Abstract:
Objective:To study the clinical application value of B-ultrasound in the diagnosis of hepatic cystic hydatid disease.
Methods:From June 2017 to July 2017, 400 suspected patients with hepatic cystic hydatid disease in the Traditional Chinese Medicine Hospital of Zhoushan were screened in Tibet.All the patients were examined by CT and B-ultrasound.Two CT diagnostics experienced in CT diagnosis and two ultrasound doctors experienced in ultrasound diagnosis were selected to analyze the CT images, B-ultrasound images of the patients, and make the diagnosis.The results of operation or serological examination(clinical diagnosis) were used as the reference.The sensitivity, specificity and accuracy of CT, B-ultrasound in the diagnosis of hepatic cystic hydatid disease were calculated and compared.The consistency between CT, B-ultrasound diagnosis and clinical diagnosis of hepatic cystic hydatid disease was analyzed by consistency test.According to the results of clinical diagnosis, the patients with hepatic cystic hydatid disease were divided into simple cyst type, multiple cyst type, daughter cyst cysts type, cyst calcification type and cyst solid type.The diagnostic coincidence rate of CT, B-ultrasound for different types of hepatic cystic hydatid disease was compared.
Results:A total of 358 cases were confirmed as hepatic cystic echinococcosis by operation and serological examination, and the remaining 42 cases were confirmed as hepatic bubble echinococcosis.The sensitivity, specificity and accuracy of CT in the diagnosis of liver cystic echinococcosis were 94.13%, 83.33%, 93.00%, respectively, which were lower than those of B-ultrasound (98.88%, 97.62% and 98.75%) (χ2=11.978, 4.974, 16.720, all P<0.05). According to the consistency test, the consistency coefficient(Kappa) of CT and B-ultrasound in the diagnosis of hepatic cystic echinococcosis was 0.549 and 0.713, respectively, and the diagnostic consistency between B-ultrasound and clinical diagnosis was better than CT.The diagnostic coincidence rates of B-ultrasound for hepatic cystic echinococcosis of simple cyst type, multiple cyst type, descendant cyst type and cyst consolidation type was higher than those of CT(χ2=13.832, 6.747, 6.331, 5.008, all P<0.05). The diagnostic coincidence rate of B-ultrasound and CT for calcified hepatic cystic echinococcosis had no statistically significant difference (χ2=0.213, P>0.05).
Conclusion:B-ultrasound can accurately diagnose hepatic cystic hydatid disease and can be used as the first choice for diagnosis of hepatic cystic hydatid disease, and B-ultrasound can also differentiate different types of hepatic cystic hydatid disease.The diagnostic value is significant.
