微探头超声对上消化道间叶源性肿瘤的诊断价值探讨

Endoscopic ultrasonography with miniprobe in diagnosis of upper gastrointestinal tract mesenchymal tumor

目的 探讨微探头超声对上消化道间叶源性肿瘤（GIMT）的诊断价值。方法 回顾分析38例进行微探头超声检查的GIMT患者的EUS特征，并将检查结果与术后病理结果进行对照。结果38例GIMT患者EUS诊断间质瘤25例，平滑肌瘤11例，平滑肌肉瘤2例。病理组织学及免疫组织化学检查后确诊间质瘤28例，其中中、高度恶性间质瘤6例；平滑肌瘤8例，平滑肌肉瘤1例，神经纤维瘤1例。EUS诊断准确率达89％。结论EUS能较好鉴别GIMT与其它黏膜下肿瘤，是目前诊断黏膜下肿瘤较为准确的方法。

Objective To investigate the diagnostic value of EUS with miniprobe on upper gastrointestinal tract mesenchymal tumor（GIMT）. Methods The EUS features of 38 patients with GIMT who underwent EUS with miniprobe were studied retrospectively , and the results were compared with the postoperative pathological findings. Results Among 38 GIMT cases detected by EUS, there were 25 cases of gastrointestinal stromal tumor , 11 cases of leiomyoma , and 2 cases of leiomyosareoma. Postoperative histopathological and immunohistochemical examinations confirmed 28 cases of stromal tumor. In which 6 cases were high-risk GIST, 8 cases were leiomyoma , 1 case was leiomyosarcoma , and 1 case was nettrofibroma. The accuracy of diagnosis with EUS was 89%. Conclusion EUS is an accurate method in diagnosis of submucosal tumors, which can make better differentiation diagnosis between GIMT and other submucosal tumors.
