A 38-year-old male presented with painful obstructive jaundice. Ultrasound showed biliary dilatation and a duplicated gallbladder (DG). Magnetic resonance cholangiopancreatography (MRCP) imaging confirmed the diagnosis of DG and raised the suspicion of a stricture in the distal common bile duct. Endoscopic retrograde cholangiogram, sphincterotomy with small stone extraction, and biliary stent placement were accomplished, and the patient was transferred to our tertiary center. Given the report of a stricture, endoscopic retrograde cholangiopancreatography (ERCP) was repeated and showed no duct narrowing or persistent choledocholithiasis, but only one cystic duct and gallbladder filled. The patient subsequently underwent laparoscopic cholecystectomy using top-down technique with complete resection of both gallbladders. Postoperatively, the patient underwent another ERCP for elevated bilirubin due ampullary edema. Subsequently, his bilirubin normalized and he was discharged home on postoperative day 5. DG is a rare anatomical finding that may be associated with choledocholithiasis and cholecystitis. In this case, a combination of radiographic, endoscopic and laparoscopic procedures was utilized to resolve the patient's clinical problem.
