The role of computer tomography in esophageal cancer surgery

To investigate the role of Computer Tomography (CT) in the esophageal cancer surgery. 97 cases confirmed by pathology as esophageal cancer were retrospectively analyzed with preoperative Computer Tomography images and intraoperative situation. Tthe Computer Tomography can accurately display the thickness and length of the lesion segment esophageal wall, the relations between tumor and the aorta, the trachea, bronchus, pericardial and pulmonary vein, and local lymph node metastasis, prompt possible difficulties in surgical resection; Correctly grasp the esophageal preoperative Computer Tomography staging helps to select appropriate treatment to reduce the rate of surgical exploration. CT images is clear with high density resolution in human tissue; spiral CT-3D reconstruction technique can display clearly human body structure and relationship with the adjacent structures; the CT scan has important significance in preoperative staging of esophageal cancer; the CT scan has operation resection rate of esophageal cancer improvement.
