Introduction: One anastomosis gastric bypass (OAGB) and Roux-en-Y gastric bypass (RYGB) are successful surgical treatment options for morbid obesity. In this study, we aimed to share our results by comparing these two bypass techniques in a retrospective analysis. Materials and Methods: A retrospective study was conducted at a single center at Samsun Training and Research Hospital. The outcomes of two groups, laparoscopic OAGB and laparoscopic RYGB, were compared. Patients with a BMI over 40 kg/[m.sup.2] and patients with a BMI over 35 kg/[m.sup.2] with obesity-related comorbidities were included. Patient demographics, obesity-related comorbidities, medications, postoperative outcomes, percentage excess weight loss (%EWL), percentage total weight loss (%TWL), and postoperative BMI were recorded retrospectively. Results: A total of 64 patients were retrospectively analyzed. Fifty-one of the patients were female, and thirteen were male. There were 21 patients in the OAGB group and 43 patients in the RYGB group. The mean follow-up period was 42.86[+ or -]3.54 months in the OAGB group and 52.21[+ or -]11.58 months in the RYGB group (p0.05). The mean %EWL was 83.02[+ or -]18.95 and 76.08[+ or -]22.84, respectively (p>0.05). The mean BMI was 29.62[+ or -]5.42 kg/[m.sup.2] in the OAGB group and 30.14[+ or -]5.05 kg/[m.sup.2] in the RYGB group (p>0.05). There was no significant difference in the improvement of obesity-related comorbidities. However, de novo reflux was significantly higher in OAGB patients. Conclusion: OAGB and RYGB are both effective procedures for treating morbid obesity. Both procedures provide similar improvements in obesity-related diseases, although de novo reflux appears to be more common in OAGB patients.
