Abstract

Purpose: Sleeve gastrectomy (SG) is the most commonly performed bariatric surgical procedure worldwide. However, the impact of SG on Barrett's esophagus (BE) remains unknown. The main objective was to determine the rate of BE 5 years after SG.

Materials and methods: Patients, operated in 2012 by SG in one center, who preoperatively and postoperatively (5 years) underwent upper gastrointestinal endoscopy (UGIE), 24-h pH monitoring, and esophageal manometry, were included.

Results: A total of 59 (81.4% of females) patients were included. Preoperative mean age and body mass index were 45.2 ± 11.7 years and 45.2 ± 8.1 kg/m2 respectively. Preoperative 24-h pH monitoring reported gastroesophageal reflux disease (GERD) in 18 (30.5%) patients. The mean total body weight loss at 5 years was 16.1 ± 11.2%. No significant difference was observed between preoperative and postoperative de Meester's score (20.2 ± 27.1 and 21.0 ± 21.5 respectively (p = 0.91)) nor between preoperative and postoperative number of acid reflux episodes per 24 h (65.1 ± < 40.0 and 50.3 ± 40.3 (p = 0.21)). The UGIE revealed 5 patients (8.5%) with endoscopically suspected esophageal metaplasia, without confirmed metaplasia on histologic examination. GERD was diagnosed in 32 patients (54.2%), de novo GERD in 16 (27.1%) patients and esophagitis in 16 (27.1%) patients. At 5 years, 25 patients (42.4%) reported a lack of regular medical follow-up.

Conclusions: This study highlights the incidence of postoperative GERD and endoscopic lesions following SG. Even though SG is not contraindicated in case of reflux, GERD patients who undergo SG may be supervised by a close endoscopic surveillance.
