摘要 目的探讨急性胰腺炎患者最佳CT检查时间。方法本研究选择2008年1月~2010年3月对确诊的172例急性胰腺炎的患者,随机分为3组,分别在发病≤12 h、12~24 h、48~72 h行CT检查。为观察病情变化,在发病≤12 h行CT检查的患者在72~120 h期间行第二次CT检查,分析不同时间段的CT检出率和Balthazar分级情况,以确定最佳CT检查时间。结果随着时间的推移,CT检查发现胰腺炎的阳性率逐渐增高,88.7%的患者12~24 h CT检查阳性率明显高于在发病12 h之内行CT检查的阳性率,差异显著(P〈0.05),但与在发病48~72 h和72~120 h行CT相比,无显著差异(P〉0.05)。按照Balthazar CT分级标准,对确诊的胰腺炎患者不同时间段分级进行研究发现:随着时间的延长,患者D级、E级检出率逐渐增多,48~72 h D级、E级检出率明显高于12 h之内和12~24 h之间检出率(P〈0.05);但与72~120 h相比,无显著性差异(P〉0.05)。结论对于疑诊胰腺炎的患者在发病12~24 h行CT检查可较早检测到胰腺炎的变化;在48~72 h行CT检查可较早检测到胰腺炎的严重程度。 Objective To discuss the optimal opportunity of CT examination in patients with AP. Methods CT examination in patients with AP was executed witin 12 hours,from 12 to 24 hours,from 24 to 72 hours,from 72 to 120 hours.The positive value of CT was analyzed in different time span. Results The positive rate of CT examination from 12 to 24 hours in patients with AP was significantly higher than that witin 12 hours(P0.05).There was no difference between from 12 to 24 hours span and from 24 to 120 hours span(P0.05).According to Balthazar CT grade standard,the positive rate of D、E grade SAP from 48 to 72 hours span was significantly higher than that witin 12 hours and from 12 to 24 hours span(P0.05);there was no difference between from 24 to 72 hours span and from 72 to 120 hours span(P0.05). Conclusion CT can diagnose pancreatic inflammatory and formal change as early as possible from 12 to 24 hours;CT can differentiate SAP as early as possible from 48 to 72 hours.
