目的 　針對急診收治的一例疑似小腸梗阻（SBO）患者，檢索當(dāng)前最佳證據(jù)，為臨床合理診斷提供依據(jù)。
方法 　計算機檢索MEDLINE/PubMed（1978~2006.4）、SUMsearch（1978~2006.4）、CNKI（1978~2006.4），查找有關(guān)計算機體層攝影術(shù)（CT）診斷小腸梗阻的系統(tǒng)評價、橫斷面研究等，并對所獲證據(jù)進行評價。
結(jié)果 　臨床證據(jù)表明，與參考標(biāo)準(zhǔn)小腸造影及外科手術(shù)診斷相比較，CT診斷小腸梗阻的敏感度和特異度均較高，并能在早期明確梗阻的類型及病因，提高臨床醫(yī)師正確處理小腸梗阻的能力。據(jù)此臨床證據(jù)，結(jié)合患者意愿，對患者進行CT檢查，CT結(jié)果提示絞窄性小腸梗阻，需立即進行手術(shù)治療。
結(jié)論 　CT是診斷小腸梗阻敏感性及特異性均較高的影像學(xué)檢查方法。
