Key result
Longer biliopancreatic limbs are linked to ~5% greater excess weight loss at 36 months.
Why the study?
The study was conducted to evaluate the effect of biliopancreatic limb and alimentary limb length on weight loss outcomes following Roux-en-Y gastric bypass.
Does the length of the biliopancreatic and alimentary limbs affect excess weight loss in morbidly obese patients undergoing Roux-en-Y gastric bypass?
Population
313 morbidly obese patients who underwent primary laparoscopic RYGB
Comparison
Three BPL and AL limb length configurations
Design
Retrospective cohort study
Follow-up
36 months

Should not yet change RYGB limb lengths in practice; leaves open confirmation of benefit in randomized trials.

Does the length of the biliopancreatic and alimentary limbs affect excess weight loss in morbidly obese patients undergoing Roux-en-Y gastric bypass?
Mean Difference: 5.43 (95% CI 1.91–8.95)
p-value: p=0.002
A longer biliopancreatic limb with a shorter alimentary limb in Roux-en-Y gastric bypass is associated with greater excess weight loss at 36 months postoperatively.
Pazouki et al. (2019) conducted a cohort in Morbid obesity (n=313). Longer biliopancreatic limb and shorter alimentary limb vs. Shorter biliopancreatic limb and longer alimentary limb was evaluated on Percentage excess weight loss (%EWL) (MD 5.43%, 95% CI 1.91-8.95, p=0.002). Patients with a longer biliopancreatic limb and shorter alimentary limb had a 5.43% (95% CI 1.91-8.95; p=0.002) higher mean excess weight loss at 36 months compared to those with a shorter biliopancreatic limb.
