摘要
目的:探讨腹部矢状位CT扫描在新生儿先天性肛门直肠闭锁中的应用价值。方法:对5例先天性肛门直肠闭锁的新生儿均于术前行倒立侧位腹部平片、B超检查和腹部CT矢状位扫描,对5例先天性肛门直肠闭锁的新生儿于术前仅行腹部CT矢状位扫描,并分别测量闭锁高度,分析3种检查方法的测量结果与手术测量结果的相关性。结果:10例CT均清晰显示闭锁盲端。CT和B超测量结果与术中测值的相关系数分别为0.988和0.991,相关性非常显著(P<0.01)。平片测值与术中测值的相关系数为0.635,无显著相关(P>0.05)。结论:腹部矢状位CT判断闭锁高度的准确性与B超相似,明显高于常规X线检查,可作为先天性肛门直肠闭锁的一种选择性检查手段。
Objective： To investigate the clinical application of sagittal abdominal CT scan in determination of neonatal congenital anorectal atresia. Methods： Preoperative examinations, including leteral up-side-down abdominal plain film, ultrasound and sagittal abdominal CT scan, were performed in 5 neonates with congenital anorectal atresia. The distance between the atresic pouch and skin was measured with the three imaging modalities, and correlated respectively with the results obtained during operation. Results： The atresic pouch was observed distinctively on CT images in all 5 cases. The measurement results derived by CT and ultrasound were well correlated with that derived during operation, with a correlation coefficient of 0.988 for CT and operation, and 0.991 for ultrasound and operation. There was no significant correlation between the measurement results derived by plain film and during operation, with a correlation coefficient of 0.635. Conclusion： Sagittal abdominal CT scan, as accurate as ultrasound and more accurate than plain film for determination of the atresic level, could be used as a choice of imaging modality in neonatal congenital anorectal atresia.
