Title: The utility of self-expanding metal stents in benign biliary strictures- a retrospective case
series
Version: 1 Date: 26 Jul 2023
Reviewer's report:
Thank you for the opportunity to review this manuscript.
In this study, the authors retrospectively examined cases in which self-expandable metal stent
(SEMS) was placed in the benign biliary stricture (BBS).
A high frequency of complications was observed, and whether SEMS placement in the BBS was
effective and safe is unclear. This manuscript seems to be not suitable for publication.
#Why are baseline patient characteristics not shown in this manuscript? There are 31 enrolled
patients, and a table of characteristics may be shown. Moreover, if the results are statistically
analyzed, they should be presented in tables.
#Despite stent migration occurring in 20.9% of patients, the authors concluded that SEMS
placement in the BBS is safe. A stray metallic stent is difficult to remove, and metallic stent
placement in the BBS is not safe.
#To demonstrate the effectiveness and safety of metallic stents for BBS, it should be compared
with a group in which a plastic stent was implanted.
#Retrograde infection in the bile duct is considered to be a major cause of cholangitis. Retrograde
cholangitis is more likely to occur if the stent protrudes from the papilla. Therefore, stent
placement has a significant impact on the study results; what was the stent’s position?
