摘要 目的针对急诊收治的一例疑似小肠梗阻(SBO)患者,检索当前最佳证据,为临床合理诊断提供依据。方法计算机检索MEDLINE/PubMed (1978~2006.4)、SUMsearch(1978~2006.4)、CNKI(1978~2006.4),查找有关计算机体层摄影术(CT)诊断小肠梗阻的系统评价、横断面研究等,并对所获证据进行评价。结果临床证据表明,与参考标准小肠造影及外科手术诊断相比较,CT诊断小肠梗阻的敏感度和特异度均较高,并能在早期明确梗阻的类型及病因,提高临床医师正确处理小肠梗阻的能力。据此临床证据,结合患者意愿,对患者进行CT检查,CT结果提示绞窄性小肠梗阻,需立即进行手术治疗。结论CT是诊断小肠梗阻敏感性及特异性均较高的影像学检查方法。 Objective We sought a good understanding of the current role of computed tomography (CT) in the diagnosis of small bowel obstruction (SBO).Methods We looked for the best evidence on computed tomography for diagnosing small bowel obstruction by searching MEDLINE/ PubMed (1978-April, 2006), SUMsearch (1978-April, 2006), CNKI (1978-April, 2006) and critically appraised the evidence. Results There was powerful evidence supporting the efficacy of computed tomography in the diagnosis of small bowel obstruction. Given the current evidence together with our clinical experience and considering the patient and his family members, values and preferences, computed tomography was done. We confirmed the bowel obstruction, which diagnosis of strangulating small needed immediate operation. Conclusions Computed tomography is a very useful tool for the diagnosis of small bowel obstruction with high sensibility and specificity.
