title: Intraoperative removal of pancreatic duct calculus with a rigid ureterorenoscope and ultrasonic lithotripsy.
abstract: A 51-year-old man with chronic relapsing pancreatitis and recurrent episodes of acute attacks had an impacted ductal stone deep in the head of the pancreas. A staghorn calculus, 1 cm in diameter, was successfully disintegrated and removed intraoperatively with use of a visual endourologic technique and ultrasonic lithotripsy. Because of a dilated pancreatic duct and pseudocyst formation near the tail of the pancreas, distal pancreatic resection and longitudinal pancreaticojejunostomy were performed. Postoperatively, no pancreas irritation has been verified, and the patient has remained without symptoms.
