Evaluation Of Spiral CT To Thoracic Esophageal Cancer Surgical Resectability

Objective Patients with thoracic esophageal cancer, examine with spiral CT. Judge relationship of esophageal tumor and trachea-bronchi, the thoracic aorta and pericardial. Compare spiral CT results and surgical and pathological findings, To investigate the value of spiral CT scan in assessment of thoracic esophageal cancer surgical resectability.Methods One hundred and twenty patients with thoracic esophageal cancer proved by electronic endoscopy and biopsy underwent, chest routine and enhanced scan with 64-slice spiral CT before operation. Combine the transection image and multi-planar reformation and even virtual endoscopy technology to analyse. According to infiltrating degree of the thoracic esophageal cancer to trachea-bronchi, the thoracic aorta and pericardial, divided into easy excision type, difficult excision type and palliative resection or exploration intraoperative type. The spiral CT results were compared with surgical and pathological findings.Results One hundred and twenty patients with thoracic esophageal cancer, surgical resectionone 114, the resectable rate of esophageal cancer was 95.0% (114/120), including easy excision type 65, difficult excision type 35 and palliative resection type 14. Six patients underwent surgical exploration for tumour infiltrating surrounding structures, among them three patients diagnosis negatie, intraoperative see tumor infringe upon bronchial form esophageal tracheal fistula, surround pulmonary vein and azygous vein. A high agreement was found between CT results and intraoperative findings (Kappa=0.758, P<0.001). The sensitivity, specificity and accuracy of MPR in diagnosis outside invade of thoracic esophageal cancer are high, but no statistics differences(P>0.05).Conclusion Spiral CT can display relationship of esophageal tumor with surrounding structure, evaluate esophageal thickness, length, aortic contact angle and form of the trachea-bronchial. Computed tomography has important value in preoprative assessing of resectability esophageal carcinoma and guide clinical surgery path.
