Laparoscopic management of 'Y-shaped' gallbladder duplication with review of literature.

Gallbladder duplication is a rare congenital malformation that occurs in about 1:4000 cases. Congenital anomalies of the gallbladder and anatomical variations of their position are associated with an increased risk of complications during laparoscopic cholecystectomy. We report a case of gallbladder duplication with symptomatic cholelithiasis, who presented with recurrent episodes of biliary colic and subsequently underwent laparoscopic cholecystectomy with intraoperative cholangiography.
