目的评价术前 CT 判别胰头癌可切除性的方法和标准,并评估其临床意义。方法使用螺旋 CT 对24例胰头癌病人进行术前薄层多期扫描,将胰周血管受侵犯程度分为4级,结合周围组织脏器的受累情况判断胰头癌的可切除性,并与手术结果相对照。结果 24例胰头癌病人,术前15例判别可切除,实际14例得到了根治性切除,阳性准确率达93.3%,阴性准确率达100%。结论利用血管受侵犯程度分级,螺旋 CT 可以较准确的判别胰头癌的可切除性,具有重要的临床意义。
Objective To evaluate the method and criteria of preoperative CT in distinguishing resectability of pancreatic head cancer and evaluate its clinical significance. Methods Twenty-four patients with pancreatic head cancer were scanned by thin-section multi-phase spiral CT before operation. The extent of invasion of peripancreatic vessels was divided into four grades. The resectability of pancreatic ductal carcinoma was evaluated according to the involvement of surrounding organs. Contrast with the surgical results. Results Twenty - four patients with pancreatic head cancer were identified as resectable in 15 cases before operation. Radical resection was performed in 14 cases. The positive rate was 93.3% and the negative rate was 100%. Conclusion It is of great clinical significance to make use of the grading of blood vessel invasion and to determine the resectability of pancreatic cancer with accurate accuracy.
