螺旋CT对不可切除的胰腺癌诊断价值的探讨

目的探讨不能手术切除的胰腺癌CT表现及诊断标准：方法同顾性分析17例经手术、病理证实不能手术切除之胰腺癌的主要CT表现，对其增强特点，胰周脂肪、血管，临近器官、转移特点及扫描方法进行重点分析。结果胰腺癌不可切除的征象有以下几点：胰周血管受侵，肝转移及腹膜转移，临近器官受侵，远处淋巴结转移以及胰周脂肪层模糊同时伴有其他不可切除征象。结论螺旋CT增强扫描可以准确评估肿瘤侵犯范围、程度、以及转移情况，对血管受侵的显示尤为清晰。因此螺旋CT检查对判断胰腺癌是否可以切除具有重要意义。

An evaluation of spiral CT scan in diagnosis of unresectable pancreatic carcinoma

Objective To investigate the spiral CT findings and diagnostic criteria of unresectable pan-creatic carcinoma. Methods The spiral CT findings of 17 cases of pancreatic carcinoma, confirmed by surgery and histo-pathologic examinations, were retrospectively studied. Factors like peripancreatic vasculars and fat tissue, metastases or adjacent involvemnet, and the protocol of the scan were carefully evaluated. Results The CT manifestations of unresectable pancreatic carcinoma included: peripancreatic vascular involvement, metastasis found liver and peritoneum, adjacent organ involvement, distant metastatic lymphadenopathy and invasion of peripancreatic fat plane accompanied with other signs of unresectable lesion revealed in the same evaluation. Conclusion Spiral CT scan accurately evaluates the range, degree of tumor, metastatic lesions and especially the peripancreatic vascular involvement. Spiral CT scan is a valuable in determining the resectability of pancreatic cancer.
