However, less data is available regarding weight change after device removal and possible predictors for weight loss. This is a retrospective chart review of all patients who had DJBL inserted at the University Hospital Zurich between December 2012 and June 2015. A total of 27 patients had DJBL insertion. The median BMI at baseline was 38.5 (34.0\u201342.2)\u00a0kg\/m<jats:sup>2<\/jats:sup>. In the 24 patients with DJBL treatment &gt;3\u00a0months (failed implantation or early removal due to side effects in 3 patients), the mean duration of implantation was 42.9\u2009\u00b1\u200913.1\u2009weeks. During the treatment, the mean total body weight loss (%TBWL) was 15.0\u2009\u00b1\u20098.3%. Fifteen patients had long\u2010term follow\u2010up data available (mean duration of follow\u2010up 4.0\u2009\u00b1\u20090.9\u2009years). The mean weight change was 12.7\u2009\u00b1\u200912.8\u00a0kg, corresponding with a mean % weight regain of 13.3\u2009\u00b1\u200913.3%. Five patients (33.3%) subsequently underwent bariatric surgery. In patients with class I obesity (BMI &lt;35\u2009kg\/m<jats:sup>2<\/jats:sup> at baseline), 4 out of 6 (66.7%) had a stable weight or only a weight regain &lt;7%.
