多层螺旋CT对结肠癌性肠梗阻的诊断价值

The diagnostic value of multi-slice spiral CT to carcinomatous intestinal obstruction of colon

【摘要】目的探讨多层螺旋CT（MSCT）在结肠癌性肠梗阻诊断中的临床价值。方法分析40例MSCT诊断为结肠癌性肠梗阻患者的临床资料及MSCT检查资料。结果40例MSCT诊断结肠癌性肠梗阻患者中，完全性肠梗阻17例，不完全性肠梗阻23例，经手术病理证实39例为结肠癌性肠梗阻，1例证实为肠多发息肉所致套叠性肠梗阻，梗阻原因定性准确率为97．5％（39／40），肠梗阻诊断准确率为100．0％（40／40）；梗阻部位：升结肠14例，横结肠4例，结肠脾曲2例，降结肠6例，乙状结肠12例，横结肠与升结肠复合病变1例，结肠及小肠多发病变1例，MSCT对病变部位诊断准确率为100．0％（40／40）。结论MSCT对结肠癌性肠梗阻在确定梗阻存在、梗阻部位、梗阻原因方面具有明显优势，能为临床治疗提供重要诊断价值。

Objective To explore the clinical value of multi-slice spiral CT （MSCT） to carcinomatous intestinal obstruction of colon. Methods The clinical and MSCT data of 40 patients with carcinomatous intestinal obstruction of colon diagnosed by MSCT were analyzed. Results In the 40 cases,complete intestinal obstruction were in 17 cases,incomplete intestinal obstruction in 23 cases,39 cases were carcinomatous intestinal obstruction of colon confirmed by surgery and pathology,and 1 case was intussusception intestinal obstruction by multiple polyps. The MSCT qualitative analysis of obstruction reason was 97.5% （39/40）,the MSCT diagnostic accuracy of intestinal obstruction was 100.0% （40/40）. The obstruction site was at ascending colon showed in 14 cases,transverse colon in 4 cases,splenic flexure of colon in 2 cases, descending colon in 6 cases, sigmoid colon in 12 cases, both ascending colon and transverse colon in 1 case,colon and small intestine in 1 case. The obstruction site accuracy rate of MSCT was 100.0% （40/40）. Conclusion MSCT has obvious advantages in obstruction existing, obstruction site, obstruction reason to carcinomatous intestinal obstruction of colon, it can offer reliable examination data to clinic.
