Meckel diverticulum was diagnosed preoperatively as the cause of recurrent rectal bleeding in a 2-year-old child by means of a sodium pertechnetate Tc 99m scan. Although false-negative scans have been reported to occur in approximately 50% of all cases of Meckel diverticulum, the procedure should be considered in any case of unexplained, painless rectal bleeding, especially in pediatric patients.
通过99m锝高锝酸钠扫描，术前诊断出一名2岁儿童复发性直肠出血的病因是梅克尔憩室。尽管据报道，在所有梅克尔憩室病例中约有50%会出现假阴性扫描结果，但对于任何不明原因的无痛性直肠出血病例，尤其是儿科患者，都应考虑进行该检查。
