Standardized approach to removal of lumen apposing metal stents following endoscopic necrosectomy: one size does not fit all.

ABSTRACT:

Background

Walled-off necrosis (WON) is a sequela of acute necrotizing pancreatitis preferentially managed with lumen apposing metal stents (LAMS). Adverse events including buried stent syndrome and bleeding have been associated with a longer duration of LAMS placement.

Objectives

We attempt to examine our outcomes of a standardized approach to LAMS dwell time and hypothesize that LAMS removal based on imaging characteristics and patient symptoms improves outcomes.

Design

From November 2015 to May 2022, a prospectively maintained database on patients with symptomatic WON undergoing endoscopic drainage with LAMS was retrospectively reviewed and analyzed.

Methods

Patient characteristics, procedure details, and outcomes were recorded. Imaging was performed at 1, 3
