摘要
目的评价螺旋CT扫描对结肠癌诊断和分期的价值。方法对36例经手术病理证实的结肠癌(升结肠癌13例,横结肠癌5例,降结肠癌8例,乙状结肠癌10例)的CT表现进行回顾性分析,并将其术前分期与术后病理分期进行比较。结果在CT像上,肿瘤主要表现为含小气泡的软组织肿块或肠侧壁肿块影,肠壁肿块形态为环形、半环形、管形、椭圆形和三角形,肠壁浆膜面光滑或不规则、毛糙,病变与邻近组织器官粘连、侵犯,淋巴结肿大及远处转移。按照改良Dukes方法CT分期为A期2例,B期11例,C期17例,D期6例,CT分期与手术分期符合率为94%。结论螺旋CT对结肠癌诊断与分期价值较高,对临床手术及治疗起重要指导作用。
Objective To evaluate the applied value of spiral CT scans in the diagnosis and staging of the colonic carcinoma. Methods CT findings of 36 patients with surgically and pathologically proved colonic carcinoma which comprised 13 ascending colon-,5 transver colon-,8 descending colon-,and 10 sigmoid colon carcinomas were analyzed retrospectively. The preoperative CT staging was compared with that of postoperative pathology. Results Spiral CT scans showed that the lesions of colonic carcinoma mainly appeared as soft tissue mass shadows with small air bulb or intestinal side wall mass shadows. The shape of intestinal wall masses were varied,such as circular,semicircular,tubular,oval,and triangular etc. The serosal surfaces of the intestinal walls were smooth or coarse or associated with adhesion between the lesions and neighbor organs and lymph node enlargement or remote metastasis. According to Duke＇s staging way,the lesions of A stage were found in 2 cases,B stage in 11,C stage in 17,and D stage in 6. Compared with postoperative pathologic staging,the accurate rate of preoperative CT staging was 94%.Conclusion Spiral CT scans play an important role in the diagnosis and staging of the colonic carcinoma.
