Question: A 46-year-old man with a 3-month history of recurrent pancreatitis of unknown etiology was admitted for another episode of acute pancreatitis. Liver function tests (LFTs) at the time of initial presentation showed elevated bilirubin (4.5 mg/dL) and transaminase levels >200 U/L. CT scan and MR cholangiopancreatography (MRCP) revealed pancreatic inflammation, gallbladder wall thickening, and 0.9 cm common bile duct (CBD) dilatation. He underwent endoscopic retrograde cholangiopancreatography (ERCP) with biliary sphincterotomy and sludge removal (Figure A).
