Proximal Roux-en-Y gastric bypass: Addressing the myth of limb length.

ABSTRACT:

Background

Some studies suggest that changes in weight or metabolic outcomes are affected by the lengths of the gastrointestinal limbs in the Roux-en-Y gastric bypass.

Methods

Participants (N = 1,770) underwent primary Roux-en-Y gastric bypass and were followed ≤7 years in the Longitudinal Assessment of Bariatric Surgery-2, a multicenter US cohort study. Alimentary limb and biliopancreatic limb lengths were measured according to research protocol; common channel was measured in a subsample (N = 547). Aimentary limb, biliopancreatic limb, and common channel ratio to total small bowel length were calculated.

Results

Median presurgery body mass index was 46 (25th-75th percentile: 43-51) kg/m². Medians (25th-75th percentiles) for alimentary limb length were 125
