Barrett`s Esophagus in Bariatric Surgery: Regression or Progression?

Introduction: Morbid obesity is well known as a risk factor for gastroesophageal reflux disease (GERD) and its related disorders such as Barrett’s esophagus (BE). This study aimed to evaluate the development of BE in patients who underwent bariatric surgery. Materials and Methods: Using a single-center prospectively established database of obese patients who underwent bariatric surgery from 01/2012 to 12/2019, we retrospectively compared the preoperative endoscopic findings of BE to those after 1–2 years and 3–5 years following bariatric surgery. The change of BE was detected endoscopically according to Prague classification and histologically according to the British guidelines of detecting columnar epithelium on the distal esophagus. Results: Among 914 obese patients who underwent bariatric surgery and received a preoperative esophagogastroduodenoscopy (EGD), we found 119 patients (13%) with BE. A follow-up EGD was performed in 74 of the BE patients (62.2%). A total of 37 (50%) patients underwent a follow-up EGD after 1–2 years and 45 (60.8%) patients underwent it after 3–5 years. Among many clinical parameters, the surgical procedure was the only significant factor for the change of BE after bariatric surgery (p < 0.05). A regression of BE was found in 19 patients (n = 54, 35%) after laparoscopic Roux-en-Y- gastric bypass (LRYGB). Furthermore, a progression of BE was detected in six patients (n = 20, 30%) after laparoscopic sleeve gastrectomy (LSG). Conclusion: RYGB should be considered in obese patients with BE. Detecting BE prior to bariatric surgery may have an impact on decision-making regarding the suitable surgical bariatric procedure. Graphical Abstract: [Figure not available: see fulltext.]
