ObjectiveTo investigate the value of endoscopic sphincterotomy (EST) on treating sphincter of Oddi dysfunction (SOD). MethodsForty-two patients with SOD according to Rome Ⅱ diagnostic criteria were retrospectively summarized. Bile duct residual stone, tumor or biliopancreatic duct obstruction diseases were excluded by B ultrasound, CT, and MRCP examination. Total 42 patients underwent EST. ResultsEST was done successfully in 42 cases, success rate was 100%. Postoperative acute pancreatitis occurred in 5 patients (11.90%), which were cured by 3-7 d conservative treatment. There were no complications of severe acute pancreatitis, digestive tract perforation, hemorrhage, and cholangitis. Follow-up 12-45 months (mean 23.8 months), symptoms of abdominal pain in all cases were improved or relieved, the effective rate was 100%. There were 2 cases treated conservatively because of hyperlipemic pancreatitis. ConclusionEST has become the primary treatment procedure for SOD because of definite outcome, less suffering, safety, less complications, and reproducibility, which are concordant with the requirements of minimally invasive surgery.
