小探头超声在食管黏膜下肿瘤诊断中的应用

Application of ultrasound miniature probe in diagnosis of esophageal submucosa tumor

目的探讨超声微探头在提高食管黏膜下肿瘤诊断率中的价值。方法利用超声微探头和自制水囊，对经常规内镜诊断为食管黏膜下肿瘤的73例患者进行超声内镜检查。结果微型超声探头检查并经病理证实的33例，术后病理诊断与超声内镜诊断符合率93．9％。结论超声微探头和自制水囊检查能清楚显示食管壁各层判断肿瘤起源及浸润层次，对食管黏膜下肿瘤的诊断有较高的临床价值。

Objective To explore the diagnostic value of ultrasound miniature probe in diagnosis of esophageal submucosa tumors, and to improve its diagnostic rate. Methods Seventy - three patients with esophageal submucosa tumors were confirmed by conventional endoscopic diagnosis, then they were examined by endoscopic ultrasonography with ultrasound miniature probe and self - made water sac. Results Thirty-three cases were examined by ultrasound miniature probe and confirmed by pathology. The coincidence of pathologic diagnosis after operation and ultrasonic endoscopic diagnosis was 93.9%. Conclusion Ultrasound miniature probe and self - made water sac can display esophagus wall clearly, and determine the origin of tumor and infiltration accurately. It has high clinical value in diagnosis of esophageal submucosa tumors.
