【摘要】 目的:探讨99m锝扫描对小儿消化系统出血,尤其是先天畸形的诊断意义。方法:对486例消化系统出血患儿行99m锝扫描检查,并对其检查结果与手术后病理检查结果作对照分析。结果:486例病人99m锝扫描阳性423例,阴性63例,经手术证实Meckel憩室382例,重复畸形38例,阳性率86.4%。63例扫描阴性的病人有5例再次出血,重复行99mTco4扫描,3例阳性,手术证实2例为Meckel憩室,1例为肠重复畸形。结论:99m锝扫描检查在对小儿消化道出血,尤其是先天畸形,具有简单,无创伤,可重复检查的优点,且阳性率较高。更多还原

【Abstract】 Objective:To study the diagnostic meaning of the 99mTco4 scanning for enteron hemorrhage,especially to intestinal duplication of child.Methods:Summarized 486 enteron hemorrhaged patient’s scanning result and contrast analysis with pathologic results.Results:In those results,the masculine results were 486,the feminine results were 63.The patients whose hemorrhage reasons that were confirmed by operation were Meckel’s diverticulum is 382,the patients whose hemorrhage reason was intestinal duplication was 38.The masculine ratio was 86.4%.63 patients whose scanning result was feminine hemorrhaged again and were scanned by 99mTco4,the masculine result was 3,the patients whose hemorrhage reason that was confirmed by operation Meckel’s diverticulum was 2,the patients whose hemorrhage reason was intestinal duplication is 1.Conclusions:The 99mTco4 scanning is worth to be extended because this method is simple,no invasive,can be repeated.更多还原
