[Intraoperative, endoscopic lithotripsy of pancreatic duct calculi. A contribution to the surgical treatment of chronic calcifying pancreatitis].

The problem of chronical calcifying pancreatitis is demonstrated in two female patients. Resection of the pancreas is necessary, if prepapillar concrements cannot be extracted. By two new techniques, ultrasound-lithotripsy and laser-induced shock-wave-lithotripsy, it is possible to destroy concrements and to remove them. These new techniques are now used primarily in surgery.
