Title:Endoscopic large-balloon dilation alone versus endoscopic sphincterotomy
plus large-balloon dilation for the treatment of large bile duct stones
Version: 1Date:19 November 2012
Reviewer: Jong Ho Moon
Reviewer's report:
Major points
1. It seems that the initial ballooning conditions are important in this procedure.
Was the gradual inflation time to disappearance of the waist same in both group?
Does it need more slowly inflation in EPLBD without sphincterotomy group?
Please, give more detail description about the gradual inflation until the
disappearance of the waist, especially in only EPLBD group.
2. Ballooning size was selected according to the sizes of the stones and bile
duct. In result, authors showed maximum transverse diameter of the bile duct in
table 1. However, the diameter of the distal CBD directly affected with EPLBD is
more important in the selection the size of balloon. Practically, table 1 and 2
show difference between bile duct size and the diameter of inflated balloon.
Please provide the diameter of distal CBD in both groups.
Minor points
1. In discussion section, authors describe that EPLBD without sphincterotomy
may be associated with a lower risk of postprocedure bleeding. However, there is
no sufficient data for this description. What do you think about it?
2. Authors defined the technical success as complete removal of all CBD stones
after EPLBD without the need for mechanical lithotripsy. However, there are no
descriptions about the technical success rate in result section. Maybe it means
complete stone removal without ML. It seems to be need of consistant
description in the article.
Level of interest: An article whose findings are important to those with closely
related research interests
Quality of written English: Acceptable
Statistical review: No, the manuscript does not need to be seen by a
statistician.
Declaration of competing interests:
I declare that I have no competing interests for this article.
