Relationship Between Bariatric Surgery and Gastroesophageal Reflux Disease: a Systematic Review and Meta-analysis

AbstractThe purpose of this study was to investigate the relationship between bariatric surgery (laparoscopic sleeve gastrectomy [LSG] and laparoscopic Roux-en-Y gastric bypass [LRYGB]) and gastroesophageal reflux disease (GERD). The number of obese patients with newly onset, worsened, or improved GERD after bariatric surgery in each article were extracted. In the pooled analysis, LSG was associated with a higher risk of GERD than LRYGB (odds ratio [OR] = 5.10, 95% confidence interval [CI] 3.60 –7.23,p< 0.001). Compared with LSG, LRYGB had a better effect on GERD (OR = 0.19, 95% CI 0.12 –0.30,p< 0.001). LRYGB was more effective for treating GERD in obese patients than LSG and the incidence of newly onset GERD after LRYGB was lower.
