (triple gallbladders draining by 1–3 separate cystic ducts). Such anatomical variations are associated with increased operative difficulty and risks, including conversion to open cholecystectomy and common bile duct injury. Conclusion A young female patient was pre-operatively diagnosed with a Harlaftis's type-II GB anomaly. Each gallbladder was drained by a distinct cystic duct (H-type anomaly). A laparoscopic cholecystectomy was performed with no complications afterwards. Awareness of this rare anomaly might require intraoperative cholangiography when initially suspected during a cholecystectomy to facilitate anatomical recognition and avoid missing a symptomatic pathologic GB and the need for a repeat cholecystectomy.
