Background: The gastric bypass surgery is one of the most used worldwide for the treatment of obesity and there is no consensus on the ideal size of intestinal loops in gastric bypass of bariatric surgeries. This study assessed the metabolic outcome of patients submitted to gastric bypass with alimentary and biliopancreatic loops of different sizes. Materials and Methods: We conducted a retrospective cohort study in diabetic obese patients (BMI ≥35 kg/m2) with metabolic syndrome submitted to gastric bypass. The patients were divided into 3 groups according to the size of the intestinal loop: group 1, biliopancreatic loop of 50 cm and alimentary loop of 100 cm; group 2, biliopancreatic loop of 50 cm and alimentary loop of 150 cm; and group 3, biliopancreatic loop of 100 cm and alimentary loop of 150 cm. The effect of gastric bypass with different sizes of intestinal loops in relation to the parameters that define metabolic syndrome according to IDF was determined. The postoperative periods evaluated were: 3, 6, 12 and 24 months Results: Sixty-three patients were evaluated, and they had a mean age of 44.7±9.4 years; 62 (98.4%) were hypertensive and 51 (82.2%) dyslipidemic. The 3 groups studied were homogeneous in relation to the variables studied. In 24 months, there was a remission of systemic arterial hypertension in 65% of patients in group 1, 62.5% in group 2 and 68.4% in group 3. Remission of DM2 occurred in 85% of patients in group 1, 83% in group 2 and 84% in group 3. There was no statistical difference in %LEW between the groups, and waist measurements decreased in a homogeneous way in all groups. The size of loops also had no influence on the improvement in dyslipidemia. Conclusion: Variation in size of intestinal loops does not appear to influence improvement in metabolic syndrome in this group of patients.
