Abstract：
Outcomes after adjustable gastric banding (AGB) were unsatisfactory and many devices need to be removed for dysphagia. Vitamin C and thiamin deficiency are rare conditions in industrialized countries. Patients undergoing AGB removal (90% for dysphagia) from 2021 to 2023 (laparoscopic 15 and robotic 5) were tested for vitamin C and thiamin levels. Twenty patients (8 m/12 f median aged 56 (range 33.6-79.4) were included. BMI at AGB removal was 39.7 (range 24.4-50.1) kg/m2. Only 20% of patients had normal thiamin levels, 30% had low levels, 20% were deficient, and 30% were critically low. Only 25% of patients had normal vitamin C levels, 40% had low levels, 25% were deficient, and 10% were critically low. One third of patients had HbA1c levels between 5.8 and 6.4 and 22% had levels >6.5; 60% of patients had hyperlipidemia. Adjustable gastric banding patients develop concerning rates of vitamin C and thiamin deficiency, and routine testing for levels is recommended.
摘要：
可调节胃束带术（AGB）后的结果不令人满意，需要移除许多设备以治疗吞咽困难。维生素C和硫胺素缺乏在工业化国家是罕见的疾病。从2021年到2023年接受AGB切除（吞咽困难占90％）的患者（腹腔镜15和机器人5）进行了维生素C和硫胺素水平测试。包括20名患者（8m/12f，中位年龄56岁（范围33.6-79.4）。去除AGB时的BMI为39.7（范围24.4-50.1）kg/m2。只有20%的患者有正常的硫胺素水平，30%的水平很低，20%是有缺陷的，和30%是非常低的。只有25%的患者维生素C水平正常，40%的水平很低，25%是有缺陷的，10%处于极低的水平。三分之一的患者的HbA1c水平在5.8和6.4之间，22%的患者的HbA1c水平>6.5；60%的患者患有高脂血症。可调节的胃束带患者会出现维生素C和硫胺素缺乏的发生率，和水平的常规测试建议。
