Double trouble--duplication of the gallbladder requiring repeat laparoscopic cholecystectomy.

Duplication of the gallbladder is a surprisingly common phenomenon. Clinically, these patients present with straightforward gallbladder pathologies. It is a challenging preoperative diagnosis on ultrasound, and most cases are diagnosed intra-operatively. We present a case of gallbladder duplication, where the patient presented with biliary colic, had a straightforward laparoscopic cholecystectomy, and then represented with biliary colic four years later.
