摘要
目的：探讨高锝酸盐（99mTcO4-）腹部显像在美克尔憩室诊断中的价值。方法：利用放射性核素显像对临床诊断胃肠道出血的39例患儿行99mTcO4-腹部异位胃黏膜显像。通过手术病理、胃镜及临床治疗随访判断其符合程度。结果：该检查方法在诊断美克尔憩室中的灵敏度、特异度、准确度、阳性预测值及阴性预测值分别为：90.5%，94.4%，92.3%，95.0%，89.5%。结论：99mTcO4-腹部异位胃黏膜显像诊断美克尔憩室具有简单易行、敏感度和特异度高、无创、快速诊断等优点，可以做为临床上的首选检查方法。
Abstract
Objective: To assess the utility of technetium 99mTc-pertechnetate scintigraphy in diagnosing of the pediatric patient with gastrointestinal bleeding and suspected of having Meckel’s diverticulum. Methods: 99mTc-pertechnetate abdominal scintigraphy was undertaken in 39 children with history of gastrointestinal bleeding. The final diagnosis of all cases was proved by surgery and pathology or gastroscope or the follow-up visit. Results: In detecting Meckel’s diverticulum, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value of 99mTc-pertechnetate abdominal scintigraphy was 90.5%, 94.4%, 92.3%, 95.0% and 89.5% respectively. Conclusion: Radionuclide scintigraphy may be the first procedure to explore Meckel’s diverticulum.
