Effect of Limb Length Ratio on Roux-en-Y Gastric Bypass Outcomes (CLIMB II Study) (NCT06293703)

๐ŸŸข Recruiting Observational / Diagnostic ๐Ÿฉบ Clinical Procedure Protocol Sponsor: Salvador Navarrete

๐Ÿฉบ Plain-English Summary (8th-Grade Level)

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.
