Title: Risk Factors for Adverse Events Associated with Endoscopic Retrograde
Cholangiopancreatography in Patients with Surgically Altered Anatomy: a Retrospective Study
Version: 1 Date: 01 Oct 2021
Reviewer's report:
1. Suggest to clarify the definition of multiple cannulation attempts (? >5 attempts or >5 minutes
which are usually used to define difficult canulation).
2. Most of the reconstructed anatomy in this study are Bilroth I and Bilroth II reconstruction
(~80%). This is likely the reason why most ERCP can be performed using conventional
endoscope instead of DAE in this series. The low percentage of patients with Roux-en-Y
anatomy in this series may be one of the reason for high technical success rate.
