LEMMEL´S SYNDROME: CASE REPORT

Abstract

Lemmel syndrome (LS) is a rare clinical entity causing obstructive jaundice resulting from obstruction of the intrapancreatic common bile duct by a periampullary duodenal diverticulum, with consequent dilation of the intrahepatic and extrahepatic bile ducts. In this article, we describe the case of a 71-year-old female patient who was correctly diagnosed with Lemmel syndrome through laboratory and imaging tests performed after hospital admission due to symptoms such as nausea, anorexia, abdominal pain and diarrhea. Because it generates nonspecific symptoms, the diagnosis of this pathology can represent a challenge for the physician. The imaging test considered the gold standard for the identification of LS is endoscopic retrograde cholangiopancreatography (ERCP), and the treatment of choice is conservative. Despite its rarity, it is essential that physicians consider Lemmel Syndrome as a differential diagnosis in cases of obstructive jaundice to ensure early and correct treatment and prevent the development of complications.
