  • Title: Effects of bariatric surgery on gastroesophageal reflux.
    Author: Tutuian R.
    Journal: Curr Opin Gastroenterol; 2014 Jul; 30(4):434-8. PubMed ID: 24867157.
    Abstract:
    PURPOSE OF REVIEW: Obesity and gastroesophageal reflux disease (GERD) are two prevalent conditions with important impact on health resource utilization around the world. Obesity is a known risk factor in the pathogenesis of GERD. When conservative measures fail, bariatric surgery remains the only option to lose weight and correct obesity-related comorbidities. The influence of bariatric surgery on GERD depends on which bariatric intervention is used. RECENT FINDINGS: Recent studies indicate that laparoscopic gastric banding and laparoscopic sleeve gastrectomy have little influence on preexisting GERD symptoms and findings, but some patients may develop GERD after laparoscopic sleeve gastrectomy. A number of studies have documented that laparoscopic Roux-en-Y gastric bypass improves GERD symptoms and findings, making it the preferred procedure for morbid obese patients with concomitant GERD. SUMMARY: Current findings provide good arguments for searching for and treating GERD in patients scheduled to undergo bariatric surgery. The presence of GERD might represent a relative contraindication for sleeve gastrectomy or gastric banding or both. Gastric bypass might be the procedure of choice in morbid obese patients with GERD symptoms or findings or both.
