After bariatric surgery lifelong follow-up is recommended. Evidence of the consequences and reasons for being lost to follow-up (LTFU) is sparse. In this prospective study follow-up data of all patients who underwent bariatric surgery between 2008 and 2017 at a certified obesity centre were investigated. LTFU patients were evaluated through a structured telephone interview. Overall, 573 patients (female/male 70.9%/29.1%), aged 44.1 ± 11.2 years, preoperative BMI 52.1 ± 8.4 kg/m underwent bariatric surgery. Out of these, 33.2% had type 2 diabetes mellitus and 74.4% had arterial hypertension. A total of 290 patients were LTFU, of those 82.1% could be reached. Baseline characteristics of patients in follow-up (IFU) and LTFU were comparable, but men were more often LTFU ( = 0.01). Reported postoperative total weight loss (%TWL) and improvements of comorbidities were comparable, but %TWL was higher in patients remaining in follow-up for at least 2 years ( = 0.013). Travel issues were mentioned as the main reason for being LTFU. A percentage of 77.6% of patients reported to regularly supplement micronutrients, while 71.0% stated regular monitoring of their micronutrient status, mostly by primary care physicians. Despite comparable reported outcomes of LTFU to IFU patients, the duration of the in-centre follow-up period affected %TWL. There is a lack of sufficient supplementation and monitoring of micronutrients in a considerable number of LTFU patients.
减重手术后建议进行终身随访。关于失访（LTFU）的后果和原因的证据很少。在这项前瞻性研究中，调查了 2008 年至 2017 年期间在一家认证的肥胖中心接受减重手术的所有患者的随访数据。通过结构化电话访谈评估 LTFU 患者。共有 573 名（女性/男性 70.9%/29.1%）患者，年龄 44.1 ± 11.2 岁，术前 BMI 52.1 ± 8.4 kg/m 接受了减重手术。其中，33.2%患有 2 型糖尿病，74.4%患有动脉高血压。共有 290 名患者失访，其中 82.1%能够联系上。在随访（IFU）和失访（LTFU）患者中，基线特征具有可比性，但男性更常失访（= 0.01）。报告的术后总体重减轻（%TWL）和合并症的改善具有可比性，但在至少随访 2 年的患者中，%TWL 更高（= 0.013）。旅行问题被认为是失访的主要原因。77.6%的患者报告定期补充微量营养素，而 71.0%的患者表示定期监测其微量营养素状况，主要由初级保健医生进行。尽管 LTFU 患者的报告结果与 IFU 患者具有可比性，但中心随访期的持续时间会影响%TWL。在相当多的 LTFU 患者中，微量营养素的补充和监测不足。
