目的 :评估回盲部结肠癌的CT分期价值。材料与方法 :2 2例回盲部结肠癌经组织学诊断 ,全部为腺癌 ,CT扫描常规包括肝脏。结果 :CT能够显示肿瘤浸润肠壁的程度以及毗邻器官侵犯的情况。CT肿瘤分期正确为 14例占 6 3 6 % ,估高为 3例占 13 6 % ,估低为 5例占 2 2 7% ;CT对肠周和远处淋巴结的转移显示阳性为 8例 (5 3 3% ) ,假阴性 6例 (4 0 8% ) ,阴性 7例 (4 6 7% ) ,假阳性 1例 (6 6 7% )。结论 :CT对评估病灶局部浸润、远处转移及合理选择手术病例均有一定作用 ,尤其对回盲部疾病的鉴别诊断具有意义。
Purpose : To evaluate the CT staging value of ileocecal colon cancer. Materials and Methods: Twenty-two cases of ileocecal colon cancer were histologically diagnosed. All of them were adenocarcinoma. CT scan routine included liver. RESULTS: CT can show the degree of invasion of the intestinal wall by the tumor and the invasion of adjacent organs. The correct CT tumor stage was 14 cases accounted for 63.6%, the estimated high was 3 cases accounted for 136.0%, and the low estimate was 5 cases accounted for 22.7%; CT showed positive results for the metastasis of perianal and distant lymph nodes in 8 cases (53 cases). 3%), false negative 6 (40% 8%), negative 7 (46.7%), and false positive 1 (6. 7%). Conclusion : CT has a certain effect on the assessment of focal infiltration, distant metastasis and reasonable choice of surgical cases, especially for the differential diagnosis of ileocecal disease.
