Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The investigators propose a randomized controlled trial comparing BP and roux limb lengths measuring 30 and 15% respectively of patient's total small bowel length versus current standard practice using fixed lengths. The findings would provide further insight into feasibility of standardizing RYGB limb lengths and optimizing resultant weight loss and metabolic effects. The investigators hypothesize RYGB with ratio-adjusted limb lengths (aRYGB) will result in higher total weight loss and resolution of metabolic syndrome comorbidities, including diabetes, hyperlipidemia, and hypertension compared to standard fixed-length RYGB (sRYGB). The study will also utilize the Short Form Rand 36-Item Health Survey (SF36) to determine differences in postoperative quality of life metrics.
