摘　　要：目的旨在探讨多层螺旋CT(MSCT)及超声检查对非外伤性急腹症诊断效能。方法将2017年1月至2017年12月于我院就诊治疗的85例非外伤性急腹症患者作为研究对象,对比两种检查对非外伤性急腹症的诊断准确率。结果MSCT对非外伤性急腹症诊断符合率为98.82%(84/85),明显高于经腹壁超声对非外伤性急腹症诊断符合率为91.76%(78/85)(χ^2=4.722,P=0.030);急性胆囊炎MSCT图像可见胆囊周围组织水肿,急性胆囊炎在Murphy's征中,超声征象主要为胆囊壁增厚为主;急性胰腺炎MSCT图像提示胰腺肿胀、密度不均,超声显示胰腺呈现弥漫性肿大;机械性肠梗阻MSCT图像为梗阻近侧肠管以及梗阻远侧不扩张肠管,超声检查提示肠管扩张且多合并肠腔积液;MSCT图像、超声检查均可有效显示结石、阑尾炎典型影像学表现。结论MSCT及超声检查均能有效显示不同非外伤性急腹症图像特征,但MSCT对非外伤性急腹症诊断符合率优于超声检查。Objective To investigate the diagnostic efficacy of multi-slice spiral CT (MSCT) and ultrasonography in non-traumatic acute abdomen.Methods 85 patients with non-traumatic acute abdomen who were treated in our hospital from January 2017 to December 2017 were selected as the research objects,and the diagnostic accuracy of the two examinations for non-traumatic acute abdomen was compared.Results The coincidence rate of MSCT in the diagnosis of non-traumatic acute abdomen was 98.82%(84/85),which was significantly higher than that of transabdominal ultrasound in the diagnosis of non-traumatic acute abdomen 91.76%(78/85)(χ^2=4.722,P=0.030).MSCT images of acute cholecystitis showed edema around the gallbladder.In Murphy's sign of acute cholecystitis,the main ultrasonographic signs were gallbladder wall thickening, MSCT images of acute pancreatitis showed pancreatic swelling and uneven density. Ultrasound showed diffuse pancreatic enlargement.The MSCT images of mechanical intestinal obstruction were the proximal intestinal obstruction and the distal non-dilated intestinal obstruction.Ultrasound examination showed dilatation of intestine and intestinal effusion.MSCT and Ultrasound can effectively display the typical imaging manifestations of calculi and appendicitis.Conclusion MSCT and ultrasound can effectively display the image features of different non-traumatic acute abdomen,but the coincidence rate of MSCT in diagnosis of non-traumatic acute abdomen is better than that of ultrasound.
