Comparison of the Usefulness of Covered and Uncovered Laser-cut Metal Stents.

ABSTRACT:

Objectives

This study aimed to evaluate the clinical characteristics of laser-cut self-expandable metal stents (SEMS) and to compare the outcomes between covered and uncovered laser-cut SEMS for malignant distal biliary obstruction (MDBO).

Methods

A multicenter retrospective analysis was conducted across eight Japanese university hospitals, including 124 patients (81 with covered and 43 with uncovered SEMS). Treatment outcomes, recurrent biliary obstruction (RBO), survival, and treatment-related adverse events (tAEs) were compared.

Results

The rates of technical success (100% vs. 100%) and clinical success (94% vs. 98%) were comparable between the two groups. However, the incidence of RBO was significantly higher in the uncovered SEMS group compared to the covered SEM
