Abstract

Background

The 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.

Methods

From 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.

Results

In 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.

Conclusion

A linear relationship exists between Roux limb length and 1-year weight loss.

胃旁路术中Roux肢体长度变化与体重减轻的关系

背景胃旁路手术的最佳Roux肢长度尚不清楚。因此，研究Roux肢体长度对Roux-en- y胃旁路手术后体重减轻和营养缺乏的影响。方法自2000年9月至2004年2月，在威廉·博蒙特陆军医疗中心进行了165例Roux-en-Y胃旁路手术。对97例患者进行了为期一年的随访。Roux四肢根据患者的身体质量指数(BMI)从100厘米到150厘米不等。比较Roux肢体长度1年内绝对体重、BMI和营养水平的变化。结果97例患者手术时平均年龄44岁(范围20 ~ 63岁)。术前平均BMI为46.7±6.6 kg/m2，随访1年平均BMI为30.9±5.8 kg/m2。1年平均绝对减重43.7±12.8 kg。Roux肢体长度与BMI和绝对体重下降之间存在统计学上显著的线性关系。Roux肢长与营养水平变化无相关性。结论Roux肢体长度与1年减重呈线性关系。
