The investigators hypothesized that nipple balloon dilatation could make ERCP more successful and reduce postoperative complications and mortality. So the investigators design this experiment on this assumption.
The incidence of periampullary diverticula in patients with choledocholithiasis is very high at 47.1%. A large number of literatures refered that duodenal papillary diverticulum is a high risk factor for postoperative complications and recurrence of choledocholithiasis . Till now, there have been no randomized controlled trials to explore the effect of nipple balloon dilatation (EPLBD) on the treatment and prognosis of patients with choledocholithiasis complicated with periampullary diverticula (found during ERCP).
