膵石嵌頓に起因する急性胆管炎・膵炎に対して緊急内視鏡的膵石除去術が有用であった 1 例

A 73-year-old man who was regularly followed up for alcoholic chronic pancreatitis accompanied by main pancreatic duct stones presented with sudden-onset persistent epigastric pain while at home. CT revealed a pancreatic stone (10mm) in the papilla of Vater and common bile duct and main pancreatic duct dilatation at the site of the initial obstruction. The patient was diagnosed with obstructive jaundice, acute cholangitis, and acute pancreatitis secondary to an incarcerated pancreatic stone. Immediate ERCP revealed an ivory white pancreatic stone at the pancreatic duct orifice. The patient underwent emergency endoscopic pancreatic sphincterotomy and stone removal using a balloon catheter, which led to symptom resolution.
