数字化小肠气钡造影在小肠病变中的诊断价值

目的 评价数字化小肠气钡造影在诊断小肠病变中的用途。方法 22例经手术病理证实的小肠病变，其中，恶性病变10例，良性病变12例，均经数字化小肠气钡造影。结果 在22例患者中，数字化小肠气钡造影正确诊断19例，1例空肠腺癌被误诊为炎症，2例空肠增殖性结核被误诊为恶性占位性病变。诊断敏感性、特异性、准确率、阳性预测值以及阴性预测值分别为80%，92%，87%，89%以及92%。结论 数字化小肠气钡造影对小肠病变具有较高的诊断与鉴别诊断能力，对临床上疑有小肠病变的患者应作为首选方法。

Usefulness of digital air-barium double contrast examination in the diagnosis of small intestine diseases

Objective To assess the usefulness of digital air-barium double contrast examination (DABDCE)in the diagnosis of small intestine diseases.Methods Twenty-two patients with surgically and pathologically proved small intestine discase which comprised 10 malignant and 12 benign cases underwent DABDCEs.Results DABDCEs correctly diagnosed 19 of 22 cases,except l jejunal adenocarcinoma misdiagnosed as inflammatory lesion and 2 jejunal hyperplastic tuberculosis misdiagnosed as malignant space-occupying lesions.The diagnostic sensitivity,specificity,accuracy,positive predictive value,and negative predictive value in the group were 80%,92%,87%,89%,and 92%,respectively.Conclusion For diagnosing small intestine diseases and differentiating their malignant from benign lesions,DABDCE has higher capability so that when patients are clinically suspected with small intestine diseases,DABDCE should be taken as an optimal protocol.
