彩阶B超在超声内镜诊断胃胆疾病中的价值

Valve of color scale ultrasound in the EUS diagnosis of stomach and gallbladder diseases

本文报道采用阶B超与超声内镜联机,对156例胃胆病变(胃癌4例,胃溃疡40例,胆囊结石28例,胆囊息肉20例,胆囊肌腺瘤4例)进行超声内镜检查及黑白灰阶图像的彩色显示。全部病例均有手术与病理对照。结果显示:良性胃溃疡的平均色量级高于胃癌(P<0.01);胆囊结石比胆囊息肉提高近2个色量级(P<0.01);B彩能不同程度地提高病灶的清晰度;B彩对病变的诊断准确率与黑白灰阶显示的结果相近,统计学无显著差异。

With the method of endoscopic ultraso-nography (EUS) and color scale untrasound. 156 patients with stomach and gallbladuer diseases were examined with EUS and color scale ultrasound. Comparison of the EUS and color scale ultrasound with the pathological changes was done. The results -indicate that: the mean color quantity sacle of benign gastric ulcer was higher than gastric cancer (p<0.01). The gallbladder stone was two color quantity scale higher the polypoid lesion of gallbladder (p<0.01). The color scale ultrasound can improve the cleardegree of lesion pictures. The correct rates of diagnosis were no significant differences between color scale ultrasound and white-black ultrasound.
