消化超声在上消化道黏膜下肿瘤诊治中的应用价值分析

An Analysis on Application Value of Digestion-based Ultrasonography in the Diagnosis of Upper Gastrointestinal Submucosal Tumor

[目的]研究消化超声在消化道黏膜下肿瘤诊断中的使用价值。[方法]120例疑似上消化道黏膜下肿瘤患者均于术前行消化超声评估,观察消化超声下不同病变的表现及诊断符合率。[结果]超声定位符合率为98.3%,与术中定位比较,差异无统计学差异(P>0.05);超声定性诊断符合率为95.8%,与病理诊断结果比较,差异无统计学意义(P>0.05)。消化超声下平滑肌瘤呈现出均匀低回声或弱回声光团,间质瘤呈现混合低回声。[结论]消化超声在上消化道黏膜下肿瘤诊断及病变来源判断中有较高准确性、敏感性;消化超声通过病灶回声特点较准确判断病变类型及来源,为手术治疗提供重要指导。

[Purpose ]To investigate the application value of digestion-based uhrasonography in the diagnosis for gastrointestinal submucosal tumor. [ Methods ] One hundred and twenty patients with suspected upper gastrointestinal submucosal tumor underwent preoperative digestion-based uhra- sonic evaluation. The accuracy, sensitivity and specificity of ultrasonic diagnosis and the diagnosis of lesions source were calculated based on pathologic examination results,and manifestations of different lesions under digestion-based ultrasonography were observed. [Results] Ultrasonic local- ization coincidence rate was 98.3% ,which was not significantly different with intraoperative lo- calization （P〉0.05）.Ultrasonic qualitative diagnosis coincidence rate was 95.8% ,which was not significantly different with pathological diagnosis （P〉0.05）.The leiomyoma under digestion-based ultrasonography presented uniform low echo or weak echo mass, and the mesenchymoma present- ed mixed hypoecho. [Conclusion] The digestion-based uhrasonography delivers higher accuracy and sensitivity in the diagnosis for upper gastrointestinal submucosal tumor and the differential diagnosis, and it is able to accurately determine the type and source of lesions via echo character- istics and provide important guidance for the surgical treatment.
