BACKGROUND
Gastric emptying scintigraphy has become the gold standard, by excellence, in gastric emptying studies. This method must be standardized for the correct interpretation of results. The ideal protocol must be performed with an egg sandwich or egg white poder, both labeled with 99mTc sulphur colloid. The aim of this study was to standardize and determine the protocol with99m Tc sulphur colloid incorporated in egg white and compare it with a hamburger labeled with 99mTc sulphur colloid as well.
METHODS
We studied 30 patients who underwent gastric emptying scintigraphy with the two aforementioned meals.
RESULTS
Emptying percentages and retention with both meals were similar within an hour and two; however, statistical significance arose until the third hour with a p value of 0.26 by using Student's t for independent samples.
CONCLUSIONS
Gastric emptying studies in both protocols where similar with normal ranges. The egg white ingested must be consistent for reproducible results in gastric motility disease, like organoleptic and volume characteristics.
背景
胃排空闪烁扫描术已成为胃排空研究的卓越金标准。该方法必须标准化，以便正确解读结果。理想的方案应使用均标记有99mTc硫胶体的鸡蛋三明治或蛋清粉进行。本研究的目的是标准化并确定含99mTc硫胶体的蛋清方案，并将其与标记有99mTc硫胶体的汉堡进行比较。
方法
我们研究了30例接受上述两种餐食胃排空闪烁扫描术的患者。
结果
两种餐食在1小时和2小时内的排空百分比和滞留情况相似；然而，直到第3小时才出现统计学显著性，使用独立样本的学生t检验，p值为0.26。
结论
两种方案中的胃排空研究结果与正常范围相似。在胃动力疾病中，为获得可重复的结果，摄入的蛋清必须保持一致，如感官和体积特征。
