Physiopathological and anatomical consequences post tubular vertical gastrectomy as possible causes of gastro-esophageal reflux disease

Abstract

Tubular vertical gastrectomy (GVT) or sleeve gastrectomy has been validated as an effective bariatric procedure to treat patients with morbid obesity. Anatomical and pathophysiological changes have been described in the esophagogastric junction that may be related to the pathogenesis of gastroesophageal reflux disease. This article shows the results of our own experience and the literature regarding changes in esophageal and gastric function, the acid reflux test, endoscopic and radiological studies in patients undergoing GVT. It is concluded that GVT can present anatomical and physiopathological changes that are associated with the appearance of gastroesophageal reflux disease.
