Title: Factors associated with patency of self-expandable metal stents in malignant biliary
obstruction
Version: 2 Date: 24 Apr 2023
Reviewer:  Katsuya Kitamura
Reviewer's report:
This paper examines SEMS patency factors for malignant biliary obstruction. Unfortunately,
this paper does not contain any new findings. Detailed studies have already been reported for
each site of biliary obstruction and for each tumor. Are these all the results of a single SEMS
placement across the papilla?
