Treatment of common duct stones in patients with atypical papillae using small endoscopic sphincterotomy and endoscopic balloon dilatation / 中华肝胆外科杂志

ABSTRACT

Objective To evaluate the effect of small endoscopic sphincterotomy and endoscopic balloon dilatation in the treatment of common duct stones (CDS) in patients with atypical papillae (combined with diverticula; after surgical operation; combined with abnormal duodenal lumen with no definite cause).MethodsOne hundred and three patients with CDS and with atypical papillae treated from July 2007 to March 2010 were randomly divided into three groups.Thirty-four patients received endoscopic sphincterotomy (EST group),34 patients received endoscopic balloon dilatation (EBD group) and the remaining 35 patients received small endoscopic sphincterotomy and endoscopic balloon dilatation (EST+EBD group).The general state of the patients in the 3 groups showed no significant difference (P＞0.05).We tried to remove all CDS using baskets and/or balloons after the procedures on the papillae.In some patients the stones were crushed by using a basket mechanical lithotriptor (BML).In some patients with huge stones,we could only placed in a plastic stent because of the high risk of removing the stones in a single procedure.ResultsSuccessful endoscopic retrograde cholangiopancreatography (ERCP) was carried out in 96 patients.Patients in the EST+ EBD group had less complications,especially hemorrhage,when compared with the EST group (P＜0.05).Also,the EST+EBD group had a significantly higher success rate of complete stone removal (P＜0.05),decreased use of BML (P＜0.05) and decreased rate of acute pancreatitis when compared with the EBD group (P＜0.05).ConclusionsThe success rate of ERCP in managing patients with CDS with atypical papillae remained high.Small endoscopic sphincterotomy and endoscopic balloon dilatation had a higher success rate of removing stones at the first attempt and a decreased rate of complications.
