Lemmel syndrome is a rare clinical entity characterised by the presence of a periampullary duodenal diverticulum leading to compression and dilatation of the common bile ducts, accompanied by obstructive jaundice. In a small percentage of cases, it may be associated with pancreaticobiliary complications such as cholangitis or acute pancreatitis, and there are no standardised approaches to its treatment. We present a case of Lemmel syndrome in a 53-year-old woman presenting with angiocholitis and acute pancreatitis successfully treated with ERCP.
