RESUMEN
BACKGROUND: The incidence of obesity and its most feared comorbidity, diabetes mellitus type 2, is increasing and there would not seem to be any medical treatment to help control these pandemics. However, there is a bariatric surgery technique, the Roux-en-Y Gastric Bypass (RYGB), which is safe and not only helps control excess weight, but produces encouraging results in the control and remission of diabetes. METHODS: We present 15 selected patients with a BMI between 30 and 35 kg/mt² and diabetes type 2 who underwent a laparoscopic RYGB with of one-year follow-up. RESULTS: A total of 14 women and one man were operated with the following average values: age: 37 years, weight: 88.3 kg, BMI: 32.8 kg/mt², blood glucose: 120 ± 38.8 mg%, HbA1c: 7.6 ± 0.73. Forty percent (40%) suffered from high blood pressure and 33.3% were dyslipidemic. Average surgical time was 75 minutes, hospital length of stay was two days, and there was a low rate of complications and no mortality. Diabetes remission was achieved in 93% of cases with significant drops in blood glucose and HbA1c (p ≤ 0.05 and p ≤ 0.001 respectively), dyslipidemia was 100% controlled and hypertension was 83.3% controlled. CONCLUSIONS: RYGB in selected patients with obesity type 1 and diabetes mellitus type 2 is a safe and effective technique for metabolic control and obesity control.
