胃肠道间质瘤的超声诊断价值

The Value of Ultrasonography in the Diagnosis of Gastrointestinal Stromal Tumors

目的:研究分析超声在胃肠道间质瘤(GIST)诊断中的价值。方法:回顾分析83例经手术病理证实的胃肠道间质瘤的超声表现及诊断结果,并与CT诊断结果对照。结果:病理诊断良性6例,交界性16例,恶性61例。超声检查在胃、十二指肠及小肠GIST的诊断准确率分别为82.5%、50.0%和45.5%。声像图表现中,病灶大小及内部是否出现无回声区是判断肿瘤良恶性的重要依据。CT和超声检查在GIST的定位、定性准确率方面无明显差异。结论:超声检查在胃肠道间质瘤的诊断中具有重要价值,可为临床治疗方案的选择提供重要依据。

Objective：To analyze the value of ultrasonography in the diagnosis of gastrointestinal stromal tumors （GIST）. Methods：The sonographic characterization of 83 GIST patients confirmed by pathology were analyzed retrospectively and compared with CT results. Results：In 83 GIST patlents, the final diagnosis included benign （n=6）, borderline （n=16） and malignant （n=61）. The accuracy of ultrasonography in the diagnosis of GISTs was 82.5% in stomach, 50.0% in duodenum and 45.5% in intestine respectively. The size and the internal echogenicity were critical in differentiating benign and malignant GISTs. There was no statistical difference of diagnostic accuracy between ultrasonography and CT in the diagnosis of GISTs. Conclusion：Ultrasonography is valuable in the diagnosis of GISTs, which is helpful in clinical management.
