多层螺旋CT检查联合生化指标检测在急性胰腺炎诊断中的应用价值

The Value of Multi-slice Spiral CT Combined with Biochemical Index in the Diagnosis of Acute Pancreatitis

为探讨多层螺旋CT(MSCT)检查联合血淀粉酶(SAMY)、尿淀粉酶(UAMY)、胰脂肪酶(LPS)检测在急性胰腺炎诊断中的应用价值,本研究选取80例急性胰腺炎患者作为观察组,另选取同期80例健康者作为对照组。所有患者均给予MSCT平扫和动态增强扫描检查,并检测SAMY、UAMY、LPS水平。观察急性胰腺炎MSCT影像学表现;比较两组SAMY、UAMY、LPS水平;比较不同检查方式诊断急性胰腺炎的灵敏度和特异性。结果显示,急性胰腺炎MSCT影像学表现具有特征性,其中急性水肿型胰腺炎动态增强扫描可见均匀性强化,急性坏死型胰腺炎动态增强扫描可见不均匀强化。观察组SAMY、UAMY、LPS水平均明显高于对照组(P<0.05)。MSCT检查联合SAMY、UAMY、LPS检测诊断急性胰腺炎的灵敏度和特异性均明显高于各单项及多项结合检查(P<0.05)。因此,MSCT检查有助于急性胰腺炎的早期定性诊断,联合生化指标检测可提高诊断急性胰腺炎的灵敏度和特异性,具有重要的临床应用价值。

To investigate the value of multi-slice spiral CT(MSCT)combined with serum amylase(SAMY),urine amylase(UAMY)and lipase(LPS)in the diagnosis of acute pancreatitis.80 patients with acute pancreatitis were selected as the observation group,and 80 healthy persons in the same period were selected as the control group,in this study.All patients were given MSCT plain scan and dynamic enhanced scan,and the levels of SAMY,UAMY and LPS were detected.To observe the MSCT imaging of acute pancreatitis.To compare the levels of SAMY,UAMY and LPS in the two groups.To compare the sensitivity and specificity of different examination methods in the diagnosis of acute pancreatitis.The results showed that the MSCT imaging features of acute pancreatitis are characteristic,in which the dynamic enhanced scan of acute edematous pancreatitis shows homogeneous enhancement,and the dynamic enhanced scan of acute necrotic pancreatitis shows uneven enhancement.The levels of SAMY,UAMY and LPS in the observation group were significantly higher than those in the control group(P<0.05).The sensitivity and specificity of MSCT combined with SAMY,UAMY and LPS in the diagnosis of acute pancreatitis were significantly higher than those of single and multiple combined examinations(P<0.05).Therefore,MSCT is helpful for the early qualitative diagnosis of acute pancreatitis,and combined with biochemical index can improve the sensitivity and specificity in the diagnosis of acute pancreatitis,which has important clinical application value.
