Endoscopic treatment of pancreatic stone and pancreatic ductal stricture in chronic pancreatitis

摘要

I reviewed usefulness of endoscopic treatment for pancreatic stone and pancreatic ductal strictures. The complete stone-clearance rate after ESWL alone or in combination with interventional endoscopy was reported as 76 to 88%, and symptom relief was achieved in 93 to 100%. However, long-term prognosis after removal of pancreatic stones is still unknown. High rate of stone recurrence is another problem, and pancreatic ductal stricture may influence it. Pain relief rate by pancreatic stenting is reported as 74 to 94%. In addition, pancreatic stenting is useful as assistance of stone clearance by ESWL, and expected as prophylaxis of stone recurrence. More number of patients is necessary to make sure the usefulness of pancreatic stenting.
