Core Tip

Core Tip: One-anastomosis gastric bypass and sleeve gastrectomy are the most commonly performed bariatric surgeries; both are safe and effective for weight reduction and diabetes remission. However, the choice between the two operations is to be determined. In this meta-analysis, we compared the two operations in terms of the complication rate, mortality, operative time/minutes, hospital stay/days, gastroesophageal reflux, nutritional deficiencies, and quality of life. This study gave a broad insight to inform the scientific community and help the surgeon to choose the best intervention for patients with obesity and diabetes.
