Long-long limb Roux-en-Y gastric bypass is more efficacious in treatment of type 2 diabetes and lipid disorders in super-obese patients

Abstract Background Super-obese patients can achieve adequate weight loss with long limb Roux-en-Y gastric bypass (RYGB). These patients, however, might need longer intestinal limbs to control co-morbidities such as type 2 diabetes, lipid disorders, hypertension, sleep apnea, and gastroesophageal reflux disorder. Methods A total of 105 patients with a body mass index of ≥50 kg/m 2 were randomly divided into 2 similar groups regarding sex, age, and number of co-morbidities. All underwent laparoscopic Roux-en-Y gastric bypass. In group 1, the length of the biliary limb was 50 cm and the length of the Roux limb was 150 cm. In group 2, the length of the biliary limb was 100 cm and the length of the Roux limb was 250 cm. Results The follow-up for both group was 48 months. Diabetes was controlled in 58% of group 1 and in 93% of group 2 ( P P Conclusion Patients with longer biliary and Roux limbs achieved greater type 2 diabetes control, greater lipid disorder improvement, and showed a trend toward faster excess weight loss.
