Gastroesophageal reflux disease (GERD) is an issue after one anastomosis gastric bypass (OAGB) and modification of OAGB with adding an anti-reflux system may decrease the incidence of postoperative GERD. This study aimed to compare the efficacy of the anti-reflux mechanism to treat preoperative GERD and prevent de novo GERD.
Methods
A prospective randomized clinical trial study was conducted on patients with a body mass index of 40 and more from August 2020 to February 2022. Patients undergoing one anastomosis gastric bypass with and without anti-reflux sutures (groups A and B, respectively). These patients had follow-ups for one year after the surgery. GERD symptoms were assessed in all the patients using the GERD symptom questionnaire.
Results
The mean age was 39.5 ± 9.8 years and 40.7 ± 10.2 years in groups A and B respectively. GERD symptoms remission occurred in 76.5% and 68.4% of patients in groups A and B, respectively. The incidence of de novo GERD symptoms was lower in group A, compared to group B (6.2% and 16.1% in groups A and B respectively), without any statistically significant difference (p-value: 0.239).
Conclusion
GERD symptoms and de novo GERD after OAGB seems to be under-reported after OAGB. This study suggests that applying an anti-reflux suture can decrease de novo GERD symptoms.
