[Pancreaticolithiasis and pancreatic pseudocysts--interventional therapy].

Interventional (non-surgical) therapy is a relative new approach in the management of chronic pancreatitis. Indications for endoscopic therapy are pseudocysts and strictures or stones of the main pancreatic duct. Endoscopic sphincterotomy, extraction of pancreatic duct stones, extracorporal shock-wave lithotripsy (ESWL), pancreatic duct stenting and drainage of pseudocysts are all methods with a high success rate but with a low complication rate. Therefore in patients with chronic pancreatitis and with a failure of conservative management interventional techniques have to be considered. They may be an alternative to surgical procedures.
