Risk factors of early dysfunction after switching from plastic to metal stents in malignant extrahepatic biliary obstruction.

ABSTRACT:

Background

Patients diagnosed with extrahepatic malignant biliary obstruction (MBO) often initially undergo endoscopic retrograde biliary drainage with a plastic stent (PS). Self-expandable metallic stents (SEMSs) have been shown to yield better outcomes than PS. This study aimed to identify predictors of early SEMS dysfunction in MBO patients who initially received PS and subsequently underwent SEMS placement.

Methods

We retrospectively analyzed patients who received their first SEMS insertion following prior PS placement for distal extrahepatic MBO between January 2015 and December 2021. We also analyzed the possible risk factors for early SEMS dysfunction defined as occurring within 90 days.

Results

Fifty-six patients who received their first SEMS for distal extrah
