Abstract

Introduction

The aim of this study is to compare the outcomes between patients undergoing very-very long limb RYGB (VVLL-RYGB) and proximal RYGB (PRYGB) after adjustable gastric banding (LAGB).

Methods

All patients undergoing conversion from LAGB to RYGB in a bariatric reference center between 2010 and 2016 were analyzed.

Results

Sixty-six patients (80 % female, mean age 44.5 ± 9 years, pre-revisional BMI 40.2 ± 7.4 kg/m2) underwent conversion from LAGB to VVLL-RYGB, and 26 patients (88 % female, mean age 46.9 ± 7.6 years, pre-revisional BMI 37.2 ± 5.3 kg/m2) to PRYGB. ΔBMI 5 years after conversion was 8.2 ± 6.1 kg/m2 in VVLL-RYGB compared to 6.7 ± 5.1 kg/m2 in PRYGB (p = 0.35). There was no significant difference in long-term morbidity. Further revisional procedures after VVLL-RYGB occurred in 10 (15.1 %) and 8 (30.8 %) after PRYGB (p = 0.136).

Conclusion

VVLL-RYGB and PRYGB after LAGB are safe and lead to significant and sustainable additional weight loss without difference in BMI loss between the procedures after 5 years.

胃束带术后复查Roux-en- y胃旁路术，无论Roux肢体长度如何，均可导致持续且显著的额外体重减轻

本研究的目的是比较可调节胃束带（LAGB）后行超长肢RYGB （VVLL-RYGB）和近端RYGB （PRYGB）患者的预后。方法对2010 - 2016年在某体重参考中心接受LAGB向RYGB转化的所有患者进行分析。结果66例患者（女性80%，平均年龄44.5±9岁，修正前BMI 40.2±7.4 kg/m2）从LAGB转换为VVLL-RYGB， 26例患者（女性88%，平均年龄46.9±7.6岁，修正前BMI 37.2±5.3 kg/m2）转换为PRYGB。ΔBMI转换后5年VVLL-RYGB为8.2±6.1 kg/m2，而PRYGB为6.7±5.1 kg/m2 （p = 0.35）。两组长期发病率无显著差异。VVLL-RYGB术后10例（15.1%），PRYGB术后8例（30.8%）进一步复查（p = 0.136）。结论vvll - rygb和PRYGB在LAGB后是安全的，并且在5年后两种方法之间的BMI下降无差异，可导致显著和持续的额外体重减轻。
