Abstract: Objective To investigate the therapeutic efficacy of endoscopic sphincterotomy (EST) for treatment of choledocholithiasis. Methods The clinical data of 326 patients receiving EST from July 1990 to January 2009 were retrospectively analyzed. Long-term follow-up was performed in 195 of the 326 patients. Results The common bile duct stones were removed in 301 cases (92. 33%).The occurring rate of complications after EST was 6.13% (20/326). Of the 20 patients, 10 had pancreatitis (3.07%), 7 hemorrhage (2. 14%), 4 cholangitis (1. 220%) and 1 duodenal perforation (0.09%). Only 1 patient died. The follow-up showed that 20 patients had reflux cholangitis and 18 recurrence of common bile duct stones. Conclusion Therapeutic endoscopy is safe and effective for treatment of choledocholithiasis.
