腹部CT扫描诊断急性胰腺炎及其并发症的临床效果观察

Clinical Effect of Abdominal CT Scan in Diagnosis of Acute Pancreatitis and Its Complications

目的:观察腹部CT扫描诊断急性胰腺炎及其并发症的临床效果。方法:选取2019年1月~2020年6月本院收治的176例疑似急性胰腺炎合并并发症患者进行研究,分别对患者实施腹部CT扫描及B超扫描,对比分析不同诊断方式对急性胰腺炎及其并发症的诊断效果。结果:与病理诊断结果对比,腹部CT诊断急性胰腺炎的灵敏度为98.13%(157/160),特异度为62.50%(10/16),B超诊断急性胰腺炎灵敏度为71.88%(115/160),特异度为25.00%(4/16),腹部CT诊断急性胰腺炎的灵敏度及特异度均高于B超诊断结果(χ^(2)=3.989、4.571,P=0.046、0.033)。腹部CT检出胰腺出血、蜂窝织炎、胰性腹水、胰腺假性囊肿、胃底静脉曲张比例均高于对照组(P<0.05)。腹部CT扫描成片良好比例90.91%相比对照组的71.02%更高(P<0.05)。结论:腹部CT诊断急性胰腺炎的灵敏度及特异度均较B超更高,且可有效提升诊断准确性。

Objective:To observe the clinical effect of abdominal CT scan in the diagnosis of acute pancreatitis and its complications.Methods:176 patients with acute pancreatitis complicated with complications admitted in our hospital from January 2019 to June 2020 were selected for the study.Abdominal CT scanning and B-ultrasound scanning were carried out respectively,and the diagnostic effects of different diagnostic methods on acute pancreatitis and its complications were compared and analyzed.Results:Compared with pathological diagnosis,the sensitivity and specificity of abdominal CT in the diagnosis of acute pancreatitis were 98.13%(157/160)and 62.50%(10/16),respectively.The sensitivity and specificity of B-ultrasound in the diagnosis of acute pancreatitis were 71.88%(115/160)and 25.00%(4/16),respectively.The sensitivity and specificity of abdominal CT in the diagnosis of acute pancreatitis were higher than those of B-ultrasound(χ^(2)=3.989,4.571,P=0.046,0.033).The proportion of pancreatic hemorrhage,cellulitis,pancreatic ascites,pancreatic pseudocyst and gastric varices detected by abdominal CT were higher than those in the control group(P<0.05).The good rate of abdominal CT scanning was 90.91%,which was higher than 71.02%of the control group(P<0.05).Conclusion:The sensitivity and specificity of abdominal CT in the diagnosis of acute pancreatitis are higher than that of B-ultrasound,which can effectively improve the diagnostic accuracy.
