Abstract：
Bariatric surgery is being undertaken more frequently in response to rising levels of obesity but is increasingly also requested as a cosmetic choice. Nutritional deficiencies are a recognised consequence of gastrectomy, with potentially severe and permanent neurological sequelae. We present two cases of acute, severe polyneuropathy following sleeve gastrectomy. Severe thiamine deficiency was considered in both cases but with delayed proof and a significant initial differential diagnosis. Neurologists must have a high index of suspicion for the peripheral as well as central presentations of thiamine deficiency to avoid permanent disability. We also call for explicit information resources warning of the risk and signs of thiamine deficiency to be provided routinely to patients after gastrectomy.
摘要：
为了应对肥胖水平的上升，减肥手术越来越频繁，但也越来越多地要求将其作为美容选择。营养缺乏是胃切除术的公认后果，有严重的永久性神经后遗症.我们提出了两个急性病例，袖状胃切除术后的严重多发性神经病。在这两种情况下都考虑了严重的硫胺素缺乏症，但有延迟的证明和显着的初步鉴别诊断。神经科医生必须对硫胺素缺乏症的外周和中枢表现有很高的怀疑指数，以避免永久性残疾。我们还呼吁在胃切除术后常规向患者提供明确的信息资源，警告硫胺素缺乏的风险和体征。
