Gastric banding (GB) and vertical banded gastroplasty (VBG) may result in unsatisfactory weight loss or intolerable side effects. Such outcomes are potential indications for additional bariatric surgery, and Roux-en-Y gastric bypass is frequently used at such revisions (rRYGB). The present study examined long-term results of rRYGB.
In total, 175 patients who had undergone rRYGB between 1993 and 2003 at 2 university hospitals received a questionnaire regarding their current status. The questionnaire was returned by 131 patients (75% follow-up rate, 66 VBG and 65 GB patients). Blood samples were obtained and medical charts studied. The reason for conversion was mainly unsatisfactory weight loss among the VBG patients and intolerable side effects among GB patients.
The 131 patients (112 women), mean age 41.8 years at rRYGB, were evaluated at mean 11.9 years (range 7-17) after rRYGB. Mean body mass index of those with prior unsatisfactory weight loss was reduced from 40.1 kg/m(2) (range 28.7-52.2) to 32.6 kg/m(2) (range 19.1-50.2) (P<.01). Only 2 patients (2%) underwent additional bariatric surgery after rRYGB. The overall result was satisfactory for 74% of the patients. Only 21% of the patients adhered to the recommendation of lifelong multivitamin supplements while 76% took vitamin B12. Anemia was present in 18%.
rRYGB results in sustained weight loss and satisfied patients when VBG or GB have failed. Subsequent bariatric surgery was rare but micronutrient deficiencies were frequent.
胃束带（GB）和垂直捆绑胃成形术（VBG）可能导致不满意的体重减轻或无法忍受的副作用。这些结果是额外减重手术的潜在指征，并且 Roux-en-Y 胃旁路术经常用于此类修订（rRYGB）。本研究检查了 rRYGB 的长期结果。
共有 175 名患者在 2 家大学医院于 1993 年至 2003 年之间接受了 rRYGB，他们收到了一份关于他们目前状况的问卷。共有 131 名患者（75%的随访率，66 名 VBG 和 65 名 GB 患者）返回了问卷。采集了血样并研究了病历。VBG 患者的主要转换原因是不满意的体重减轻，而 GB 患者的主要转换原因是无法忍受的副作用。
131 名患者（112 名女性），rRYGB 时的平均年龄为 41.8 岁，在 rRYGB 后平均 11.9 年（7-17 年）进行了评估。体重指数不理想的患者体重从 40.1kg/m²（范围 28.7-52.2）降至 32.6kg/m²（范围 19.1-50.2）（P<.01）。仅 2 例患者（2%）在 rRYGB 后再次接受了减重手术。74%的患者对整体结果感到满意。只有 21%的患者坚持终身服用多种维生素补充剂的建议，而 76%的患者服用维生素 B12。18%的患者存在贫血。
当 VBG 或 GB 失败时，rRYGB 可导致持续的体重减轻和满意的患者。随后的减重手术很少见，但微量营养素缺乏很常见。
