The failure pattern for the magnetic sphincter augmentation device: a single-institution case series with literature review.

ABSTRACT:

Background

Magnetic sphincter augmentation (MSA) is an effective surgical treatment for GERD. Removal rates are reported around 4-6%, with dysphagia being the most common indication for removal. This rate has increased over time, and the pattern of device failure has not been well established. This study characterizes a consistent pattern of MSA slippage or migration and contextualizes this within the existing literature on MSA failure.

Methods

This is a single-institution retrospective review of patients who underwent MSA placement and device removal between 2014 and 2024. Radiographic and endoscopic images and operative reports were reviewed for the presence of pre-operative and post-operative hiatal hernia or device malposition. We also conducted a comprehensive review of
