Lemmel syndrome is created by a periampullary duodenal diverticulum. It is identified incidentally in 22% of the population, <10% present with jaundice, pain in the right flank and alteration of bilirubins, transaminases and/or pancreatic enzymes. Its diagnosis and therapeutic management can be carried out successfully with endoscopic retrograde cholangiopancreatography (ERCP), although some cases will require surgical management. We present the case of a 72-year-old male with recurrent obstructive jaundice and suspected choledocholithiasis managed with ERCP, identifying Lemmel syndrome. We recognize the importance of considering this extraordinary cause of obstructive jaundice in order to be able to make a diagnosis and offer timely treatment.
