急性胰腺炎早期CT检查的价值

目的:探讨急性胰腺炎的CT征象、分级与临床分型、预后的关系以及CT对急性胰腺炎早期诊断的价值。方法:对56例手术病理或复查证实急性胰腺炎的CT资料进行回顾性分析,并按CT分为A、B、C、D、E五级的各组病例分别与血尿淀粉酶进行分析。结果:CT表现胰腺肿胀49例(87.5%),胰腺渗液38例(67.8%),胰腺坏死18例(33%),假性囊肿形成11例(19.64%),合并感染或脓肿形成8例(14.28%)。血尿淀粉酶与CT比较:A级5例(8.92%)血尿淀粉酶轻度升高,B级13例(23.21%)中度升高,C级11例(19.64%)显著升高,D级8例(14.28%)血尿淀粉酶趋向下降,E级19例(33.92%)显著下降。结论:CT对急性胰腺炎的早期诊断有非常重要价值,应作为诊断急性胰腺炎的首选方法。

Diagnostic value of CT in the early stage of acute panc reatitis

Objective:To evaluate the relatio ns hip among CT findings,gradings,clinical types and prognosis of acute pan-cre atitis,judge the CT value in the diagnosis of acute pancreatitis.Methods:Fif ty-six cases of acute pancreatitis confirmed by operation,pathology and CT re examination were reviewed.Five grades divided by CT findings were analysed and compared to the serum and urine amylase respectively.Results:According to CT f indings,swelling in49cases (87.5%),exulation in38cases(67.8% ),necrosis in18cases(33%),pseudocysts formation in11cases(19.6 4%),eight cases were complicated with infection or abscess(14.28%) .Compared serum and urine amylase to CT findings:the serum and urine amylase i ncreased slightly in grade A(8.92%),moderately in grade B(23.21% ),markedly in grade C(19.64%),but tended to decrease in grade D(1 4.28%),and de-creased dramatically in grade E (33.92%).Conclusi on:CT play an important role in early stage of acute pancreatitis,it should be the first selective method in diagnosing acute pancreatitis.
