To obtain information on possible determinants of weight loss after horizontal gastroplasty, pouch emptying was prospectively investigated in 27 morbidly obese patients. A scintigraphic method was used. Examinations were carried out every 6 months until 2 years after surgery. Pouch emptying was described by means of delay, time until half emptying, mean transit time, and emptying rate. The measures all showed a significant (p less than 0.05) acceleration of pouch emptying during the first 6 months after gastroplasty. Thereafter pouch emptying was unaltered. No significant association could be detected between measures of pouch emptying and weight loss. From calculation of 95% confidence intervals for coefficients of correlation it proved very unlikely that pouch emptying is an important determinant of weight loss.
为获取有关水平胃成形术后体重减轻可能的决定因素的信息，对27例病态肥胖患者的胃袋排空情况进行了前瞻性研究。采用了闪烁扫描法。每6个月进行一次检查，直至术后2年。通过延迟时间、半排空时间、平均通过时间和排空率来描述胃袋排空情况。所有测量指标均显示，胃成形术后的前6个月，胃袋排空显著加快（p<0.05）。此后，胃袋排空情况未发生改变。未发现胃袋排空指标与体重减轻之间存在显著关联。通过计算相关系数的95%置信区间发现，胃袋排空极不可能是体重减轻的重要决定因素。
