Title:Plastic or metal stents for benign biliary strictures: a systematic review
Version: 2Date:18 September 2009
Reviewer: Michel Kahaleh
Reviewer's report:
MAJOR
1-We appreciate the efforts in removing the CSEMS patients.
2-However I am concerned about the inability to provide sessions numbers in
each group and the inclusion of IH stricture or stricture of unclear locations.
Please remove all patients with IH and unclear locations strictures and restrict
the analysis to extrahepatic biliary strictures.
Also acknowledge in the discussion that metal stents provide less sessions than
plastic stents which might offset the cost in favor of the plastic stent group and
change your conclusion accordingly
3-Change the current tables by providing one table summarizing metal stents
and one table summarizing plastic stents
Level of interest: An article of importance in its field
Quality of written English: Acceptable
Statistical review: Yes, and I have assessed the statistics in my report.
Declaration of competing interests:
I have receive funding support from Boston Scientific,COnmed, Olympus, Cook
and ALveolus
