彩色多普勒超声在诊断急性胰腺炎中的价值

目的探讨彩色多普勒超声诊断急性胰腺炎的价值。方法回顾性分析55例急性胰腺炎患者病例资料，均行超声和CT检查。同时选取无胰腺炎的腹痛患者40例为对照组。结果急性胰腺炎患者的彩色多普勒超声以胰腺体积增大和内部回声变化为主要表现。55例中急性水肿型胰腺炎36例，急性坏死型胰腺炎19例。彩色多普勒超声检出率为92．7％，CT检出率为94．5％，两组比较无统计学意义（X2=0．1526，P=0．6961〉0．05）。急性胰腺炎患者十二指肠下动脉血流最大速度明显低于对照组的血流最大速度，差异具有统计学意义（t=2．0191．P〈0．05）。结论彩色多普勒超声诊断急性胰腺炎具有准确率高、无创、经济的优点，具有重要临床诊断价值。

he value of color Doppler ultrasound on patients with acute pancreatitis

Objective To study the value of color Doppler ultrasound on patients with acute pancreatitis. Methods Fifty-five patients with acute pancreatitis were enrolled into the observation group.They were detected through color Doppler ultrasound and CT. Forty patients who had bellyache without pancreatitis were enrolled into the control group. Results The main performances through color Doppler ultrasound were the pancreatitis volume increases and changes in the internal echo.There were thirty-six patients with acute edematous pancreatitis and nineteen patients with acute necrotizing pancreatitis. Color Doppler ultrasound detection rate was 92.7%, CT detection rate of 94.5%,no significant difference （X2=0.1526,P = 0.6961 〉 0.05）. The maximum speed of the arterial blood flow in the duodenum of patients with acute pancreatitis maximum speed of blood flow was significantly lower than the control group, a statistically sig- nificant difference （t = 2.0191 ,P 〈 0.05）. Conclusion Color Doppler ultrasound diagnosis for acute pancreatitis were with high accuracy, non-invasive, the economic advantages of an important clinical diagnostic value.
