Reviewer's report
Title:Endoscopic Inside stent placement is suitable as a bridging treatment for
preoperative biliary tract cancer
Version:3Date:27 July 2014
Reviewer: Toshio Tsuyuguchi
Reviewer's report:
Major
#1: Stent diameter is an important risk factor for stent obstruction. In patients with
inside group, 8.5Fr stent is used more frequently than 7Fr. On the contrary, 7Fr
stent is generally used in patients with conventional group. Authors should add
stent diameter data on risk factors (7Fr or more) for stent obstruction (Table 7).
#2: In conventional group, 4 patients without chemotherapy had long
preoperative period more than 60 days. Surprisingly, case 6 period is 448 days.
These cases are uncommon. Is there any selection bias that was not described
in this article?
Minor
#3: It is difficult to remove migrated inside-stents in patients with intact duodenal
papilla. It’s a weakness of inside-stent.
#4: “sphincter of Odd”
#5: English correction is necessary.
Level of interest: An article of importance in its field
Quality of written English: Needs some language corrections before being
published
Statistical review: No, the manuscript does not need to be seen by a statistician.
