Gastric Bypass With Different Lengths of the Bilipancreatic Limb — BPG-1  

Obesity Clinical Trial

Official title: Randomized Clinical Trial on the Outcome of Gastric Bypass With Biliopancreatic and Alimentary Limbs of 150 Centimeters (cm)/70 cm Versus(vs) 70/150 cm, Measuring the Length of the Common Limb

Status Active, not recruiting

Clinical Trial Summary

Laparoscopic Roux-en-Y Gastric Bypass (LRYGB) has been the most performed bariatric surgical intervention until a few years ago, due to its good results in terms of weight loss and remission of comorbidities such as hypertension, type 2 diabetes mellitus, dyslipidemia and obstructive sleep apnea syndrome. However, more than 25% of patients do not obtain the expected result. There is no uniform technique to perform a LRYGB, but traditionally it was constructed using a long alimentary limb (AL) and a short biliopancreatic limb (BPL). There is no current consensus on the ideal length of the LRYGB limbs. The distal gastric bypass at the expense of a longer biliopancreatic limb (LBPL-GB) could induce more excess of weight loss (EWL%), but with possible protein malnutrition depending on the length of the remaining common limb. The aim of this study is compare a LBPL-GB (BPL 150cm, AL 70cm) with LAL-GB (BPL 70cm, AL 150cm). PRIMARY OUTCOME: to evaluate if there are differences in weight loss. SECONDARY OUTCOME: to assess whether there are differences in both groups in remission of the most common comorbidities and in quality of life. DESIGN: multicenter, prospective, randomized study in blocks (1:1), blinded for the patient and to the surgeon up to the time of intervention, in patients with indication of RYGB for obesity (BMI>35 with associated comorbidity or BMI>40 with or without comorbidity, excluding those of BMI>50). Intervention: LRYGB type 1 (LAL-GB: 150cm ALand 70cm BPL) or type 2 (LBPL-GB: 70cm AL and 150cm BPL). The expected result is that the patients with LBPL-GB present better EWL%, and higher remission of their comorbidities than the comparison group
