摘　　要：目的分析白线疝的超声表现特点，评价超声诊断白线疝的临床应用价值。方法临床拟诊为白线疝的患者28例，术前均行腹壁超声检查，并与术中所见及病理结果进行对比分析。结果与病理结果比较，术前超声诊断白线疝15例，误诊3例，漏诊5例，正确排除白线疝5例。15例白线疝患者均为可复性疝，腹白线缺损0．5～4．5cm，腹压改变时可见疝内容物通过缺损处往返移动。与手术病理结果比较，超声检查白线疝敏感性75．0％，特异性62．5％，误诊率37．5％，漏诊率25．0％，准确率71．4％，阳性预测值83．3％，阴性预测值50．0％，阳性似然比2．0，阴性似然比0．4，尤登指数0．375。结论腹壁包块穿越白线并可见白线缺损是超声诊断白线疝的重要依据。对于小的白线疝，应以白线为参照，仔细观察腹壁包块与白线的解剖关系，以提高诊断准确率。Objectives To analyze the ultrasonographic characteristics of linea alba henia and to evaluate its clinical value.Methods Twenty-eight patients with clinical impression of linea alba henia were examined by uhrasonography before the operation.The uhrasongraphic fndings and pathological results were comparatively analyzed.Results Fifteen patients were diagnosed as linea alba henia by uhrasongraphy before the operation.Three cases were misdiagnosed, 5 cases missed, and 5 cases were precluded correctly.The linea alba henia in the 15 patients was reducible and the defects of linea alba ranged from 0.5 to 4.5 cm. The hernial contents moved back and forth through the defects with the change of abdominal pressure.Compared with pathological results, the sensitivity, specificity, misdiagnostie rate, missed diagnostic rate, accuracy, positive predictive value, negative predictive, positive likelihood ratio, negative liklihood ratio and the Youden index were 75.0%, 62.5%, 37.5%, 25.0%, 71.4%, 83.3%, 50.0%, 2.0,0.4 and 0.375, respectively.Conclusion The important evidence for ultrasonography to diagnose linea alba hernia is finding abdominal mass crossing the linea alba and the defect of linea alba can be seen.For little linea alba henia, the anatomic relationship between the abdominal mass and the 1inca alba will help improve the diagnostic accuracy.
