Lemmel syndrome, characterized by biliary and pancreatic duct obstruction secondary to a periampullary duodenal diverticulum (PAD), remains a rare and often overlooked diagnosis,which can lead to a variety of gastrointestinal and biliary complications. This condition is often associated with obstructive jaundice, intermittent abdominal pain, cholangitis,and pancreatitis,resulting fromthe mechanicalobstructionorcompression of the biliary and pancreatic ducts. The pathophysiology behind Lemmel Syndrome is thought to involve the anatomical diverticulum causing disruption in normal bile and pancreatic fluid flow, leading to secondary biliary stasis and inflammation.
The accuracy of diagnosis was made possible by multimodal imaging methods, such as ultrasound, magnetic resonance cholangiopancreatography(MRCP), and computed tomography (CT) with oral contrast.
Management of Lemmel Syndrome typically involves relieving biliary obstruction and addressing the diverticulum’s associated complications. Therapeutic approaches may include endoscopic interventions, such as sphincterotomy or stent placement, or surgical resection in more severe cases.
This case report aims to increase awareness of Lemmel Syndrome, emphasizing the importance of early recognition, accurate radiologic assessment, and appropriate management. Given the rarity of this condition, further research and clinical studies are needed to develop standardized diagnostic and treatment protocols, ultimately improving patient outcomes in individuals affected by Lemmel Syndrome.
