Background The prevalence of gastroesophageal reflux disease (GERD) in the morbidly obese population is as high as 45%. The objective of this study was to compare the efficacy of various bariatric procedures in the improvement of GERD. Methods The Bariatric Outcomes Longitudinal Database is a prospective database of patients who undergo bariatric surgery by a participant in the American Society of Metabolic and Bariatric Surgery Center of Excellence program. GERD is graded on a 6-point scale, from 0 (no history of GERD) to 5 (prior surgery for GERD). Patients with GERD severe enough to require medications (grades 2, 3, and 4) from June 2007 to December 2009 are identified; the resolution of GERD is noted based on 6-month follow-up. Results Of a total of 116,136 patients, 36,938 patients had evidence of GERD preoperatively. After excluding patients undergoing concomitant hiatal hernia repair or fundoplication, there were 22,870 patients with 6-month follow-up. Mean age was 47.6±11.1 years, with an 82% female population. Mean BMI was 46.3±8.0 kg/m2. Mean preoperative GERD score for patients with Roux-en-Y gastric bypass (RYGB) was 2.80±.56, and mean postoperative score was 1.33±1.41 (P<.0001). Similarly, adjustable gastric banding (AGB, 2.77±.57 to 1.63±1.37, P<.0001) and sleeve gastrectomy (SG, 2.82±.57 to 1.85±1.40, P<.0001) had significant improvement in GERD score. GERD score improvement was best in RYGB patients (56.5%; 7955 of 14,078) followed by AGB (46%; 3773 of 8207) and SG patients (41%; 240 of 585). Conclusion All common bariatric procedures improve GERD. Roux-en-Y gastric bypass is superior to adjustable gastric banding and sleeve gastrectomy in improving GERD. Also, the greater the loss in excess weight, the greater the improvement in GERD score.
