Abstract

Introduction

Magnetic sphincter augmentation (MSA) is a safe and effective treatment for patients with gastroesophageal reflux disease (GERD). MSA was initially indicated for patients with GERD and concomitant hiatal hernias < 3 cm. However, excellent short- and intermediate-term outcomes following MSA and hiatal hernia repair in patients with hiatal hernias ≥ 3 cm have been reported. The purpose of this study is to assess long-term outcomes for this patient population.

Methods and procedures

A retrospective review was performed of patients with GERD and hiatal hernias ≥ 3 cm who underwent MSA and hiatal hernia repair. Patients were treated at two tertiary medical centers between May 2009 and December 2016. Follow up included annual video esophagram, upper endoscopy, or both. Outcomes included pre- and post-operative GERD health-related quality of life (GERD-HRQL) scores, length and regression of Barrett’s esophagus, resolution of esophagitis, need for endoscopic dilations or implant removal, and clinically significant hiatal hernia recurrence (> 2 cm) on videoesophagram or endoscopy.

Results

Seventy-nine patients (53% female) with a median age of 65.56 (58.42–69.80) years were included. Median follow up was 2.98 (interquartile range 1.90–3.32) years. Median DeMeester scores decreased from 42.45 (29.12–60.73) to 9.10 (3.05–24.30) (p < 0.001). Severity of esophagitis (e.g. LA class C to class B) significantly improved (p < 0.01). Forty percent of patients with Barrett's esophagus experienced regression (p < 0.01). Median GERD-HRQL scores improved from 21 to 2. Five (6.3%) hiatal hernia recurrences occurred, and 1 required re-operation. Age, body mass index, size of the initial hiatal hernia, and sex had no significant effect on whether a patient developed a recurrence.

Conclusions

Magnetic sphincter augmentation in conjunction with large hiatal hernia repairs for patients with GERD achieves excellent long-term radiographic and clinical results, and a low overall need for reoperation, without the need for mesh.
