急性胰腺炎的CT诊断评价

Evaluation of CT diagnosis of acute pancreatitis

目的探讨急性胰腺炎的CT诊断价值。方法对31例临床拟诊急性胰腺炎病人进行CT扫查,取层厚5mm,平扫+增强扫描,重点观察胰腺大小、形态、胰周肾旁筋膜、间隙、胸腹腔情况。结果 CT诊断急性水肿型胰腺炎25例,急性出血坏死型胰腺炎6例,诊断准确率100%。胰腺弥漫性增大或局限性增大20例,胰腺密度改变22例,胰腺周围液体聚集7例,胰腺内坏死、出血4例;肾周筋膜增厚16例;并发蜂窝组织炎5例、假性囊肿3例、脓肿2例、合并胸腔积液7例。结论 CT检查对急性胰腺炎不仅可定性诊断,同时还可显示胰腺内外情况及有无并发症发生,具有重要的临床价值。

Objective To explore the value of CT in the diagnosis for urgent pancreatitis.Methods 31 patients with acute pancreatitis were treated with CT with 5mm thickness,including plain and contrast enhanced scan.Pancreas size,shape,peripancreatic perirenal fascia,space and chest cavity were observed.Results By CT,25 patients diagnosed with acute edematous pancreatitis and 6 patients diagnosed with acute hemorrhagic necrotizing pancreatitis（CT diagnostic accuracy is 100%）.20 cases were showed diffuse increased as the pancreas or limitations increase.22 patients showed with changes in the density of the pancreas.7 cases showed with peri-pancreatic fluid collection.4 patients showed with pancreatic necrosis,hemorrhage.16 cases showed with perirenal fascial thickening.5 cases were complicated with cellulitis,3 cases with pseudocyst,2 cases with abscess and 7 cases with pleural effusion.Conclusion CT examination in diagnosis of acute pancreatitis can show the situation inside and outside the pancreas and the presence of complications.
