"The analysis confirmed that the selected bariatric surgeries (i.e., sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB)) can achieve improved health outcomes while saving costs in obese patients with T2DM (i.e., “dominant” treatment options) compared to conventional diabetes treatment. This “dominance” was confirmed in all three BMI categories. In addition, these bariatric surgeries extended the time to the first appearance of most diabetic complications. The robustness of the analysis was supported by the results of the scenario analyses that confirmed the results of the base-case analysis: SG and RYGB proved to be cost saving and QALY improving treatments even when assumptions were made that worsened the effectiveness or increased the costs of the surgeries."
