摘　　要：目的探讨急性胰腺炎累及胃肠道的CT表现及其临床意义。方法选择2009年1月1日至6月30日期间131例经影像学检查诊断为急性胰腺炎患者的共计200份影像资料,2位医师回顾性分析图像,重点观察胃肠道受累的CT表现特征,如受累方式、分布特点等。将胃肠道受累与CT严重指数、临床严重程度及转归进行相关性分析。结果共有109例(83.2%)患者出现胃肠道受累的CT征像,主要表现为胃肠道壁增厚伴肠管扩张,胃、十二指肠、空肠和横结肠是常见的受累部位。胃肠道受累与CT严重指数(r=0.689,P=0.000)、临床严重程度(r=0.584,P=0.000)和转归(r=0.346,P=0.000)均呈正相关。结论急性胰腺炎容易出现胃肠道受累,且与疾病的严重程度和预后有关。同其他胰周受累器官一样,胃肠道受累对急性胰腺炎的严重程度评价、预后评估及疗效监测有重要价值。Objective To investigate the CT manifestation and clinical significance of the gastrointestinal tract involvement in acute pancreatitis（AP）.Methods Two hundreds CT scans in 131 patients with acute pancreatitis between Jan.1,2009 and Jun.30,2009 were included into the study.Two radiologists analyzed the images retrospectively,paying attention to the CT features of the gastrointestinal tract involvement,such as the style,distribution,and so on.The correlation between gastrointestinal tract involvement and CT severity index,clinical severity grading,and turnover of acute pancreatitis were studied using a SPSS 14.0 for windows statistics software.ResultsThe CT images in 109（83.2%） patients showed gastrointestinal tract involvement,which distributing mainly stomach,duodenum,jejunum,and transverse colon,and showing mainly the gastrointestinal tract wall thickening and distension.The gastrointestinal tract involvement had positive correlation with CT severity index,clinical severity grading,and turnover of acute pancreatitis（r=0.689,P=0.000;r=0.584,P=0.000;r=0.346,P=0.000）.Conclusions The gastrointestinal tract involvement is common complication in acute pancreatitis and concerns with severity and prognosis of the disease.As other extrapancreatic organs involvement,the gastrointestinal tract involvement has important value for severity assessment,prognosis evaluation,and therapeutic effect monitoring of acute pancreatitis.
