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 > or =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 <0.05). Lipid disorders improved in 57% of group 1 and in 70% of group 2 (P <0.05). No statistical difference was found in the control or improvement of hypertension, sleep apnea, or gastroesophageal reflux disorder. The excess weight loss was faster in group 1 but was similar in both groups at 48 months (70% in group 1 and 74% in group 2), with no statistical difference. 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.
