Resumen

Lemmel syndrome is a rare entity that causes biliary obstruction due to compression of the common bile duct by a peri-ampullary diverticulum. It can manifest as acute cholangitis and is often underdiagnosed. However, once identified, it can be successfully treated with endoscopic retrograde chol-angiopancreatography, being one of the most used methods. Lemmel syndrome should be considered in elderly patients with a diagnosis of periampullary duodenal diverticulum, once the presence of choledocholithiasis and pancreatobiliary neoplasms have been ruled out.
