Case Discussion

Case of Lemmel syndrome, one of the rare causes of obstructive jaundice. 

A careful examination is required to diagnose this condition. A small diverticulum could be missed. A thorough understanding of the biliary anatomy is required. An ideal method would be to trace the common bile duct to its distal opening to detect the cause of narrowing.
