Laparoscopic trans-cystic common bile duct stone retrieval in a patient with gallbladder agenesis

摘要

Gallbladder agenesis is a rare but well-documented anatomical variation. Pre-operative diagnosis may be difficult as patients can present with typical symptoms of biliary colic and imaging may be misleading. We report a case of choledochoscopy and common bile duct stone retrieval in a patient found to have agenesis of the gallbladder intra-operatively.
