Matar R, Maselli D, Vargas E, et al. - In a large cohort with long-term follow-up, researchers studied the prevalence and potential physiologic underpinnings of erosive esophagitis (EE) after bariatric surgery. The study sample consisted of 517 patients who had an esophagogastroduodenoscopy after sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB). Using high-resolution manometry, a matched case-control sub-study was carried out to compare physiologic contributors of gastroesophageal reflux disease (GERD) after SG with a preoperative cohort. According to this retrospective analysis, EE is more common after SG vs RYGB in a prebariatric surgery cohort with GERD. Findings suggested an association of SG with significant esophageal physiologic changes conducive to GERD and its clinical consequences.
