ABSTRACT

Objective To evaluate the efficacy and safety of endoscopic sphincterotomy(EST)in treating common bile duct stone or strictive papillitis,and then analyze possible related risk factors for long-term complications after EST.Methods We made a retrospective study of 103 out of 158 patients who had EST from January 2005 to December 2006.Results In the 103 patients,there were 13 cases of long-term complications(≥3 m after EST),the incident rate being 12.6%recurrent calculus of common bile duct in 8 cases,combined cholangitis in 6;cholangitis in 1;acute calculus cholecystitis in 2;residual calculus in 1 case;chronic pancreatitis in 1 case.Conclusion Endoscopic papillosphincterotomy is an effective and safe way to treat biliary tract obstruction.Preoperative jaundice may be the risk factor inducing long-term complications after EST.
