Duplication of gallbladder: A rare congenital malformation

Gallbladder duplication is a rare anatomic malformation, which can now be detected by preoperative imaging study. We report a case of a symptomatic duplicated gallbladder, successfully treated by laparoscopic cholecystectomy. This anomaly is important for surgeons to know because of the associated anatomical variations of the main bile duct and hepatic artery and increased risk of common bile duct injury.
