Impact of Gastric Bypass on Erosive Esophagitis and Barret's Esophagus.

Background: The association between gastroesophageal reflux disease (GERD) and obesity is clearly defined. The incidence of erosive esophagitis (EE) and Barrett's esophagus (BE) are as high as 26 and 6%, respectively. Gastric bypass (GBP) is considered the gold standard for obese patients with GERD.

Esophagitis evolution after sleeve gastrectomy or gastric bypass in consecutive cases.

Background: Erosive esophagitis (EE) is related to esophageal mucosal damage caused by GERD and is implicated in the development of Barret´s esophagus and adenocarcinoma, which incidence is rising in association with obesity. It is known that the correlation between symptoms and endoscopic findings is relatively poor, with a predictive value of only 40%. The objective of this study is to report the incidence of EE 1 year after sleeve gastrectomy (SG) and gastric bypass (GBP) in consecutive patients in order to obtain an objective parameter of the impact of the two most popular bariatric procedures on esophageal mucosa.
