| 目的 比较胸部螺旋CT增强扫描及微探头超声内镜(MPS)检查在评价进展期食管癌的价值。方法 32例进展期食管癌术前行CT扫描和MPS检查并与术后病理学比较。结果 CT扫描能发现82.9%的食管癌病灶,但不能准确诊断癌肿浸润深度。诊断纵隔结构受侵准确率75%,发现区域淋巴结转移敏感性91.7%, 特异性80.5%,对纵隔内远处淋巴结转移诊断准确率80%。 MPS检查能检出所有病例的进展期食管癌病灶,癌肿浸润深度诊断准确率81.5%,诊断纵隔结构受侵准确率50%,诊断区域淋巴结转移敏感性88.9%,特异性77.8%,而对纵隔内远处转移的淋巴结均未能探及。结论 CT扫描在评价纵隔内结构受侵及远处淋巴结转移的意义较大,而MPS检查在判断癌肿管腔浸润深度的准确率较高。 |

| Objective To compare enhancement CT scanning with miniatrue probe scanner (MPS) in the diagnostic value of advanced esophageal neoplasms. Methods To review the preoperation CT and MPS appearance of 32 cases of esophageal neoplasms proved by pathology. Results CT scanning depicted 82.9% focus of esophageal neoplasms, but could not accurately diagnose how deep the carcinoma infiltrated. Accuracy of invasion of mediastinum was 75%, sensitivity and specificity of CT scanning for region nodal metastases were 91.7% and 80.5%,whereas the accuracy of distant nodal metastases was 80%. All of 32 cases advanced esophageal neoplasms were identified at MPS examination, accuracy of carcinoma infiltrative depth was 81.5%, which of invasion of mediastinum was 50%, sensitivity and specificity of region nodal metastases were 88.9% and 77.8%,but distant nodal metastases in mediastinum could not be found. Conclusion Enhancement CT scanning is significant in evaluating invasion of mediastinum and distant nodal metastases, whereas the accuracy rate of diagnosis in carcinoma infiltrative depth with MPS examination is greater. |
