Application of sagittal abdominal CT scan in determination of neonatal congenital anorectal atresia / 重庆医科大学学报

ABSTRACT

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.
