Title:Percutaneous Transhepatic Biliary Drainage Assisted by Real-Time Virtual
Sonography
Version: 2Date:24 May 2013
Reviewer: Andreas Weber
Reviewer's report:
The study demonstrated that accurate puncture of targeted bile ducts can be
achieved by performing RVS-assisted PTBD. Major limitations of the study are
the small number of patients and its retrospective nature.
Major Compulsory Revisions
The title should be clearly stated that this is a retrospective study
Minor Essential Revisions
It would be favourable to compare these data with a control group (conventional
procedure).Do you have these data?
Level of interest: An article of importance in its field
Quality of written English: Needs some language corrections before being
published
Statistical review: Yes, but I do not feel adequately qualified to assess the
statistics.
