Intragastric balloon (IGB) use is indicated for patients whose BMI precludes the option of bariatric surgery or who need to lose weight prior to undergoing surgery. It is a minimally invasive procedure and currently there are two main models of IGBs in use, the non-adjustable intragastric balloon (NIB), implanted for six months, and the adjustable intragastric balloon (AIB), implanted for up to 12 months.
Analyze clinical characteristics between patients receiving non-adjustable gastric balloon and the adjustable (prolonged implantation) intragastric balloon.
This was a cross-sectional study of 470 patients diagnosed as obese or overweight who had balloon implantation from October 2011 to July 2018. The associations between percentage excess weight loss versus clinical and demographic variables were calculated using the chi-squared test. Independent samples were submitted to the Student's t test to determine the quantitative variables, with a confidence interval of 95%. Calculation of excess weight was based on an estimated ideal weight that would correspond to a BMI of 24.99 kg/m2.
A total of 414 patients completed the treatment achieving an average total body weight loss (%TBWL) of 15.4±7 with the NIB and 15.5±9.6 with the AIB. Overweight patients achieved higher excess weight loss (%EWL) values using AIBs (157.2±82.5) and obese patients did so with NIB use (56±29.7). Women achieved higher %EWL values (65.6±62.2) than men (48±27.1). Individuals who attended >4 consultations with a nutritionist (60.8%) achieved TBWL >18%. All of those P-values were <0.001.
Obese individuals and women registered the greatest weight losses. Overweight patients achieved greater losses using AIB and obese patients did so using NIBs. NIB use was associated with higher EWL percentages. Nutritional accompaniment had a positive impact on the %TBWL.
胃内球囊（IGB）适用于身体质量指数（BMI）使其无法选择减肥手术或需要在手术前减重的患者。这是一种微创手术，目前使用的主要有两种胃内球囊型号，即植入期为6个月的不可调节胃内球囊（NIB）和植入期最长为12个月的可调节胃内球囊（AIB）。
分析接受不可调节胃内球囊和可调节（延长植入期）胃内球囊患者的临床特征。
这是一项横断面研究，研究对象为2011年10月至2018年7月期间诊断为肥胖或超重且接受了球囊植入的470例患者。使用卡方检验计算超重减轻百分比与临床和人口统计学变量之间的关联。将独立样本进行学生t检验以确定定量变量，置信区间为95%。超重的计算基于估计的理想体重，该理想体重对应BMI为24.99kg/m²。
共有414例患者完成治疗，使用NIB的患者平均总体重减轻（%TBWL）为15.4±7，使用AIB的患者为15.5±9.6。超重患者使用AIB时超重减轻（%EWL）值更高（157.2±82.5），肥胖患者使用NIB时超重减轻值更高（56±29.7）。女性的%EWL值（65.6±62.2）高于男性（48±27.1）。与营养师进行超过4次咨询的个体（60.8%）的TBWL>18%。所有这些P值均<0.001。
肥胖个体和女性体重减轻最多。超重患者使用AIB减重更多，肥胖患者使用NIB减重更多。使用NIB与更高的EWL百分比相关。营养支持对%TBWL有积极影响。
