Title: The use of fully covered self-expandable metal stents in the endoscopic treatment of portal
cavernoma cholangiopathy An Original Article
Version: 1 Date: 21 Aug 2023
Reviewer's report:
Although this is an interesting paper reporting the efficacy of Fully covered self-expandable
metal stents for portal cavernoma cholangiopathy-related biliary strictures, it has some critical
issues.
1. The authors describe the design of this study as a single-center prospective observational
study, but is it a single-center retrospective observational study?
2. The authors state that they evaluated the outcomes of FCSEMS as initial treatment for PCC-
related biliary strictures, which is highly contradictory since 5 of the 12 patients were previously
and not initially treated.
3. The high incidence of cholecystitis due to FCSEMS placement in 7 of 12 patients (58.3%) is
unacceptable, even though five patients improved with conservative treatment.
