ABSTRACT

Objective To observe the clinical effect of small endoscopic sphincterectomy (SES) combined with endoscopic papillary balloon dilation (EPBD) in the treatment of large common bile duct stones.Methods The patients were randomly divided into 3 groupsnormal endoscopic sphincterotomy(EST),EPBD,SES combined with EPBD.The incidence of pancreatitis at 1 week after operation and the recurrence rate of inner duct stone within 15 months after operation were statistically analyzed.Results At 1 week after treatment,the incidence of pancreatitis was lower in group EST and group SES combind with EPBD than in group EPBD [3.3％ (1/30),3.3％ (1/30) vs.20.0％ (6/30),both P＜0.05].After 15 months of treatment,the recurrence rate of inner duct stone were lower in group B and group C than in group A 3.3％ (1/30),3.3％ (1/30) vs.23.3％(7/30),both P＜0.05).Conclusions In the treatment of large common bile duct stones,SES combined with EPBD can reduce the incidence of postoperative acute pancreatitis and the longterm recurrence rate of common bile duct stones.
