ABSTRACT
Objective To determine the safety and clinical value of secondary ERCP to a failed intubation procedure.Methods A total of 212 patients with difficult intubation during ERCP procedures were enrolled.Patients with failed conventional intubation accepted precut sphincterotomy.The operation stopped after one hour of effort.A secondary selective ERCP was performed at a appropriate time.The operation success rate and complication rate of first ERCP and secondary ERCP were compared.Results The success rate of first ERCP was 67.0％ (142/212),and the total success rate was 90.6％ (192/212).The total success rate is significantly higher than that of first ERCP operation(x2 =35.263,P ＜0.05).The complication rate of first ERCP,secondary ERCP and total complication rate was 8.96％ (19/212),4.29％ (3/70),10.38％ (22/212),respectively.Complication rates of total ERCP and secondary ERCP were not significantly different from the first ERCP (P ＞ 0.05).Conclusion It is safe and effective for patients with failed ERCP intubations after precut to receive a secondary ERCP at a appropriate time.
