Stones in 98 patients wereexcluded spontaneously after endoscopic therapy. 207patients were subjected to basket or balloon stone ex-traction. Stones in 14 patients were discharged bybasket lithotripsy. Four patients were given wavelithotripsy. Stones in 22 of the 323 patients were ex-tracted thoroughly after 2-3 times attempts. Totalcomplications were noted in 2.5% of the patients.Hemorrhage from the gastrointestinal tract was seenin one patient, cholangitis in 4 patients, and pancre-atitis in 3 patients. In 92 patients receiving digestivetract barium X-ray examination, 86 developed nobarium reflux to the baliary tract, 2 pneumobilia, 4barium reflux to the biliary tract.Conclusion: EST and EPBD are relatively safe and effec-tive in treatment of choledocholithiasis, and have fewcomplications.展开更多
