目的探讨术前CT检查判断食管癌外侵气管-支气管和下肺静脉的价值。方法30例经病理学检查确诊的食管癌患者进行术前的CT检查及分析。气管-支气管受侵判别标准:气管-支气管有明显移位、受压并有管壁不规则变形或有肿物凸入气管、支气管腔内为受侵,否则为未受侵。肿瘤包绕下肺静脉或肿瘤与下肺静脉分界不清时,考虑为下肺静脉受侵。结果30例食管癌患者气管-支气管受侵CT诊断的敏感性、特异性及准确性分别为100.00%、88.00%及90.00%;下肺静脉受侵的敏感性、特异性及准确性分别为100.00%、92.86%及93.33%。结论术前CT检查判断食管癌有否外侵气管-支气管及下肺静脉价值较大。
Objective To investigate the value of preoperative CT examination in judging the invasion of esophageal cancer into the trachea-bronchus and the inferior pulmonary vein. Methods Thirty cases of esophageal cancer patients diagnosed by pathological examinations were subjected to preoperative CT examination and analysis. Tracheo-bronchial invasion criteria: Trachea-bronchial dislocation, pressure and irregular wall deformation or tumor protruding into the trachea, bronchial cavity invasion, otherwise uninvaded. When the tumor is surrounded by the pulmonary vein or the boundary between the tumor and the inferior pulmonary vein is unclear, consider the invasion of the inferior pulmonary vein. Results The sensitivity, specificity and accuracy of CT diagnosis of tracheobronchial invasion in 30 patients with esophageal cancer were 100.00%, 88.00% and 90.00%, respectively. The sensitivity, specificity and accuracy of lower pulmonary vein invasion were 100.00% respectively. 92.86% and 93.33%. Conclusions Preoperative CT examination is valuable for judging whether esophageal cancer has invasive tracheobronchial and inferior pulmonary veins.
