Over the last few years, a new method, neither medical nor surgical, has been developed for treating often difficult-to-treat chronic pancreatitis. In the case of obstructive pancreatitis, endoscopy permits both drainage and calculus extraction. Even encrusted concrements and calcifications can be removed from the pancreatic duct with the aid of extracorporeal shockwave lithotripsy. The first aim is to relieve pain by restoring a free flow of secretion. Perhaps the use of endoscopic treatment in the early stages will break the vicious circle of chronic inflammation and ultimate gland destruction.
