【摘要】：目的:探讨不同组织学级别结直肠腺癌CT表现的差异。方法:回顾性分析219例经病理确诊的结直肠腺癌患者临床和CT资料,按组织学分化程度分为高级别结直肠腺癌和低级别结直肠腺癌两组,比较两组患者发病年龄、性别、病变部位、病变肠壁长度及厚度、肠壁增厚形式、强化程度、增强后低密度比例、肠周浸润程度、肠周淋巴结肿大、合并肠梗阻、肝脏和腹膜转移的差异。结果:高级别和低级别结直肠腺癌在病变肠壁增厚形式、肠周浸润程度和肠周淋巴结肿大等方面差异有统计学意义(χ~2=21.571、6.613和34.859,P0.05),在平均发病年龄、性别比例、病变部位、病变肠壁长度及厚度、强化程度、增强后低密度比例、合并肠梗阻肝脏和腹膜转移等方面差异无统计学意义(P0.05)。结论:不同组织学级别的结直肠腺癌CT表现有显著差异。相对低级别结直肠腺癌,高级别结直肠腺癌病变肠壁更易呈环形增厚、肠周浸润程度更重、肠周淋巴结肿大更多。
[Abstract]:Objective: to investigate the difference of CT findings in colorectal carcinoma with different histologic grades. Methods: the clinical and CT data of 219 patients with colorectal carcinoma diagnosed pathologically were analyzed retrospectively. according to the degree of histologic differentiation, they were divided into two groups: high grade colorectal carcinoma and low grade colorectal carcinoma. The age and sex of onset were compared between the two groups. The location of lesion, the length and thickness of intestinal wall, the thickening form of intestinal wall, the degree of enhancement, the ratio of low density after enhancement, the degree of periintestinal infiltration, the enlargement of periintestinal lymph nodes, the difference of intestinal obstruction, liver and peritoneal metastasis. Results: there were significant differences in the thickening of intestinal wall, the degree of periintestinal invasion and peri-intestinal lymph node enlargement between high-grade and low-grade colorectal carcinoma (蠂 ~ 2 鈮，
