Title:Sequential algorithm analysis to facilitate selective biliary access for difficult
biliary cannulation in ERCP: a prospective clinical study
Version:1Date:21 January 2014
Reviewer: Jens Tischendorf
Reviewer's report:
This is a nice prospective study about a sequential algorithm for biliary access in
ERC. This study has severeal limitations, that were all appropriately discussed by
the authors. To my opinion, there are only 2 minor remarks:
1. What is the reason to do in all patients CT/MRT instead of endoscopic
ultrasound (EUS) ?
2. In figure 1 the success rate of "double wire canniculation" is given. Howover,
the success rate of the other techniques is not stated. This is not consistent.
Level of interest: An article of importance in its field
Quality of written English: Acceptable
Statistical review: No, the manuscript does not need to be seen by a statistician.
