We report on the case of a 50‐year‐old woman with idiopathic chronic calcifying pancreatitis and diabetes. An endoscopic retrograde pancreatography showed a stone with a diameter of 23 mm and multiple small stones in the head of the pancreas. An endoscopic pancreatic sphincterotomy was performed. However, the stone could not be removed endoscopically. So we performed an extracorporeal shock wave lithotripsy (ESWL) using a Tripter X1. The stone was located in the shock wave focus by fluoroscopy. Under intravenous sedation, the patient received 5 ESWL sessions (a total of 11700 shock waves with an energy of 18kv). ESWL permitted stone disintegration and successful endoscopic extraction of the fragments. Complete clearance in the main pancreatic duct was achieved. No severe complications were observed. After treatment, an improvement in the PFD test was seen. ESWL is an effective method for treatment of endoscopically unextractable pancreatic ductal stones.
