Roux-en-Y gastric bypass (RYGB) that is performed with at least a 150-cm Roux limb results in significantly greater weight loss than shorter (<100-cm) Roux limb procedures in superobese patients(BMI >50 kg/m2). Conversely, longer Roux limb procedures do not provide greater weight loss in less obese (BMI <50 kg/m2)patients. Modest elongation of the Roux limb-in the range of 150 cm to 200 cm-does not result in more frequent nutritional sequelae compared with shorter Roux limb procedures. This article discusses the current status of long limb Roux-en-Y gastric bypass in the context of weight loss, metabolic sequelae and CPT coding.
对于超级肥胖患者（BMI>50kg/m²），进行至少150厘米 Roux 袢的 Roux-en-Y 胃旁路术（RYGB）导致的体重减轻明显大于 Roux 袢较短（<100厘米）的手术。相反，在肥胖程度较低（BMI<50kg/m²）的患者中，较长 Roux 袢手术并不会带来更多的体重减轻。与 Roux 袢较短的手术相比，将 Roux 袢适度延长至150厘米至200厘米范围内，并不会导致更频繁的营养后遗症。本文在体重减轻、代谢后遗症和CPT编码的背景下讨论了长袢 Roux-en-Y 胃旁路术的现状。
