Bariatric surgery has been established as the only successful treatment option for morbid obesity and its related comorbidities. The one-anastomosis gastric bypass (OAGB) has currently evolved as a new surgical option for the treatment of obesity that has gained rapid popularity worldwide. Nevertheless, several concerns have been raised concerning its related complications and the need for revision. Aim of the study: This work aimed to compare routine OAGB and OAGB with added ‎enteroenterostomy in the patients’ short-term outcomes including the incidence of gatroesophageal reflux disease (GERD). Patients and methods: This is a randomized controlled study that was conducted on consecutive patients scheduled for OAGB. Patients were randomly allocated to one of two groups; group 1 included patients who underwent LOAGB with added Braun enteroenterostomy, and group 2 included patients who underwent the standard LOAGB. Results: Eighty patients were in the study population; 41 were in group 1, and 39 were in group 2. At 6-months postoperatively, both groups showed significant weight loss (p<0.001 ‎for both). A statistically significant higher %TWL was shown in group 1 (29.68 ± 4.45 ‎vs. 27.86 ± 0.79, p=0.012).‎ Less incidence of gastroesophageal inflammation and bile reflux was shown in the group with added Braun anastomosis. However, with no statistical significance. The scores of the GSFQ ranged from 3 to 25, with statistically significantly higher median values in group 2 (11 vs. 8, p=0.037). ‎Conclusion: Adding Braun anastomoses to LOAGB resulted in less postoperative GERD and a better patient outcome. Further multi-center studies on large samples with long-term follow-up is will help in adopting standardization of the initial adding Braun anastomosis to LOAGB.
