超声对鉴别腹水性质的价值

The value of ultrasonography in the differential diagnosis of ascites

目的评价经腹部二维超声及彩色多普勒超声鉴别腹水性质的价值。方法73例腹水患者均经二维超声及彩色多普勒超声检查,并与手术病理或活检对照。结果73例腹水患者中,恶性腹水12例,良性腹水61例,超声诊断准确率为89%。在声像图上,肠管束缚征、腹水浑浊及网膜饼增厚征多见于恶性腹水,而胆囊壁增厚征与肠管浮游征则多见于良性腹水。结论良性与恶性腹水的声像图征象有明显不同,因此,超声检查是鉴别腹水性质的主要方法。

Objective To evaluate the value of ultrasound examination in the differential diagonosis of ascites.Methods Seventy- three patients with ascites underwent two- dimensional ultrasound and color Doppler ultrasonography.The ultrasonographic findings in all patietns were compared with surgical pathology or biopsy.Results Among 73 patients with ascites there were 12 cases of malignant ascites and 61 cases of benign ascites.The diagnostic accuracy of ultrasonography was 89 % .On ultrasonographic images,tethered bowel sign, turbid ascites and thickened omentum- biscuit sign were more frequently seen in malignant ascites whereas thickened gallbladder wall sign and floating bowel sign were frequent in benign ascites.Conclusion The ultrasonographic findings of benign and malignant ascites have obvious differences and therefore ultrasound examination can be taken a main means for differentiating the quality of ascites.
