胃肠道间叶性肿瘤121例内镜超声诊断分析

Analysis of 121 cases of gastrointestinal mesenchymal tumors by miniprobe endoscopic ultrasonography

目的探讨小探头内镜超声检查术(miniprobe endoscopic ultrasonography,mEUS)对胃肠道间叶性肿瘤的诊断价值。方法对我院胃肠道间叶性肿瘤患者121例进行mEUS检查并与病理结果对照。结果经普通病理、免疫组化证实的121例胃肠道间叶性肿瘤(65例胃肠间质瘤,51例平滑肌瘤,5例平滑肌肉瘤),mEUS诊断102例,定性诊断准确率为84.29%,定位诊断准确率为95.86%,良恶性鉴别诊断准确率为75%。结论 mEUS既能显示胃壁各层,又能反映肿瘤浸润胃壁的深度,对于胃肠道间叶性肿瘤的诊断具有一定的价值。

Objective To evaluate the diagnostic value of miniprobe endoscopic ultrasonography（mEUS）for gastrointestinal mesenchymal tumors.Methods We compared miniprobe endoscopic ultrasonography（mEUS）and pathological results of 121 cases of gastrointestinal mesenchymal tumors（GIMT）.Results Among the 121 cases of conventional pathology plus immunohistochemistry confirmed GIMT,there were 65 cases of gastrointestinal stromal tumors,51 cases of leiomyoma and 5 cases of leiomyosarcoma,among which 102 cases were diagnosed by mEUS.The qualitative diagnostic accuracy of mEUS was 84.29%,the localization diagnostic accuracy of mEUS was 95.86%,and the accuracy of differential diagnosis between benign and malignancy was 75%.Conclusions As mEUS can visualize gastric wall layers while detect depth of tumor invasion,it is of certain diagnostic significance for GIMT.
