PEER REVIEWER COMMENTS: 
GENERAL COMMENTS: In the revised manuscript the authors made he
changes according to the reviewers' suggestions. 
In the answers to reviewers they explained some points of discussion, or things
not clear in the previous version
REQUESTED REVISIONS: 
- one of the reviewers suggested to delete the term "first" case. This was not
done in the manuscript at line 45
- line 110: " that 4 cm of the bile duct remained after surgery". What does it
mean this sentence? Were the authors thinking to the cystic duct instead?
- too much discussion in the paper is about the low insertion of the cystic duct ,
and that it runs parallel to the bile duct. Although this option can generate some
difficulties to ERCP, it is a well know condition, not extremely rare. The authors
should reduce the information and discussion about this topic
ADDITIONAL REQUESTS/SUGGESTIONS: 
As already stated before"
