Abstract
The prevalence of gastrointestinal reflux disease and reflux-related complications continue to rise, and treatment
options are limited. Medical management alone is often ineffective and chronic use carries inherent risk. Magnetic
sphincter augmentation represents a reasonable and viable treatment option for appropriately selected patients.
Compared to surgical wraps, magnetic sphincter augmentation (MSA) may provide similar rates of patient
satisfaction, anti-acid medication cessation, and decreased esophageal acid exposure. Additionally, MSA may
lower postoperative gas bloat symptoms and better preserve the ability to belch or vomit, versus surgical wraps.
Magnetic sphincter augmentation, however, is still relatively new, and further study is needed to evaluate and
compare outcomes more appropriately to that of surgical wraps.

INTRODUCTION
Gastroesophageal reflux disease (GERD) is highly prevalent and increasing worldwide. Reported rates
approach 30% in North America, 26% in Europe, 33% in the Middle East, and 8% in East Asia . Incidence
