Endotherapy for chronic pancreatitis with intracanalar stones.

Endotherapy for pancreatic stone is an emerging specialty. The judicious application of extracorporeal shock-wave lithotripsy (ESWL) and endoscopic retrograde cholangiopancreatography (ERCP) in selected groups of patients has increased the success rates of endotherapy, with excellent long-term results. In this review the authors share their vast experience of treating patients with pancreatic stones. The article will focus on the basic principles of pancreatic endotherapy, the instrumentation required, details of the ESWL technique and its applications, as well as the limitations, success rate, and complications of endotherapy in selected patients.
