目的探讨CT在食管癌手术前应用的临床意义。方法 2011年8月至2012年8月期间,我院经纤支镜、病理检查确诊的30例食管癌患者,术前全部给予胸部、上腹部的CT扫描检查,对其影像学资料,进行回顾性分析。结果 30例食管癌患者均为中晚期食管癌,主要位于胸中段,绝大多数为鳞癌。CT扫描可见食管壁僵硬,并伴有不规则增厚,管腔狭窄,甚至闭塞,病变近段管腔可出现不同程度的扩张、积气、积液等,主要侵犯气管和主动脉,可能伴有纵隔淋巴结、纵隔下淋巴结肿大,甚至肝、肺转移。结论术前CT检查能够准确地掌握肿瘤病变程度,以及转移情况,为食管癌手术治疗提供客观的理论依据,值得临床推广。 Objective To investigate the clinical significance of preoperative CT application in esophageal cancer. Methods From August 2011 to August 2012, 30 cases of esophageal cancer patients diagnosed by bronchoscopy and pathological examination in our hospital were all given preoperative CT scans of the chest and upper abdomen, and their imaging data were reviewed. Sexual analysis. Results All 30 patients with esophageal cancer were middle to advanced esophageal cancers, which were mainly located in the middle thoracic region. The vast majority were squamous cell carcinomas. The CT scan shows that the esophageal wall is stiff, with irregular thickening, narrow lumen, or even occlusion. The proximal lumen of the lesion can have different degrees of expansion, gas accumulation, effusion, etc., mainly invading the trachea and aorta. Associated with mediastinal lymph nodes, submucosal lymph nodes, and even liver and lung metastases. Conclusion Preoperative CT examination can accurately grasp the degree of tumor lesions and metastasis, provide objective theoretical basis for surgical treatment of esophageal cancer, and it is worthy of clinical promotion.
