摘　　要：对１７例小儿消化道出血的患儿作了（９９ｍ）ＴｃＯ４腹部显像．结果显示９例手术证实为Ｍｅｃｋｅｌ憩室的患儿中８例腹部有异常放射性浓聚，１例阴性．１例肠重复畸形，其腹部也有异常放射性浓聚区．另有升结肠息肉，出血性小肠炎．慢性结肠炎等７例均呈阴性．其诊断小儿消化道出血的灵敏度、特异性及准确率分别为９０．０％、１００．０％及９４．１％，表明放射性核素显像诊断消化道出血是一种简便、安全、准确性较高的方法．Abstract ?99m)Tc-pertechnetate abdominal scintigraphy was performed in 17 children with gastrointestinal bleeding. In 9 surgically confirmed Meckel's diverticuli cases, 8 had positive imaging,1 negative.1 case of duplication cysts also had positive finding, the other 7 patients with colon polyps, hemorrhagic enteritis or Crohn's disease had negative result.The sensitivity, specificity and accuracy were 90.0%,100.0% and 94.1%,respectively.5 patients also took￣(99m)Tc-RBC scanning,bleeding sites were observed in 2 cases and the other 2 cases showed marked spleen hypertrophy.Our study indicates that radionuclide imaging (RNI) is an efficient,safe and accurate method in the diagnosis of children gastrointestinal hemorrhage.
