Retrospective cohort study shows multi-hole stents improve outcomes in patients with malignant biliary obstruction, indicating better efficacy.

Multi-hole self-expandable metallic stents significantly improve drainage outcomes in patients with malignant biliary obstruction.
Patients receiving multi-hole stents had better success rates compared to those with partially covered stents in treating pancreatic cancer.
This retrospective comparative cohort study evaluated efficacy using clinical outcomes among patients with unresectable pancreatic cancer.
Findings suggest that multi-hole stents may offer a more effective treatment alternative for bile duct obstruction.

Asada et al. (2025) studied this question.
