The effect of laparoscopic sleeve gastrectomy on the antireflux mechanism: can it be minimized?

Background Laparoscopic sleeve gastrectomy (LSG) is a promising procedure for the treatment of morbid obesity. The stomach is usually transected near the angle of His; hence, the lower esophageal sphincter (LES) may be affected with consequences on postoperative gastroesophageal reflux disease (GERD). The purpose of this study was to examine the effect of LSG on the LES and postoperative GERD.
