BackgroundThe optimal Roux limb length for gastric bypass is unknown. Therefore, the effect of Roux limb length on weight loss and nutritional deficiency after a Roux-en-Y gastric bypass procedure was studied.MethodsFrom September 2000 to February 2004, 165 Roux-en-Y gastric bypass surgeries were performed at William Beaumont Army Medical Center. One-year follow-ups were completed on 97 patients. Roux limbs varied from 100 cm to 150 cm, based on the patient’s body mass index (BMI). Roux limb lengths were compared with 1-year changes in absolute weight, BMI, and nutritional levels.ResultsIn the 97 patients, average age at the time of surgery was 44 years (range, 20-63). Average BMI was 46.7 ± 6.6 kg/m2 before surgery and 30.9 ± 5.8 kg/m2 at 1-year follow-up. Average absolute weight loss at 1 year was 43.7 ± 12.8 kg. A statistically significant linear relationship existed between Roux limb length and reductions in BMI and absolute weight. No relationship existed between Roux limb length and changes in nutrient levels.ConclusionA linear relationship exists between Roux limb length and 1-year weight loss.
