Laparoscopic adjustable gastric banding (LAGB), as one major bariatric surgery for treatment of obesity, results in ineffective long-term weight loss and a high reoperation rate. The objective of this study was to evaluate the long-term effects of LAGB on the weight loss outcomes and reoperation rates of obese patients with different body mass index (BMI) levels in China.
A retrospective study was performed to review the follow-up data of obese patients who underwent LAGB at Shanghai Changhai Hospital between November 2003 and May 2013. The main outcomes included weight loss, percentage excess weight loss (%EWL), reoperation rate, and reasons for reoperation.
A total of 254 LAGB procedures were performed in our hospital. By the end of May 2013, 145 Chinese patients (57.8%) were followed up, 99 patients with BMI ≥ 35 kg/m(2) (high BMI group) and 46 patients with BMI < 35 kg/m(2) (low BMI group). In the high BMI group, the mean %EWL was > 25% within 5 years postoperatively, but it decreased to less than 25% after 5 years. However, in the low BMI group, the mean %EWL at each time point was over 50%. The reoperation rate was 33.1%; it was 17.4% in the low BMI group and 34.3% in the high BMI group.
LAGB is more effective with a lower reoperation rate for obese patients with a BMI < 35 kg/m(2) compared to BMI ≥ 35 kg/m(2) in our population.
腹腔镜可调节胃束带术（LAGB）作为治疗肥胖症的一种主要减肥手术，长期减肥效果不佳且再次手术率较高。本研究的目的是评估LAGB对中国不同体重指数（BMI）水平肥胖患者减肥效果和再次手术率的长期影响。
进行一项回顾性研究，以回顾2003年11月至2013年5月期间在上海长海医院接受LAGB的肥胖患者的随访数据。主要结局包括体重减轻、超重减轻百分比（%EWL）、再次手术率及再次手术原因。
我院共进行了254例LAGB手术。截至2013年5月底，对145例中国患者（57.8%）进行了随访，其中BMI≥35 kg/m²的患者99例（高BMI组），BMI<35 kg/m²的患者46例（低BMI组）。在高BMI组中，术后5年内平均%EWL>25%，但5年后降至25%以下。然而，在低BMI组中，各时间点的平均%EWL均超过50%。再次手术率为33.1%；低BMI组为17.4%，高BMI组为34.3%。
在我们的研究人群中，与BMI≥35 kg/m²的肥胖患者相比，BMI<35 kg/m²的肥胖患者接受LAGB手术效果更佳，再次手术率更低。
