Floating pancreatic duct concrements in chronic pancreatitis. Pain relief by endoscopic removal.

This report describes 3 patients with chronic relapsing pancreatitis, floating pancreatic duct concrements between 4 and 6 mm in diameter, moderate to advanced ductal changes, and repeated severe attacks of pain during acute relapses over a period of several months. Immediate relief of pain was achieved in all 3 patients by endoscopic papillotomy aimed at widening the main pancreatic duct and subsequent extraction or spontaneous passage of pancreatic duct concrements. On the basis of our experience with the patients presented here, endoscopic papillotomy widening the main pancreatic duct may be useful in some patients with chronic pancreatitis and floating pancreatic duct concrements.
