摘要: 本文探讨彩色多普勒超声鉴别诊断胃间质瘤的临床价值。选取疑似胃间质瘤患者88例为研究对象,比较胃间质瘤和非胃间质瘤间彩色多普勒超声特征差异。经术后病理学诊断,胃间质瘤63例,非胃间质瘤25例。彩色多普勒超声诊断胃间质瘤的灵敏性、特异性、准确性、阳性预测值和阴性预测值分别为87.30%、84.00%、86.36%、93.22%和72.41%;胃间质瘤肿瘤直径、阻力指数、血流丰富比例和液化比例明显高于非胃间质瘤(P<0.05);中危和高危胃间质瘤肿瘤直径和液化比例明显高于极低和低危胃间质瘤(P<0.05)。彩色多普勒超声在诊断胃间质瘤中有一定价值。

Abstract: The purpose of this study was to investigate the clinical value of color Doppler ultrasound in differential diagnosis of gastric stromal tumor. A total of 88 patients with suspected gastric stromal tumors were selected as the study subjects. The differences of color Doppler ultrasound characteristics between gastric stromal tumors and non gastric stromal tumors were compared. Postoperative pathological diagnosis revealed 63 cases of gastric stromal tumor and 25 cases of non-gastric stromal tumor. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of color ultrasound in the diagnosis of gastric stromal tumor were 87.30%, 84.00%, 86.36%, 93.22% and 72.41%, respectively. The tumor diameter, resistance index, blood flow enrichment ratio and liquefaction ratio of gastric stromal tumor were significantly higher than those of non-gastric stromal tumor (P<0.05). The tumor diameter and liquefaction ratio of medium-risk and high-risk gastric stromal tumors were significantly higher than those of extremely low and low-risk gastric stromal tumors (P<0.05). Color Doppler ultrasound has certain value in the diagnosis of gastric stromal tumor.
