One of four trainees [200-400 cases of endoscopic retrograde cholangiopancreatography(ERCP)] supervised by a specialist(> 10000 cases of ERCP) performed the procedures. The success and complication rates associated with EST in each group were examined.RESULTS: Of the 87 patients with ASC, 59 were in the immediate EST group and 28 in the elective EST group. EST was successful in all patients in both groups. There were no complications associated with EST in either group of patients, although white blood cell count, C-reactiveprotein, total bilirubin, and serum concentrations of liver enzymes just before EST were significantly higher in the immediate EST group than in the elective EST group.CONCLUSION: Immediate EST can be as safe as elective EST for patients with ASC associated with choledocholithiasis provided they are not under anticoagulant therapy, or do not have a coagulopathy or a platelet count < 50000 × 103/μL. Moreover, the procedure was safely performed by a trainee under the supervision of an experienced specialist.展开更多
