胆管梗阻性疾病的超声特点及诊断

The Ultrasonic Feature and Diagnosis of Biliary Obstructive Disease

目的探讨胆管梗阻性疾病声像图特点及超声诊断。方法应用超声检查56例胆管梗阻性疾病与术后病理对照,对不同类型梗阻的声像图变化及个别病例误诊原因进行分析。结果对梗阻部位超声诊断有一定的特异性,能够做出一个基本的判断;但对梗阻的病因诊断不具备特异性,还需要其他检查手段加以鉴别,超声诊断与术后病理诊断符合率为94.3%,误诊率为5.7%,结论超声在诊断胆管梗阻性疾病方面,具有其他辅助检查所不具备的优势,是一种简单、有效的检查方法。

Objective To explore ultrasonographic feature and the ultrasonic diagnosis of biliary obstruction.Methods 56 cases of such patients were examed by ultrasonography.The results were contrasted with postoperative pathology.To analyze the different types of ultrasonographic changes and individual misdiagnosed reasons.Results Ultrasonic diagnosis has determinate specificity in obstruction aera and it can make a basic judgment.However,it has not specific diagnosis for the cause and need other inspection method to differentiate.The accordance rate of ultrasound diagnosis and postoperative pathologic diagnosis was 94.3%,the misdiagnosis rate was 5.7%.Conclusion Ultrasound has advantages to other auxiliary examination in the diagnosis of biliary obstruction disease and it is a simple and effective method.
