增强CT与彩色多普勒超声在诊断急性胰腺炎中的价值研究

Study on the value of enhanced CT and color Doppler ultrasound for diagnosis of acute pancreatitis

目的分析彩色多普勒超声与增强CT在诊断急性胰腺炎中的诊断价值。方法分析我院自2011年1月～2013年1月收治的急性胰腺炎患者102例，比较102例患者增强CT表现及超声表现，胰腺炎检出率。结果（1）在胰管扩张、胆总管结石方面比较，超声检出率显著高于CT，差异具有统计学意义（P〈0．05）；胰腺局限性增大、胰腺内小灶液区，CT检出率显著高于超声，差异具有统计学意义（P〈0．05）。（2）超声与CT检出轻型急性胰腺炎检出率分别为67．6％与83．8％，差异具有统计学意义（P〈0．05）；重型急性胰腺炎超声与CT检出率分别为92．8％与96．4％，差异无统计学意义（P〉0．05）。结论CT与彩色超声在诊断急性胰腺炎中均具有重要价值，在临床应用中可以将二者联合应用，即可以相互弥补缺陷，又可以发挥各自优势，提高急性胰腺炎的临床要检出率。

Objective To analyze the diagnostic value of color Doppler ultrasound and enhanced CT for diagnosis of acute pancreatitis. Methods 102 cases of acute pancreatitis admitted and treated in our hospital from Jan 2011 to Jan 2013 were analyzed. The manifestations and detection rates of pancreatitis in the 102 cases scanned by enhanced CT and ultrasound were compared. Results （1）Ultrasound had higher detection rate of pancreatic duct dilatation and common bile duct stone than CT, with statistical significanee（P 〈 0.05）; CT had higher detection rate of local enlarged pancreas and pancreatic fluid within the small focal area than ultrasound, with statistical significance（P 〈 0.05）. （2）The detection rate of mild acute pancreatitis was 67.6% for ultrasound and 83.8% for CT, with statistical signifieance（P 〈 0.05）. The detection rate of severe acute pancreatitis was 92.8% for ultrasound and 96.4% for CT, without statistical significance（P 0.05）. Conclusion Both CT and color ultrasound have important value for diagnosis of acute pancreatitis. CT and color ultrasound should be combined in clinical practice to make up the defects of each other and give full play to the advantages of each other so as to improve the clinical detection rate of acute pancreatitis.
