彩色超声在胃肠道间质瘤诊断中的应用

Clinical value of color Doppler sonography in the diagnosis of gastrointestinal stromal tumor

目的:探讨彩色超声在胃肠道间质瘤(GIST)诊断中的应用价值.方法:回顾性分析经病理证实的45例GIST的超声声像图特征,将超声与手术病理结果进行对比分析.结果:超声测量肿瘤的最大径线数值病理测量方法差异无统计学意义(t=1.328,P>0.05).肿瘤的形态及内部回声与其危险性高低有关:危险性低、形态规则、内部回声均;危险性高,形态不规则,内呈现混杂回声.彩色血流分布与肿瘤危险性高低无明显相关.超声在胃GIST的诊断准确率高于肠道GIST.结论:彩色超声检查在GIST诊断中具有实用价值,结合其他检查可提高GIST诊断准确性.

AIM： To analyze the value of color Doppler sonography in the diagnosis of gastrointestinal stromal tumor （GIST）. METHODS： The color Doppler sonographic images obtained in 45 patients with pathologically confirmed GIST were analyzed retrospectively. The sonographic findings were compared with pathological results. RESULTS： There was no statistical difference in diagnostic accuracy of tumor size assessment between color Doppler sonography and pathological examination （t = 1.328, P 〉 0.05）. Tumor size, internal echo and morphology were critical factors for differentiation of low- and high-risk GIST. Color Doppler sonography has a higher accuracy in the diagnosis of GIST in the stomach than in the intestinal tract. CONCLUSION： Color Doppler sonography is an effective method for diagnosis of GIST. Color Doppler sonography in combination with other examinations may improve diagnostic accuracy in patients with GIST.
