【摘要】：回顾性分析78例经手术病理证实的胃肠道间质瘤(GIST)超声表现,术后证实超声测量瘤体大小与手术病理测量结果之间差异无统计学意义;对GIST的声像图进行大小、形态、边界、内部有无坏死液化、血流情况、周围脏器有无浸润和转移等6个方面进行描述,根据Fletcher原则将GIST分为低危组和中高危组,除血流信号丰富程度与肿瘤侵袭危险性分级之间差异无统计学意义外,瘤体大小、形状规则情况、边界和瘤体内液化坏死等超声表现与肿瘤侵袭危险性之间均存在相关性(P0.01)。饮水后GIST的定位准确率为84.85%,高于饮水前的定位准确率68.33%(P0.01)。
[Abstract]:The ultrasonographic findings of 78 cases of gastrointestinal stromal tumors (GIST) proved by operation and pathology were retrospectively analyzed. There was no significant difference between the size of the tumor measured by postoperative ultrasound and the results of pathology, and the size, shape and boundary of the sonogram of GIST were analyzed. The internal necrosis and liquefaction, blood flow, infiltration and metastasis of surrounding organs were described. According to the Fletcher principle, GIST was divided into low risk group and middle high risk group. The size and shape of the tumor were regular except that there was no significant difference between the abundance of blood flow signal and the grade of tumor invasion risk. There was a correlation between ultrasonic features such as boundary and necrosis of tumor and the risk of tumor invasion. The accuracy of GIST localization after drinking water was 84.85, which was higher than that before drinking water (68.33%).
