Secondary outcomes were overall survival (OS), incidence of recurrent biliary obstruction (RBO), causes of RBO, and adverse events (AEs).Results: The median time to RBO did not differ significantly between the MH-SEMS and PC-SEMS groups (318 vs. 460 days, p=0.17). Furthermore, the two groups did not differ significantly in terms of OS and incidence rate of AEs, including RBO and cholecystitis. RBO caused by tumor ingrowth was slightly more common in the MH-SEMS group (p=0.089). The MH-SEMS group had a slightly lower 12-month non-obstruction rate than the PC-SEMS group (33.9% vs. 60.9%). In the MH-SEMS group, stent removal was successful in all seven patients in whom it was attempted.Conclusions: The clinical outcomes of MH-SEMS and PC-SEMS were similar in patients with MDBO caused by pancreatic carcinoma were similar.<\/jats:p>","DOI":"10.5946\/ce.2024.340","type":"journal-article","created":{"date-parts":[[2025,8,26]],"date-time":"2025-08-26T09:10:22Z","timestamp":1756199422000},"page":"744-756","update-policy":"https:\/\/doi.org\/10.5946\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Efficacy
