However, there are no current comparative studies on the safety and efficacy of these two surgical procedures.Patients and Methods: Preoperative baseline data of patients who had undergone OAGB and SADJB-SG surgeries from June 2019 to June 2021 were retrospectively analyzed at our bariatric facility. Postoperative data, including weight changes, improvement in type 2 diabetes (T2DM), and complication rates were collected over 2 years. This was followed by a comprehensive evaluation of the safety and efficacy of the two surgical procedures.Results: A total of 63 patients completed the follow-up in this study. At the 24-month follow-up, excess weight loss percentage (EWL%) for the OAGB and SADJB-SG was 73.970± 5.005 and 75.652± 7.953, respectively (P-value = 0.310); total weight loss percentage (TWL%) was 24.006± 8.231 and 23.171± 6.600, respectively (P-value = 0.665). The diabetes remission rates for the two groups were 71.429% and 69.048%, respectively (P-value = 0.846). The cost for OAGB was 55088.208± 1508.220 yuan, which was significantly lower than the 57538.195± 1374.994 yuan for SADJB-SG (P-value< 0.001).Conclusion: The two surgical procedures are reliable in terms of safety and efficacy, and each has distinct advantages. While OAGB has reduced operational expenses, SADJB-SG offers a broader range of applicability.Keywords: one anastomosis gastric bypass, single anastomosis duodeno-jejunal bypass with sleeve gastrectomy, safety, efficacy
