Effect of biliary and alimentary limbs lengths of the Roux-en-Y gastric bypass in the control of type 2 diabetes mellitus in patients with Body Mass Index (BMI) 50 kg/m2
Background: Patients With Body Mass Index (BMI) > or = 50kg/m2 may achieve adequate weight loss with long limb RYGB. These patients, however, might need longer intestinal limbs to control co-morbidities such as type 2 diabetes. Methods: A prospective study of 100 super-obese patients who were divided in 2 similar groups regarding sex, age, and number of co-morbidities. All were submitted to laparoscopic RYGB. In group 1, length of biliary limb was 50 cm and length of Roux limb was 150 cm. In group 2, length of biliary limb was 100 cm and of Roux limb was 250 cm. Results: Follow-up was 48 months. Diabetes was controlled in 58% of group 1 patients and in 93% of group 2 patients (p<0.05). Excess weight loss was faster in group 2, but was similar in both groups at 48 months, with no statistical difference. Conclusions: Super-obese patients with longer biliary and Roux limbs achieved greater type 2 diabetes control.
