Abstract

Bariatric surgery is the best therapeutic approach to patients with morbid obesity, but there is mounting evidence that it is associated with esophageal dysfunctions, including gastroesophageal reflux disease (GERD) and motor disorders. In the present review, we summarize the existing information on the complex link between bariatric surgery and esophageal disorders. Although high-quality studies on these effects are lacking, because of evident methodological flaws and retrospective nature, the review of published investigations show that pure restrictive procedures, such as laparoscopic adjustable gastric banding (LAPG) and laparoscopic sleeve gastrectomy (LSG), are associated with de novo development or worsening of GERD. Moreover, LAGB is the procedure with the greatest frequency of esophageal motor disorders, including impairment of LES relaxation and ineffective esophageal peristalsis associated with esophageal dilation. LSG seems to be less associated with esophageal dysmotility, although evidence derived from studies with objective measurements of esophageal dysfunction is limited. Finally, RYGB seems to be the best procedure for improvement of GERD symptoms and preservation of esophageal function. Overall, the restricti...Continue Reading
