Clinical diagnostic value of CT and color Doppler ultrasound in acute pancreatitis complicated with fatty liver
Objective To explore and compare the clinical value of CT and color Doppler ultrasound in the diagnosis of acute pancreatitis(AP)complicated with fatty liver disease(FLD).Methods A total of 80 patients suspected of AP complicated with FLD who were admitted to zhongda Hospital Lishui Branch Affiliated to Southeast University from January 2020 to December 2021 were included.All patients underwent CT examination and color Doppler ultrasound imaging examination,and the imaging characteristics of the two examination methods were recorded.The accuracy,specificity,and sensitivity of the two examination methods in diagnosing AP patients were calculated.The grading of the two examination methods in diagnosing FLD was recorded.Results Combined with the patient's clinical manifestations,serum amylase activity,lipase activity,and imaging manifestations,76 of the 80 suspected cases were diagnosed with AP.CT examination results showed that 73 patients presented typical imaging features of AP,with an accuracy of 93.75%,specificity of 75.00%,and sensitivity of 94.74%;color Doppler ultrasound examination results showed that 70 patients presented ultrasound imaging features of AP,with an accuracy of 87.50%,specificity of 50.00%,and sensitivity of 89.47%.There was no statistically significant difference in accuracy,specificity,and sensitivity between the two groups(P>0.05).In the diagnosis of FLD,CT examination results showed that 68 patients(85.00%)presented typical imaging features of FLD,with 25 cases(31.25%)of mild FLD,30 cases(37.50%)of moderate FLD,and 13 cases(16.25%)of severe FLD.Color Doppler ultrasound examination results showed that 64 patients(80.00%)presented ultrasound imaging features of FLD,with 24 cases(30.00%)of mild FLD,28 cases(35.00%)of moderate FLD,and 12 cases(15.00%)of severe FLD.There was no statistically significant difference between the two imaging methods in diagnosing FLD(P>0.05).Conclusion Both CT and color Doppler ultrasound can obtain high accuracy in diagnosing AP complicated with FLD,and there is no statistically significant difference in the diagnostic effects of the two methods.In clinical application,the appropriate imaging examination method can be selected according to the actual situation of the patient.
