目的 探讨CT对术前判断食管癌可切除之价值。方法 70例经手术病理证实的食管癌病例,术前均进行CT平扫加增强检查。结果 CT表现示主动脉受侵20例和无受侵30例均手术证实,20例可疑受侵中10例手术证实受侵,10例未受侵。10例气管、支气管后壁不规则,伴腔内不突起,10例气道后壁凸面向内弧形压迹,5例肿块与气道间脂肪间隙消失,病理证实7例气道受侵,18例无受侵。结论 CF能较确切显示食管癌对相邻纵隔结构的侵犯,有助于手术可切除性的判断。
Objective To investigate the value of preoperative CT in evaluating the resection of esophageal cancer. Methods A total of 70 cases of esophageal cancer confirmed by surgery and pathology underwent CT plain scan plus enhanced examination before surgery. Results CT findings showed that 20 cases of aortic invasion and 30 cases of non-invasion were confirmed by surgery. Among the 20 suspected sutures, 10 cases were confirmed to be invasive and 10 cases were not invaded. 10 cases of trachea and bronchial wall irregular, with no bulge in the cavity, 10 cases of airway posterior wall convex inward arc-shaped pressure trace, 5 cases of fat gap between the mass and the airway disappeared, pathologically confirmed 7 cases of airway invasion, 18 cases were invaded. Conclusion CF can accurately show the violation of adjacent mediastinal structure of esophageal cancer, and it is helpful for the judgment of resectable surgery.
