Title: Factors associated with patency of self-expandable metal stents in malignant biliary
obstruction
Version: 2 Date: 12 Apr 2023
Reviewer's report:
This is a single-center, retrospective, observational study of factors associated with SEMS
patency in malignant common bile duct obstruction. However, the results of this study cannot
be generalized because the survival time of the subject group is too short of examining
factors associated with SEMS patency. Primary cancer and the type of SEMS used are also
hetrogenous.No new findings can be drawn from this study, as there are previously published
reports of better study designs.
