摘　　要：目的:探讨腹部CT检查在结肠肿瘤性肠梗阻患者中的应用价值。方法:选取2015年3月~2016年8月收治的结肠肿瘤性肠梗阻患者108例,并依据诊断方式的不同分为治疗组(n=54)和对照组(n=54),治疗组采用腹部CT探查,对照组采用腹部X线检查。观察并比较两组患者图像清晰度、患者舒适度、梗阻部位情况,计算并比较两组诊断符合率。结果:对照组肠梗阻诊断度、梗阻部位确定度、图像清晰度以及患者舒适度均显著低于治疗组,差异具有统计学意义(P<0.05);CT诊断肠粘连、腹腔感染、肠道肿瘤发生率均显著高于X线诊断,差异具有统计学意义(P<0.05)。结论:腹部CT探查结肠肿瘤性肠梗阻图像清晰,可准确定位发生部位,且诊断度明显高于X线检查,优势突出,对病情的诊断与鉴别具有重要意义,值得临床推广应用。Objective To investigate the value of abdominal computed tomography（CT） examination in the diagnosis of intestinal obstruction resulting from colon cancer. Methods This study was conducted among 108 patients with intestinal obstruction due to colon cancer admitted between March, 2015 and August, 2016. The patients were divided into two groups for examination with abdominal CT（n=54） or X-ray（n=54）. The image quality, patient discomfort, and obstruction site were compared, and the diagnostic accuracy of the two modalities was assessed. Results The diagnostic accuracy of obstruction, the accuracy for determining the obstruction site, image quality and patient comfort were significantly lower in patients with X-ray examination than in those with CT examination（P〈0.05）. CT examination also resulted in significantly higher detection rates of intestinal adhesion, abdominal infection and intestinal tumors than X-ray examination（P〈0.05）. Conclusion For patients with intestinal obstruction due to colon cancer, abdominal CT examination has a greater diagnostic power than X-ray examination and can provide high-quality images to accurately detect the obstruction site.
