Prevalence of Endoscopic Findings Before Bariatric Surgery and Their Influence on the Selection of the Surgical Technique.

Preoperative UGE allows the diagnosis of asymptomatic esophagitis related to gastroesophageal reflux disease and the identification of asymptomatic polyps and ulcers, with the potential ability for malignant transformation. In up to 3.17% of the cases, the endoscopic findings changed the operative strategy. As the complication rate associated with the procedure is low, we recommend the routine performance of preoperative UGE before bariatric surgery.
