Common bile duct polyp mimicking choledocholithiasis: a case report with laparoscopic transcystic management

Although polyps of the extrahepatic biliary system are rare, an awareness of their potential existence is important as they may closely mimic choledocholithiasis clinically and radiologically but require distinct measures for successful management. This report describes the presentation and successful laparoscopic transcystic management of this infrequently encountered condition. It also explores the literature and discovers the numerous potential presenting features of common bile duct calculi and the spectrum of possible management options.
