Analysis Of Testing Bile Duct Lesions Of Hepatic Artery Blood Flow

Objective:Though compareing with ERCP and pathological result, evaluate the value of color Doppler ultrasound assessment of hepatic hemodynamics test in differential diagnosis of lower bile duct lesions.Methods:Select 85 cases suspicious biliary tract diseases with Varying degrees of bile duct diameter widened. Including gallbladder disease with cholangitis lesions group (GDCL)38, cholecystectomy cholangitis lesions group(CCL)28, bile duct tumor suspicious group(BDTS) 19. 59 receive ERCP examination and were confirmed, including 40 cases of inflammatory lesions and 19 cases of bile duct tumor lesions. Focus on extrahepatic bile duct diameter, wall thickness, lumen transparent sound, hepatic artery peak flow velocity(PSV) and resistance index(RI). According to the widening extent of bile duct diameter, all patients are classified into mild (0.6～0.8 cm) and a significant broadening group (> 0.8cm). Hepatic artery flow spectrum from the first hepatic portal vein near the door, some obese or seriously interfere with the trunk show flatulence unclear who will get the start right hepatic artery Department. Select a clear, complete and continuous flow spectrum in three cardiac cycles and records of peak flow velocity(PSV) and resistive index (RI). Statistical analysis:All data were analyzed statistical software applications SPSS 13.0, Quantitative indicators among the three groups analysis of variance was used to compare the measured data with the x±S said; Between two groups using t test; Observe the linear relationship between two quantitative indicators using a general linear regression analysis, to scatter, regression equations are listed; Observed linear relationship between the two indicators for correlation analysis, correlation coefficient obtained; P<0.05 that the difference was statistically significant.Results:①Compared to GDCL group and CCL group, the PSV and RI of hepatic artery in BDTS group were significantly higher, the difference is statistically significant (P<0.05). There were no statistically significant difference between GDCL group and CCL group (P>0.05) (FRI=6.863, P<0.05; FPSV=13.528, P<0.05), BDTS group PSV:91.15±23.38, RI:0.81±0.06; GDCL Group PSV:66.28±16.56, RI:0.74±0.06; CCL Group:PSV:64.69±17.44, RI:0.75±0.07.②There were no statistically significant difference between mild and significant broadening groups in PSV and RI of hepatic artery (P>0.05). Two-dimensional ultrasonography combined with hepatic artery RI, PSV can be used as ultrasound to determine the important nature of bile duct lesions secondary target.③In 59 cases of pathologically confirmed by ERCP, the PSV and RI of hepatic artery in bile duct tumor lesions were significantly higher than inflammatory lesions (P<0.05).Conclusion:①Color Doppler ultrasound assessment of hepatic artery parameters has an important value in differential diagnosis of bile duct lesions.②The widening extent of bile duct diameter can not serve as a indicator to judge the nature of bile duct lesions.
