Abstract: Laparoscopic sleeve gastrectomy is the most popularly performed bariatric surgery procedure. However, the incidence of postoperative gastroesophageal reflux disease (GERD) is increased in obesity patients. Obesity patients undergoing bariatric surgery are often accompanied with GERD. The de novo GERD is also common after sleeve gastrectomy. Therefore, GERD is the most common and important long-term complication following sleeve gastrectomy. The author reviews literature and combines own clinical experience to elaborate on the selection of surgical methods for obesity patients with GERD, the prevention of GERD in sleeve gastrectomy, and the management of postoperative GERD.
