目的 探讨经大肠充盈超声检查在诊断炎症性肠病及大肠癌中的的应用价值.方法 对临床诊断明确的炎症性肠病即Crohn病(CD) 24例、溃疡性结肠炎(UC) 31例,与大肠癌30例对比观察大肠超声图像特点并与结肠镜所见情况比较.结果 经超声检查Crohn病和大肠癌的肠壁增厚例数明显高于溃疡性结肠炎,大肠癌肠系膜淋巴结肿大的比例较高,在彩超多普勒血流频谱显示大肠癌和炎症性肠病的收缩期峰值流速及舒张末期最低流速的差异方面,均有统计学意义.结论 大肠充盈超声检查简便易行,在声像图上炎症性肠病和大肠癌的表现有特点,对病变的部位、范围、性质的判断具有较高的准确性,与肠镜检查结合可明显提高炎症性肠病和大肠癌的检出率和诊断率.%Objective To investigate the vale of bowel contrast ultrasound in the diagnosis of colorectal cancer and inflammatory bowel disease. Methods 24 cases of Crohn's disease (CD) , 31 cases of ulcerative colitis (UC) , 30 cases of colorectal cancer with known clinical diagnosis were compared by ultrasound images and findings of colonosco-py. Results By ultrasound examination, bowel wall thickening of Crohn's disease and colorectal cancer patients was significantly higher than that of ulcerative colitis, colorectal cancer had a higher proportion of mesenteric lymph nodes, the systolic and diastolic peak flow velocity variations of colorectal cancer and inflammatory bowel disease were statistically significant. Conclusions On the sonogram Crohn's disease, ulcerative colitis and colorectal cancer had their own performance characteristics. It is simple,accurate and helpfult to determine the location,extent and nature of the lesion, combining with colonoscopy ,it can significantly improve the detection rate of colorectal cancer and Intestine inflammatory Disease.
