MedicalResearch.com: What is the background for this study? What are the main findings?
Response: For many years, bariatric surgery is performed to treat class II and III obesity with diabetes remission in 80-90% of cases, related to weight loss and change in the secretion of intestinal factors that control blood glucose, like GLP-1 and GIP.
In 2010, the International Diabetes Federation (IDF), proposed that diabetic patients with BMI between 30-35kg/m2 could be eligible, for bariatric surgery, in the case of no glycemic control with drug treatment. In this context, once glycemic control after bariatric surgery, was not related only to weight loss and also due to intestinal factors with physiological actions, the protocol was proposed.
The objectives were to compare the clinical and surgical treatment in diabetics patients with class I obesity; and to compare the efficacy and security between two different surgical techniques.
This study was developed and conducted by a research team from Sirio-Libanês Hospital in partnership with Ministry of Health through its philanthropic program PROADI. It is a clinical trial, with 42 class I obese diabetic type 2 patients with inadequate glycemic control that were randomized to tree arms: clinical treatment, gastric bypass surgery or sleeve with ileal transposition (sleeve-IT) surgery.
The results showed that the sleeve-IT procedure is more effective for the treatment of diabetes in these patients compared with treatment with medication and with bypass surgery, currently considered the first choice of treatment. Among patients who underwent sleeve-IT, 100% achieved glycemic control after 1 year (HbA1c<6,5%) compared to 46% for bypass and 8% in the case of medication therapy. In addition, diabetes remission, that was defined as adequate glycemic control without any anti-diabetic medication, occured in 75% of sleeve-IT patients had versus 30% in bypass group.
