Common Limb Length Does Not Influence Weight Loss After Standard Laparoscopic Roux-En-Y Gastric Bypass

Materials and Methods
We performed a laparoscopic RYGBP in 90 patients with a mean preoperative body mass index (BMI) of 44.8. ALL and BPLL were respectively fixed at 150 and 75 cm. A systematic intraoperative measurement of CLL was performed.
As expected, we found a great variation of the jejuno-ileal length and also of the CLL. We created three subgroups of patients: one with the entire population, one excluding the super-obese patients (BMI > 50) and the third one excluding the revisions. There was no statistically significant correlation between CLL and excess BMI loss (EBMIL) at 1, 3, 6 and 12 months of follow-up in each group. We also found a linear correlation between the jejuno-ileal length and the height of individuals.
With a fixed 150-cm ALL and a 75-cm BPLL, there is no evidence that the anatomical variations of CLL could influence weight loss after classical RYGBP.
