B型超声鉴别腹水性质的价值

为评价Ｂ型超声鉴别腹水性质的价值，观察并分析了４８例肝硬化、３６例癌性腹膜炎和１６例结核性腹膜炎共１００例腹水病人声像图６种征象。结果表明，声像图胆囊壁增厚征和肠管飘浮征是预测肝硬化漏出性腹水的良好指标，但不能排除肝硬化合并原发性肝癌腹膜转移的可能。肠管束缚征预测癌性腹水敏感性５８．３％，但特异性高达９６．９％，诊断准确性８３％。腹水分隔征常见于结核性腹水，此征有助与癌性腹水鉴别。

Value of Ultrasound for Differential Diagnosis of Ascites Nature

To evaluate the value of ultrasound examination for the differential diagnosis of various ascites,ultrasonographic findings of 100 cases with ascites including in 48 cases of liver cirrhosis, 36cases of malignant diseases and 16 cases of tuberculous peritonitis were analyzed. The results show that the sonographically thickened gallbladder wall sign and the floating bowel sign are good predictor of cirrhotic ascites,but they can not exclude liver cirrhosis complicated by primary hepatoma with peritoneal metastasis. The tethered bowel sign as a predictor of carcinomatous ascites has a sensitivity of 58. 3%,a specificity of 96. 9% and an accuracy of 83%. The septate ascites sign is more frequently seen in tuberculous peritonitis,which is useful for differentiating tuberculosis from carcinomatous ascites.
