【摘要】:回顧性分析78例經手術病理證實的胃腸道間質瘤(GIST)超聲表現,術后證實超聲測量瘤體大小與手術病理測量結果之間差異無統(tǒng)計學意義;對GIST的聲像圖進行大小、形態(tài)、邊界、內部有無壞死液化、血流情況、周圍臟器有無浸潤和轉移等6個方面進行描述,根據Fletcher原則將GIST分為低危組和中高危組,除血流信號豐富程度與腫瘤侵襲危險性分級之間差異無統(tǒng)計學意義外,瘤體大小、形狀規(guī)則情況、邊界和瘤體內液化壞死等超聲表現與腫瘤侵襲危險性之間均存在相關性(P0.01)。飲水后GIST的定位準確率為84.85%,高于飲水前的定位準確率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%).
