目的分析胃肠道间叶源性肿瘤的临床病理特征,并研究超声内镜对GIMT的临床诊断作用。方法现选取2013年9月—2014年10月郑州大学附属郑州中心医院收治的胃肠道间叶源性肿瘤患者56例,分析其临床具体情况。结果 56例患者中,39例患者为GIST,病理检查确诊34例;诊断为平滑肌瘤17例,经病理诊断确诊14例,总诊断准确率为85.7%。诊断CIMT良性患者为43例,7例患者为低度恶性肿瘤或交界性肿瘤;13例恶性肿瘤患者中,病理诊断为4例为交界性,1例为GIST,超声内镜检查中确诊率为78.6%。结论超声内镜检查对临床诊断胃肠道间叶源性肿瘤具有积极的作用,配合病理特征检查可进行准确、有效的确诊。
Objective To analyze the clinicopathological features of gastrointestinal interstitial mesenchymal tumors and to study the clinical diagnosis of GIMT with endoscopic ultrasonography. Methods Fifty-six patients with gastrointestinal mesenchymal tumors who were admitted to Zhengzhou Central Hospital Affiliated to Zhengzhou University from September 2013 to October 2014 were selected, and the clinical conditions were analyzed. Results Of the 56 patients, 39 were GIST and 34 were diagnosed by pathology. 17 were diagnosed as leiomyoma, and 14 were pathologically diagnosed. The overall diagnostic accuracy was 85.7%. The diagnosis of benign and malignant CIMT patients was 43 cases, 7 cases of low-grade or borderline tumors; 13 cases of malignant tumors, the pathological diagnosis of four cases of borderline, one case of GIST, ultrasound endoscopy confirmed rate was 78.6%. Conclusion Ultrasound endoscopy has a positive effect on the clinical diagnosis of gastrointestinal mesenchymal tumors. With the examination of pathological features, accurate and effective diagnosis can be made.
