Abstract
This study aimed to investigate the efficacy of one-anastomosis gastric bypass (OAGB) on gastroesophageal reflux disease (GERD) compared with Roux-en-Y gastric bypass (RYGB) in patients with obesity. Three databases (Medline, Cochrane Central, and Scopus) were searched for relevant articles published until August 12, 2024. A total of nine randomized controlled trials, including 643 patients, were selected. OAGB was statistically significantly associated with a higher risk of GERD than RYGB (OR = 3.14, 95% CI 1.23-8.03, p < 0.05). The odds for de novo GERD after OAGB are almost six times higher than after RYGB (OR = 5.65, 95% CI 1.53-20.82, p < 0.05). RYGB has a lower incidence of de novo GERD cases and is more effective than OAGB in reducing GERD.
期刊介绍：
Obesity Surgery is the official journal of the International Federation for the Surgery of Obesity and metabolic disorders (IFSO). A journal for bariatric/metabolic surgeons, Obesity Surgery provides an international, interdisciplinary forum for communicating the latest research, surgical and laparoscopic techniques, for treatment of massive obesity and metabolic disorders. Topics covered include original research, clinical reports, current status, guidelines, historical notes, invited commentaries, letters to the editor, medicolegal issues, meeting abstracts, modern surgery/technical innovations, new concepts, reviews, scholarly presentations and opinions.
Obesity Surgery benefits surgeons performing obesity/metabolic surgery, general surgeons and surgical residents, endoscopists, anesthetists, support staff, nurses, dietitians, psychiatrists, psychologists, plastic surgeons, internists including endocrinologists and diabetologists, nutritional scientists, and those dealing with eating disorders.
