摘要
目的探讨螺旋CT在老年急腹症病因诊断中的价值。方法回顾性分析2008年2月—2011年3月老年急腹症患者86例。采用GE公司16排螺旋CT对所有患者进行腹部平扫。结果急腹症患者86例中,CT结果与临床诊治相符80例,诊断准确率93.0%(80/86),其中真阳性60例,真阴性20例;与临床诊治不符6例,其中假阳性4例,假阴性2例。2例老年阑尾炎穿孔形成阑尾周围脓肿继发肠管粘连诊断为单纯性肠梗阻,1例腹腔急性化脓感染诊断为消化道穿孔,1例回盲部肿物诊断为阑尾周围脓肿,2例肠系膜动脉闭塞症未能行增强扫描而误诊。CT诊断的敏感度为96.8%(60/62),特异度为83.3%(20/24)。结论螺旋CT是一种有效、简便、快速的影像学诊断方法,能较为准确的显示疾病的部位、范围及周围组织的受损情况,在老年急腹症诊断中具有重要的价值,值得临床推广应用。
Objective To evaluate the spiral CT in the diagnosis of acute abdomen in the elderly. Methods A total of 86 patients underwent spiral CT for the diagnosis of acute abdomen from February 2009 to March 2011. The clinical data and image data were analyzed. Results Eighty out of 86 （93.0%） cases diagnosed by spiral CT accorded with clinical diagnosis, but 6 cases were non - accordant. CT showed 60 true positive ,20 true negative ,4 false positive ,2 false negative ,which yielded a sensitivity of 96.8% （60/62）and a specificity of 83.3% （20/24）. Two cases of the periappendicural abscess from appendicular perforation with the secondary intestines adhesion in the elderly were misdiagnosed as the intestinal obstruction. A case of acute suppurative infection in abdominal cavity of the elderly was misdiagnosed as the abnormal perforated. A case of the ileocecus mass was misdiagnosed as the periappendicural abscess. Two cases of the mesenterie artery obliteration were misdiagnosed because the enhanced MR image was not acquired. Conclusion Spiral CT is a rapid and simple imaging technique with higher sensitivity, specificity and accuracy. Spiral CT is an effective method in the diagnosis of acute abdomen in the elderly.
