Study finds bariatric surgery known as sleeve gastrectomy increases the risk of Barrett’s Esophagus, the precursor to Esophageal Adenocarcinoma – the most prevalent form of Esophageal Cancer in the western world.

Compared with another type of gastric bypass known as Roux-en-Y, sleeve gastrectomy poses a significantly higher risk for Barrett’s Esophagus one year after the procedure, and the relative risk continues to climb with longer periods of follow-up, according to a large study based on propensity matching.

No current guidelines make a firm recommendation for endoscopic surveillance of esophagitis and Barrett’s Esophagus after bariatric surgery, but these data suggest that monitoring “may be warranted at least in high-risk patients after sleeve gastrectomy,” reported lead investigator Yousaf Hadi, MD, a fellow in the gastroenterology program at the West Virginia University School of Medicine, in Morgantown.
