Abstract
Laparoscopic sleeve gastrectomy (LSG) is a potentially refluxogenic operation while Laparoscopic Roux-en-Y Gastric Bypass (LRYGB) is regarded as an anti-reflux procedure. The aim of this study is to compare long-term incidence of Barrett's Oesophagus (BO) and gastroesophageal reflux disease (GORD) following LSG and LRYGB. Participants of a double-blinded randomized controlled trial comparing banded LRYGB and LSG for remission of type 2 diabetes were contacted to take part. A gastroscopy was performed. Primary outcome was endoscopic and histologic evidence of BO. Secondary outcomes included reflux and regurgitation scores, presence of oesophagitis, proton-pump inhibitor (PPI) usage, Body Mass Index (BMI), and percentage excess weight loss (%EWL). Forty-eight of 109 patients were enrolled into the study (LSG 26 vs. LRYGB 22). Mean follow-up was 7.5 years for the LSG group, and 7.4 years for the RYGB group (P = 0.22). 8 LSG patients had BO while 3 LRYGB patients had BO (30.8%vs13.6%, P = 0.19). There was no significant difference in the mean reflux (8.1 ± 9.4(0-36) vs. 9.3 ± 8.8(0-34), P = 0.47) and regurgitation scores (7.7 ± 6.9(0-22) vs. 11.5 ± 10.5(0-44), P = 0.23) for LSG versus LRYGB patients or between those with and without BO. PPI usage before and after surgery was 6/26 (23.1%) versus 13/26 (50.0%) and 8/22 (36.4%) versus 12/22 (54.5%) for LSG and LRYGB patients respectively. PPI usage in patients with and without BO was 7/11 versus 18/37. EWL was significantly greater (P = 0.0013) in the LRYGB group (74.8 ± 28.1%) compared to LSG group (49.7 ± 18.7%). Long-term incidence of BO trended towards but was not significantly higher for LSG compared to LRYGB group. We support routine endoscopic surveillance for bariatric patients.
