摘　　要：目的:应用多排螺旋CT鉴别诊断直径大于1cm升结肠腺瘤、腺瘤癌变,以提高结肠腺瘤术前分期的诊断准确性,为临床制定治疗方案提供一定依据。方法:搜集2010年1月至2011年12月间在我院进行多排螺旋CT增强检查发现升结肠肿瘤并手术治疗的29例患者,分析肿瘤大小、肿瘤密度及强化程度、周围脂肪间隙等影像学特征与病理诊断结果相对照。结果:29例患者中升结肠腺瘤11例,腺瘤癌变18例,包括管状腺癌11例、黏液腺癌7例;腺瘤及腺瘤癌变在病灶大小、强化程度、周围脂肪间隙方面有显著统计学差异(P<0.05)。结论:多排螺旋CT提供了较多的影像信息,包括肿瘤大小,平扫密度、强化程度、周围脂肪间隙等方面,有助于鉴别诊断大于1cm的升结肠腺瘤和腺瘤癌变,在升结肠腺瘤和腺瘤癌变诊断中具有重要价值。Purpose：To evaluate the value of multi-slice spiral computed tomography （MDCT） in differential diagnosis of ascending colon adenoma and cancerous adenoma with diameter greater than 1cm,and to improve the staging of preoperative colorectal adenoma and cancerous adenoma.Methods：Twentynine patients,who have undergone pre-contrast and post-contrast MDCT and were first considered colon adenoma canceration from January 2010 to December 2011,were enrolled.All patients were confirmed by clinical pathology and immunohistochemistry in our hospital.Tumor size,tumor density and degree of enhancement,surrounded fat space were analyzed.Results：All twenty-nine patients were with single mass located in ascending colon,including eleven adenomas,eleven adenoma cancerations and seven mucinous adenocarcinomas.The differences of tumor size,pre-contrast density,enhanced density and surrounded fat space among adenoma and adenoma canceration were with statistical significant （P＜0.05）.Conclusion：Multi-slice spiral computed tomography techniques can provide useful information about the tumor size,pre-contrast density,degree of enhancement,the condition of fat clearance about the ascending colon tumor,which is helpful to differentiate the adenoma,adenoma canceration and mucinous adenocarcinoma.
