Magnetic Sphincter Augmentation for Hiatus Hernia and De Novo Gerd after Sleeve Gastrectomy

Abstract

Laparoscopic sleeve gastrectomy (LSG) has become the most popular bariatric surgical procedure owing to its safety, reproducibility and effectiveness. However, gastroesophageal reflux disease (GERD) with or without hiatal hernia is diagnosed at an alarming rate after LSG. Revisional surgery and conversion to Roux-en-Y gastric bypass (RYGB) does not guarantee total reflux control and is associated with morbidity. Magnetic sphincter augmentation (MSA) combined with crural repair is an alternative therapeutic option as a concurrent or remedial procedure in LSG, but current clinical evidence is still limited.
