A 44‐year‐old man was admitted to hospital because of sudden severe postprandial right epigastric pain. Abdominal echography showed multiple calculi in the gallbladder and evidence of a probable septum at the neck. Based on the results, tentative diagnoses were made of gallbladder calculosis with associated gallbladder curvature or malformation, and gallbladder adenomyomatosis. Preoperative endoscopic retrograde cholangiopancreatography (ERCP) revealed a duplicate gallbladder consisting of two cystic ducts with two connected gallbladders. Laparoscopic cholecystectomy (Lap‐C) was performed. Inflammation of the Calot's triangle was mild. The two cystic ducts with one common bile duct were identified, and the cystic ducts separated by individual clipping. Duplicate gallbladder, a malformation of the gallbladder, has been reported to occur at an incidence of 0.02%. To date, a total of 60 cases have been reported in Japan, and recent cases have been treated with Lap‐C. In the present case, the surgery could be safely performed because the bifurcation of the cystic ducts could be identified by preoperative ERCP. |
