目的 探讨增强CT在食管癌术前 分期及切除可行性分析中的应用价值。方 法 选取44例食管癌患者为研究对象,均 予以术前增强CT检查和手术病理检查。 以病理检查为依据，评估增强CT对食管 癌术前T、N分期的准确性；分析两种检 查方法诊断肿瘤浸润及淋巴结转移的一 致性。结果 以病理检查结果为金标准， 增强CT对食管癌术前T分期诊断准确性为 70.5%(31/44)，对N分期诊断准确性为 68.2%(30/44)；对食管癌肿瘤浸润的诊断 准确性为65.9%(29/44)，对淋巴结转移的 诊断准确性为68.2%(30/44)。结论 增强 CT在食管癌术前分期及手术可切除性评估 工作中均有一定应用价值，于患者病情评 估及后续治疗工作选择有利。

Objective To investigate the value of enhanced CT in the diagnosis of preoperative staging of esophageal carcinoma and evaluation of the feasibility of resection. Methods 44 cases of patients with esophageal carcinoma were enrolled in the study. All patients were examined with enhanced CT and surgery and pathology. With the results of pathological examination as the basis, the accuracy rates of enhanced CT in the diagnosis of T and N stage of esophageal carcinoma were evaluated, and the consistency of the two methods in the diagnosis of tumor invasion and lymph node metastasis was analyzed. Results With the results of pathological examination as the gold standard, the accuracy rates of enhanced CT in the diagnosis of preoperative T stageand N stage of esophageal carcinoma were 70.5% (31/44) and 68.2% (30/44), respectively. The accuracy rates in diagnosis of esophageal carcinoma invasion and lymph node metastasis were 65.9% (29/44) and 68.2% (30/44), respectively. Conclusion Enhanced CT can be used to diagnose the preoperative stage of esophageal carcinoma and evaluate the feasibility of resection, which is conductive to evaluating the condition of patients and further treatment.
