To determine the sensitivity and specificity of computed tomography scan for diagnosing small bowel obstruction among children.
The retrospective diagnostic test accuracy study was carried out at the Aga Khan University Hospital, Karachi, and comprised data of all patients aged 2-16 years who presented with clinical features of small bowel obstruction and underwent computed tomography scan of abdomen from January 2001 to December 2015Data was analyzed using SPSS19.
Of the 98 subjects, 65(66.0%) were males and 33(34.0%) were females. Overall mean age of the patients was 7.67±4.33 years and mean duration of symptoms was 2.84±1.17 days. Sensitivity, specificity, positive and negative predictive values as well as accuracy of computed tomography scan was 97.4%, 81.8%, 94.9%, 90.0% and 93.9% respectively.
CT scan was found to have a high sensitivity, fairly good specificity and accuracy in revealing small bowel obstruction. However, the scan is known to have its limitations in sub-acute intestinal obstruction and primary peritonitis.
确定计算机断层扫描在诊断儿童小肠梗阻方面的敏感性和特异性。
在卡拉奇的阿迦汗大学医院开展回顾性诊断试验准确性研究，纳入2001年1月至2015年12月期间所有年龄在2至16岁、有小肠梗阻临床特征并接受腹部计算机断层扫描的患者数据。使用SPSS19进行数据分析。
98名受试者中，65名（66.0%）为男性，33名（34.0%）为女性。患者的总体平均年龄为7.67±4.33岁，平均症状持续时间为2.84±1.17天。计算机断层扫描的敏感性、特异性、阳性和阴性预测值以及准确性分别为97.4%、81.8%、94.9%、90.0%和93.9%。
CT扫描在显示小肠梗阻方面具有高敏感性、相当好的特异性和准确性。然而，已知该扫描在亚急性肠梗阻和原发性腹膜炎方面存在局限性。
