Title: Feasibility, effectiveness, and safety of simultaneous side-by-side deployment of
uncovered self-expandable metal stents for malignant hilar biliary obstruction: a retrospective
single- center study
Version: 0 Date: 30 Aug 2024
Reviewer:  Zhaohui Tang
Reviewer's report:
By observing the feasibility, effectiveness and safety indexes of simultaneous side-by-side
deployment of uncovered self-expandable metal stents, the paper concludes that this technique is
a promising choice. The author made a good choice of evaluation indicators for security, which
solved most of my doubts. I think there are still the following things that need to be revised
before publication:
1.Mere retrospective observation is difficult to fully explain the problem. The authors should
consider whether there are differences between the indicators of complementary simultaneous
and traditional side-by-side deployment
2.Authors should consider describing the procedure in more detail, highlighting some of the
technical points in order to provide a single-center experience for repeating and optimizing the
technique
3.Some references are outdated and authors should consider updating them
