Dieulafoy lesion of the gallbladder: A rare cause of hemobilia and acute pancreatitis – Case report

Résumé fourni par la source

INTRODUCTION: Dieulafoy lesion of the gallbladder is very rare. It can cause hemobilia and, consequently, acute pancreatitis. After extensive research, the authors found six reported cases of this entity, none of them presenting as acute pancreatitis. CASE PRESENTATION: A 78-year-old woman presented to the emergency department a right upper-quadrant pain and nausea. Abdominal ultrasound showed a gallbladder full of a heterogenic content with no signs of lithiasis or acute cholecystitis. Blood lipase was significantly elevated. She was admitted for acute pancreatitis. During hospitalization she developed jaundice and hematemesis requiring blood transfusion. The upper gastrointestinal (GI) endoscopy with side-view duodenoscopy showed blood through the papilla of Vater. Computed tomography and magnetic resonance imaging confirmed the content of the gallbladder with no changes in the biliary tree. A laparoscopic cholecystectomy with intraoperative cholangiogram was performed. Histology revealed a Dieulafoy lesion. The patient was discharged three days after surgery and had no subsequent episodes. CONCLUSION: Hemobilia should be considered as a cause of upper GI bleeding and acute pancreatitis, especially if both are concurrent. Treatment is directed to the cause, with bleeding control and restoration of bile flow, which can be accomplished by a single minimally invasive surgery.
