消化道穿孔超声检查临床应用的评价

The Evaluation of Ultrasonogrophy in the Diagnosis of Digestive Tract perforation

目的：为了评价普通超声在诊断消化道穿孔中的价值。方法：１１９例经手术证实的消化道穿孔病人，术前行Ｘ线检查，６８例术前行普通超声检查。将所有的检查结果进行回顾性评价及对比分析。结果：行Ｘ线检查的１１９例病人，９１例为阳性，符合率为７５％（９１／１１９），假阴性２８例，占２５％（２８／１１９）。行超声检查的６８例中阳性者占７８％（５５／６８）。其中１０例超声发现膈下气体而Ｘ线为阴性。结论：普通超声在诊断消化道穿孔中可弥补Ｘ线的不足，在急腹症的鉴别诊断中具有重要地位。

Objective:The purpose of is study was to evaluate the value of ultrasonography in the diagnosis of digestive tract perforation.Method:119 patients with digestive tract perforation verified by operation were examined by X ray.Of these 119 patients,68 were examined by ultrasonography.All these examinations were retrospectively evaluated and comparably analysed.Result:119 patients were examined by X ray.Of these 119 patients,91 were positive,and the positive value was 75%(91/119);28 were pseudo negative (25%,28/119).68 patients were examined by ultrasonography and the positive value was 78%(55/68).Of the 55 patients who were exactly diagnosed by ultrasonography,10 were not to be diagnosed by x ray.Conclusion:Ultrasonography can complement the defect of x ray in the diagnosis of digestive tract perforation,and is very useful in the differential diagnosis of digestive tract perforation.
