超声检查对诊断急性胰腺炎的临床价值

Value of ultrasound on diagnosis of acute pancreatitis

目的：探讨超声检查对诊断急性胰腺炎的临床价值。方法选取驻马店市中心医院自2012年1月至2013年6月收治的104例急性胰腺炎患者为研究对象，所有患者均行腹部超声及 CT平扫检查，比较两者对诊断急性胰腺炎的临床价值。结果超声对轻型胰腺炎的诊断准确率低于 CT（72.8% vs 84.8%，χ2=5.968，P﹤0.05），但对于胰周或腹腔积液的准确率明显高于 CT（45.8% vs 28.6%，χ2=6.748，P ﹤0.05）；超声对于重型胰腺炎、胰腺增大和胰腺实质回声改变的诊断率稍低于 CT，但二者间差异无统计学意义（ P均﹥0.05）。结论超声检查诊断急性胰腺炎具有较高的准确率，尤其是对于胰周渗出和腹腔积液的检出率高于CT，值得推广应用。

Objective To investigate the clinical value of ultrasound on diagnosis of acute pan-creatitis. Methods The data of 104 patients with acute pancreatitis admitted in our hospital from January 2012 to June 2013 were studied. All patients received abdominal ultrasound and CT scan,and the clinical values on diagnosing acute pancreatitis were compared. Results The diagnostic accuracy rate of ultrasound for light pancreatitis was lower than that of CT（ 72. 8% vs 84. 8%,χ2 =5. 968 ,P ﹤0. 05 ）,while the diagnostic accuracy rates for peripancreatic or abdominal cavity effusion were obviously higher than that of CT（45. 8% vs 28. 6%,χ2 =6. 748,P﹤0. 05）. The diagnostic accuracy rates of ultra-sound for severe pancreatitis,pancreas and pancreatic parenchyma echo change were lower than that of CT,but there was no statistical differences（ Pall﹥0. 05）. Conclusions The diagnostic accuracy rate of ultrasound for acute pancreatitis is high,especially for peripancreatic oozy and peritoneal effasion,and it is worth of popularization and application.
