小儿慢性胃炎^(99)Tc^mO_4^-固体餐胃排空检测

Analysis of gastric emptying of 99TcmO4- labeled solid meal in children with chronic gastritis

目的：通过９９ＴｃｍＯ４－标记的固体餐检测胃排空，了解小儿慢性胃炎胃运动的情况．方法：９９ＴｃｍＯ４－标记鸡肝为试餐，对２５例慢性胃炎患儿进行了核素检测分析．结果：轻度慢性胃炎患儿的胃半排空时间为６３．８６ｍｉｎ，９５％可信区间为３７．４９ｍｉｎ～９０．２２ｍｉｎ．中度慢性胃炎患儿的胃半排空时间为９５．６８ｍｉｎ，９５％可信区间为７１．８８ｍｉｎ～１１９．４９ｍｉｎ，重度慢性胃炎患儿的胃半排空时间大于１２０ｍｉｎ．结论：小儿慢性胃炎患儿的胃排空时间随病情加重而延长，不同程度病变间有显著差异．

AIM: To investigate the process of gastric emptying in children with chronic gastritis. METHODS: Twentyfive children with chronic gastritis were examined by SPECT, using 99TcmO4- labeled chicken liver as test meal. HZRESULTS: Half gastric emptying time of children with mild, moderate and severe chronic gastritis were 63.86 minutes, 95.68 minutes and >120 minutes respectively, 95% confidence interval of mild and moderate chronic gastritis group being 37.49￣90.22 minutes and 71.88￣119.49 minutes respectively. CONCLUSION: The results show that gastric emptying time of children with chronic gastritis is prolonged along with the severity of the condition and significant difference is found among mild, moderate and severe groups.
