Brief Summary:
Endoscopy is an established method of treatment for painful obstructive calcified pancreatitis. It involves the disintegration of calcifications using extracorporeal shock wave lithotripsy (ESWL) followed by endoscopic removal of stone fragments possibly associated with stent insertion. A pilot study suggests that ESWL alone relieves pain in calcified chronic pancreatitis (CP). The aim of this study is to compare both techniques in a randomized controlled trial.
