摘要：

目的 探讨直肠内充气CT在直肠癌诊断和临床分期中的意义。 方法 回顾性分析2007年5月至2009年7月胶南市经济技术开发区医院54例经手术病理证实直肠癌病人的直肠内充气CT表现，评价直肠内充气CT在直肠癌诊断和临床分期中的价值。 结果 直肠内充气CT病人直肠及乙状结肠充分扩张，包绕直肠周围脂肪密度结构，与密度相对较高的肠壁及极低密度肠腔对比清晰。直肠内充气CT对直肠癌TNM分期总的准确率为85.2%（46/54），T 分期准确率为 90.7%（49/54），N 分期准确率为 87.0% （47/54），M 分期准确率为98.1%（53/54）。结论 直肠内充气CT能够清晰显示直肠癌的大小，形态，浸润深度，淋巴结转移情况，与周围器官关系及远处转移情况，获得清晰的直肠系膜影像学特征。直肠内充气CT与TNM病理分期有较高的一致性，是直肠癌术前诊断与临床分期的重要方法。

Abstract:

Significance of inflatable rectal CT in the diagnosis and clinical staging of rectal cancer LI Wei, LIU Ke-sheng，CUI Gen. Department of General Surgery, Jiaonan Economic and Technological Development Zone Hospital,Jiaonan 266400,China Corresponding author: LI Wei， E-mail: Liwei_750518@163.com Abstract Objective To evaluate the significance of inflatable rectal CT in the diagnosis and clinical staging of rectal cancer．Methods Inflatable rectal CT of 54 cases of rectal cancer confirmed by surgery pathology between May 207 and July 2009 at Jiaonan Economic and Technological Development Zone Hospital were investigated retrospectively. It evaluated the significance of inflatable rectal CT in the diagnosis and clinical staging of rectal cancer．Results Full expansion of the rectum and sigmoid colon, rectum wrapping around the fat density of the structure of the intestinal wall and the relatively high density and very low density contrast mesocaval were showed clearly in patients with the inflatable rectal CT. The overall accuracy rate of rectal cancer TNM staging was 85.2%（46/54）. The accuracy of T, N and M was 90.7%(49/54）, 87.0% (47/54)and 98.1%(53/54) respectively. Conclusion Inflatable rectal CT can show the size, shape, depth of invasion, lymph node metastasis, the relationship with the surrounding organs and distant metastasis clearly. Imaging features of the mesorectum were clear. Inflatable rectal CT had a higher consistency with TNM staging.It was an important method for the preoperative diagnosis and clinical staging of rectal cancer.
