目的 探讨食管钡餐结合食管低张CT扫描对食管癌手术切除可行性评估的价值.资料与方法 42例食管癌患者均行食管钡餐造影及食管低张CT扫描,分析其影像表现,并与手术所见及术后标本相对照.结果食管壁厚度度≤1cm,癌肿多限于壁内浸润:壁厚2cm时,外侵率为50%;壁厚3cm时,外侵率为72%;壁厚＞3cm,外侵率为100%.癌肿与主动脉接触角度＞90°时,主动脉受侵率达83.3%.髓质型食管癌相邻气管、支气管受侵率达72.7%.结论 食管钡餐结合食管低张CT扫描可在术前正确判断食管癌切除的可能性,可减少不必要的外科手术.%Purpose To investigate the value of the feasibility assessment of resectability for esophageal carcinoma using barium meal and hypotonic esophagus CT scan. Materials and Methods 42 patients of esophageal carcinoma underwent barium meal and CT scan. Imaging findings were analyzed and compared with surgical and pathological findings. Results When the thickness of the esophageal wall ≤ 1cm, the cancer was more limited within the wall, and when the thickness was 2cm, 3cm and > 3cm, the invasion rate was 50%, 72%, and 100%, respectively. If the contact angle between the tumor and aorta was larger than 90 °, the rate of aorta involvement was about 83%. The rate of trachea and bronchus involvement in the medullary carcinoma was 73%. Conclusion The resectable possibility of esophageal carcinoma before operation can be judged by barium meal and hypotonic esophagus CT scan , which would help avoid unnecessary surgical exploration.
