Physiological Archetypes of de novo Gastroesophageal Reflux Disease After Laparoscopic Sleeve Gastrectomy

Abstract

Laparoscopic Sleeve Gastrectomy (LSG) is the most common bariatric surgery in the world. While clinically effective, recent studies have shown increasingly higher rates of gastroesophageal reflux disease (GERD) and esophageal motility disorders. We reviewed all the literature and unraveled the underlying mechanism of post-LSG GERD. Finally, we propose a new classification to help us understand the disease and guide work-up, treatment, and future refinements in the surgical technique.
