多层螺旋CT在诊断小肠梗阻中的应用研究

摘要

目的:研究多层螺旋CT在诊断小肠梗阻中的应用价值.方法:选取我院2012年1月至2016年12月88例小肠梗阻患者为研究对象,所有患者均经手术证实,采用多层螺旋CT检查,以手术证实结果为金标准,计算多层螺旋CT诊断小肠梗阻部位、程度、病因的准确率.结果:CT正确检出小肠梗阻部位80例,准确率为90.9％,包括6例十二指肠梗阻,17例空肠梗阻,57例回肠梗阻.CT正确检出完全性小肠梗阻60例,不完全小肠梗阻21例,CT对小肠梗阻程度诊断准确率92.1％.CT正确检出小肠梗阻病因79例,准确率为89.8％,包括肠粘连39例,炎症14例,肿瘤11例,腹外疝5例,肠扭转4例,外伤性小肠梗阻2例,血运性小肠梗阻2例,先天性小肠梗阻2例.结论:多层螺旋CT可以准确诊断小肠梗阻部位、程度、病因,对手术治疗具有重要指导作用.%Objective:To study the application value of multi-slice spiral CT in the diagnosis of small intestinal obstruction. Methods:88 cases of patients with small intestinal obstruction confirmed by surgery in our hospital from January 2012 to December 2016 were selected for the study and treated with multi-slice spi-ral CT examination. The accuracy rates of the site, degree and etiology of small intestinal obstruction were cal-culated by the multi-slice spiral CT diagnosis. Results: There were 80 cases of small intestinal obstruction correctly detected by CT with the accuracy rate of 90.9％, including 6 cases of duodenal obstruction, 17 cases of jejunum obstruction and 57 cases of ileal obstruction. There were 60 cases of complete small intestinal ob-struction and 21 cases of incomplete small intestinal obstruction correctly detected by CT with the accuracy rate of 92.1％. And there were 79 cases of small intestine obstruction detected with etiology by CT with the accura-cy rate of 89.8％, including 39 cases of intestinal adhesions, 14 cases of inflammation, 11 cases of tumors, 5 cases of external hernia, 4 cases of intestinal torsion, 2 cases of traumatic small intestinal obstruction, 2 cases of blood-borne small intestinal obstruction and 2 cases of congenital small intestinal obstruction. Conclusion:Multi-slice spiral CT can accurately diagnose the site, degree, etiology of small intestinal obstruction, and have an important guiding role in surgical treatment.
