Doudenal Diverticulum Revealed by an Episode of Acute Pancreatitis: A Case Study

Duodenal diverticulum is a common anatomical finding that is usually asymptomatic but may occasionally cause biliopancreatic complications, including acute pancreatitis. We report the case of a 48-year-old patient who was initialy operated for gallbladder sludge and underwent laparoscopic cholecystectomy. Postoperatively, she developed recurrent epigastric pain associated with elevated serum lipase levels. Computed tomography confirmed mild acute pancreatitis (Balthazar stage A). Magnetic resonance cholangiopancreatography and contrast-enhanced computed tomography after oral contrast ingestion revealed a small duodenal diverticulum in close contact with the second portion of the duodenum and the common bile duct, confirming the diagnosis. Conservative management resulted in a favorable outcome. This case emphasizes the importance of considering duodenal diverticulum as a rare etiology of acute pancreatitis when common causes are excluded.
