Comparison of fully covered versus uncovered self-expandable metallic stents in treating inoperable malignant distal biliary obstruction: a retrospective study.

ABSTRACT:

Background

The optimal choice between fully covered self-expandable metallic stents (FCSEMSs) and uncovered self-expandable metallic stent (USEMS) for managing inoperable malignant distal biliary obstruction (MDBO) remains debatable. This study aims to compare the efficacy of CSEMS and USEMS in patients with MDBO.

Method

A retrospective analysis was conducted with inoperable MDBO between January 2017 to December 2021 who underwent either USEMS or FCSEMS implantations via endoscopic retrograde cholangiopancreatography (ERCP). Primary outcomes were overall survival and stent patency. Secondary outcomes were stent occlusion rates and postoperative complications.

Results

This study included 310 patients (235 patients received FCSEMS implantations and 75 received USEMS imp
