IBC Oxford Oral Abstract 18 - Evaluation of bariatric surgery outcomes in obesity associated with type 2 diabetes mellitus

Abstract Background Currently, obesity in combination with type 2 diabetes mellitus (T2DM) represents a significant medical and social challenge for healthcare systems. Bariatric surgery has demonstrated high efficacy in weight reduction and achieving T2DM remission; however, the long-term outcomes and the optimal surgical approach remain subjects of debate. Modern studies confirm that bariatric procedures contribute to significant weight loss and improved glycemic control. Most patients experience remission or a substantial reduction in the need for antidiabetic medications. However, the recurrence rate of diabetes and long-term complications require further investigation. Objective To enhance the outcomes of surgical treatment for obesity associated with T2DM by developing and clinically implementing a modified laparoscopic mini-gastric bypass technique. Methods and results A total of 260 patients with obesity and T2DM who underwent surgery between 2020 and 2024 were included in the study. Patients were divided into two groups: Comparison group (n = 110): Patients who underwent conventional surgical treatment. Main group (n = 150): Patients who underwent our modified laparoscopic mini-gastric bypass procedure. We developed a novel method for securing gastro-jejunal anastomosis by additional suturing of the afferent loop of the small intestine to the gastric remnant wall. This technique reduced the risk of anastomotic displacement and associated complications. Furthermore, the proposed method for preventing afferent loop syndrome allowed us to identify its causes, which served as the basis for developing our modified technique (a positive decision on the invention has been obtained, Patent of Uzbekistan). Conclusion The application of the modified technique in patients with obesity and T2DM reduced the incidence of bariatric surgery-related complications from 18.4% to 4.7%.
