目的探讨64排螺旋CT在评估胸 段食管癌手术切除的可行性。方法 选取 医院经手术病理确诊的胸段食管癌患者39 例作为研究对象，术前均行64排螺旋CT 检查，观察两组手术分期及周围组织受侵 犯情况，并与手术病理对比。结果 与手 术病理对比，术前螺旋CT结果显示，32例 食管癌根治术、符合率为82.05%；6例食 管癌部分切除术，占15.38%，1例无法行 手术治疗，占2.56%；64排螺旋CT检查显 示，8例侵犯气管，符合率为88.89%；4 例侵犯心包，占66.67%；7例侵犯胸主动 脉，符合率为87.5%；64排螺旋CT诊断胸 段食管癌TNM分期中，Ⅰ-Ⅱ期诊断准确率 为66.67%,Ⅲ期诊断准确率为77.78%；Ⅳ 期诊断准确率为96.30%。结论 64层螺旋 CT诊断胸段食管癌患者周围组织侵犯、肿 瘤TNM分期的准确性较高，在术前确定治 疗方案中具有较高的应用价值。

Objective To explore the feasibility of 64 slice spiral CT in the evaluation of thoracic esophageal carcinoma excision. Methods A total of 39 patients with thoracic esophageal carcinoma diagnosed by surgery pathology in the hospital were selected as the research objects. All of the chosen patients received 64 slice spiral CT before operation. The surgical staging and the situation of invasion of the surrounding tissues in the two groups were observed and were compared with pathology. Results Compared with the surgery and pathology, the results of preoperative spiral CT showed that there were 32 cases of radical mastectomy and the coincidence rate was 82.05%; 6 cases of partial resection of the esophageal carcinoma and the coincidence rate was 15.38% and 1 cases not able to receive surgical treatment and the coincidence rate was 2.56%; 64 slice spiral CT showed that there were 8 cases with tracheal invasion, 4 cases of violations of the pericardium and 7 cases with invaded thoracic aorta and the coincidence rates respectively were 88.89%, 66.67% and 87.5%; In TNM staging of 64 slice spiral CT in the diagnosis of esophageal carcinoma, the diagnostic accuracy in tage I to II was 66.67%, in stge III was 77.78% and in stage IV was 96.30%. Conclusion The accuracy of 64 slice spiral CT in the diagnosis of invasion of surrounding tissues and TNM staging of patients with thoracic esophageal carcinoma is relatively higher. It is of high application value in the preoperative determination of treatment scheme.
