Lemmel syndrome

Dr Aditya Shetty et al.

Lemmel syndrome is defined as an obstructive jaundice caused by a periampullary duodenal diverticulum (of the second part of the duodenum) compressing the intrapancreatic part of common bile duct with resultant upstream dilatation of the extra- and intrahepatic bile ducts.

Patients may present with recurrent episodes of jaundicepancreatitis and/or cholangitis.
