Study on the correlation between CT and color Doppler ultrasound diagnostic parameters and the condition and prognosis of patients with acute pancreatitis complicated with fatty liver
Objective To study the correlation between CT and color Doppler ultrasound diagnostic parameters and the condition and prognosis of patients with acute pancreatitis(AP)complicated with fatty liver.Methods A total of 150 AP patients with fatty liver admitted to The First Affiliated Hospital of Chengdu Medical College from January 2021 to December 2023 were selected.According to the condition of the patients,they were divided into mild,moderate and severe groups;according to the prognosis of the patients,they were divided into survival group and death group.The characteristics of CT and color Doppler ultrasound parameters of patients with different conditions and prognosis were compared,and the correlation between CT and color Doppler ultrasound parameters and the condition and prognosis of patients was summarized by Logistic multivariate regression analysis.Results Among the 150 AP patients with fatty liver,there were 76 cases of mild AP,44 cases of moderate AP,and 30 cases of severe AP;10 patients died within 28 days of treatment,and the mortality rate was 6.67%.Multivariate analysis showed that severe fatty liver,liver CT value≤40 HU,spleen CT value≥70 HU,L/S≤0.50,and CT showed reduced pancreatic density,perirenal fascia thickening,ascites and CT grading D-E were independent risk factors affecting the condition of AP patients with fatty liver(P<0.05);age≥60 years,severe fatty liver,liver CT value≤40 HU,spleen CT value≥70 HU,L/S≤0.50,and CT showed perirenal fascia thickening and CT grading D-E were independent risk factors affecting the prognosis of AP patients with fatty liver(P<0.05).Conclusion CT and color Doppler ultrasound signs and parameters can provide certain reference for the condition evaluation and prognosis prediction of AP patients with fatty liver.
