- Abstract
- Purpose Resectional Roux-en-Y gastric bypass (RRYGB) is considered an alternative bariatric surgery in countries with a high incidence of stomach cancer because there is no excluded stomach after RRYGB. This study aimed to evaluate the efficacy and safety of RRYGB.Materials and Methods This study included patients who underwent RRYGB and sleeve gastrectomy (SG) between 2011 and 2021. Surgical complications and metabolic and nutritional profiles were compared between the patients preoperatively and at 1, 6, and 12 months after surgery.Results Twenty and seventy-six patients underwent RRYGB and SG, respectively; 7 in the SG group were lost to follow-up within 1 year. Surgical complications and baseline characteristics were comparable between two groups, except for diabetes (90.0% vs. 44.7%, p < 0.001). The decrease of HbA1c levels and incidence of reflux esophagitis were lower in the RRYGB group compared to that of SG at 1-year postoperative (-3.0% vs. -1.8%, p = 0.014; 0% vs. 26.7%, p = 0.027). The percentage of total weight loss at 1- year postoperative and incidence of dumping syndrome were comparable between the two groups. The RRYGB group had significantly lower total cholesterol level (161.9 mg/dl vs. 196.4 mg/dl, p < 0.001), but higher incidence of vitamin B12 deficiency (30.0% vs. 3.6%, p = 0.003) at 1 year postoperative compared to those of the SG group.Conclusions The RRYGB group had better postoperative outcomes for diabetes and dyslipidemia without increasing surgical complications compared to that of the SG group. Thus, RRYGB can be considered a safe and effective alternative in areas where gastric cancer is prevalent.
