[摘要] 目的 探討螺旋CT在急性腸梗阻診斷中的應用價值。方法 隨機選取2010年1月—2015年12月該院收治的40例急性腸梗阻患者為研究對象,全部患者均現以螺旋CT進行平掃和增強掃描,對比手術病例結果評估螺旋CT診斷急性腸梗阻的準確性和敏感性。結果 螺旋CT診斷結果顯示40例患者均為腸梗阻,診斷敏感性100%。螺旋CT對梗阻病因的診斷準確率為92.5%(37/40),螺旋CT對梗阻部位的診斷準確率為97.5%(39/40)。其中,對結腸梗阻部位判斷準確率100%(17/17),對小腸梗阻部位判斷準確率95.65%(22/23),比較差異無統計學意義(P>0.05)。 結論 以螺旋CT診斷急性腸梗阻敏感性高,既可用于確定梗阻部位,又能較為準確的判斷病因,可為臨床有效治療急性腸梗阻提供可靠依據,具備良好應用價值,值得推廣使用。

[Abstract] Objective To explore the value of spiral CT in the diagnosis of acute intestinal obstruction. Methods Random selection January 2010 to December 2015 in our hospital from 40cases of acute intestinal obstruction patients as the research object. All patients are now using spiral CT flat scanning and enhancement scanning and contrast cases evaluation results spiral CT in the diagnosis of acute intestinal obstruction of sensitivity and accuracy. Results Spiral CT diagnosis showed that 40cases were intestinal obstruction, the diagnostic sensitivity was 100%. The diagnostic accuracy of spiral CT in the cause of obstruction was 92.5%(37/40), and the diagnostic accuracy was 97.5%(39/40). Among them, the accuracy rate of 100% (17/17) on the site of obstruction of colon was 95.65% (22/23), and the difference was not statistically significant (P > 0.05).Conclusion Spiral CT in diagnosis of acute intestinal obstruction, high sensitivity, can used to determine the site of obstruction, and can be more accurate to determine the reason for the clinical treatment of acute intestinal obstruction to provide reliable basis and have good application value, is worthy to be popularized.

急性腸梗阻即腸道機械性堵塞,屬臨床常見急腹癥,具有發病率高、病情進展迅速的特點,常導致患者死亡,有數據統計,其致死率最高可達15%[1],嚴重威脅患者生命。早期病因診斷、準確對梗阻進行定位和定性并科學把握治療時機是臨床成功救治急性腸梗阻患者的關鍵。既往,臨床多采用X線立位腹平片檢查,此法雖具備診斷價值,也能幫助臨床警惕腸絞窄,但存在一定漏診率,梗阻點的確定也并不十分明確,故無法很好的指導臨床進一步治療。該院近年來以螺旋CT診斷急性腸梗阻收效滿意,該文現以2010年1月—2015年12月該院收治的40例急性腸梗阻患者為例進行分析和探討,現報道如下。……
