VARASCHIM, Michelle et al. Changes in clinical and laboratory parameters in obese patients with type 2 diabetes mellitus submitted to Roux-en-y gastrojejunal bypass without ring. Rev. Col. Bras. Cir. [online]. 2012, vol.39, n.3, pp. 178-182. ISSN 0100-6991. http://dx.doi.org/10.1590/S0100-69912012000300003.
OBJECTIVES: 1) To assess the changes in body weight and body mass index in grade 2 and 3 obese patients with type 2 diabetes mellitus, pre and postoperatively; 2) to assess the changes in pre and postoperative fasting blood glucose, postprandial glucose, glycated hemoglobin and insulin. METHODS: A prospective study was undertaken with 40 selected patients with grade 2 and 3 obesity and type 2 diabetes mellitus, all with indication for surgical treatment of obesity. All patients underwent Roux-en-Y gastric bypass without ring. The clinical parameters weight and body mass index were analyzed, as well as the laboratory parameters fasting blood glucose, postprandial glucose, glycated hemoglobin, and insulin. The analyses were carried out in the preoperative period and at 60 days postoperatively. Statistical analysis was conducted with Student's t and the Kolmogorov-Smirnov tests. RESULTS: Mean preoperative weight was 107.3 kg, declining to 89.5 kg postoperatively. Mean initial body mass index was 39.5 kg/m2, and 32.9 kg/m2 at 60 postoperative days. Preoperative fasting blood glucose was 132 mg/dL, which was reduced to 40.4 mg/dL, on average, postoperatively. Postprandial blood glucose was 172 mg/dL in the preoperative period and 111.6 mg/dL in the postoperative measurement. Initial glycated hemoglobin was 7%, declining to 5.7% postoperatively. Preoperative and postoperative insulin levels were 29.6 µIU/mL and 13.9 µIU/mL, respectively. The level of significance was p<0.001 for all variables. CONCLUSION: There was a statistically significant reduction in body weight and body mass index between the pre and postoperative periods, as well as in fasting blood glucose, postprandial glucose, glycated hemoglobin.
