摘要
目的 :研究直肠 CT分期与手术中病理所见的关系。方法 :回顾 31例直肠癌术前 CT分期与手术病理分期进行比较 , 和 期的准确率为 85 .7% , a期为 45 .5 % , b 期是 75 % , 期为 10 0 % ,平均 6 7.7%。结果提示 CT能较准确估计直肠的厚度 ,与周围器官的关系及有否远处转移 ,但对直肠周脂肪侵犯及淋巴转移的估计欠佳。结论 :CT对直肠癌术前分期具有一定意义。
Objective:To compare the CT and pathologic stage of rectal carcinoma.Methods: Comparison with CT stage with pathologic stage in 31 patients of rectal carcinoma was carried out retrospectively.Results: In this series the accurate rate of CT stage Ⅰ,Ⅱ,Ⅲ a,Ⅲ b,and stage Ⅳ of rectal carcinoma was 85.7%,45.5%,75%,and 100% respectively, the total accurate rate of CT stage of rectal carcinoma was 67.7%.CT can estimate the thickness of rectum and detect the rectal carcinoma having to invasion to the neighbouring and distant organs,but CT is not effective in evaluating lymph node metastases and invasion of rectal carcinoma to the fatty tissues around the rectum.Conclusion:CT may play an important role in preoperative staging of rectal carcinoma.
