Abstract:

To analyze the 1 917 cases of hepatic echinococcosis diagnosed by ultrasound in Qinghai Province retrospectively, in order to understand the classification and epidemiological characteristics of the disease, providing basis for prevention and control and for evaluations of control effects. Primary information were collected of the 1 917 cases of hepatic echinococcosis diagnosed by abdominal ultrasound scanning during the period from January 2013 to March 2019 in the Qinghai University Affiliated Hospital. The information collected were analyzed by χ ² test with regard to the infection type, gender, age and ethnicity using SPSS 19.0. Among the 1 917 cases, the cases of cystic, alveolar and mixed was 1 041 (54.3%), 867 (45.2%), and 9 cases (0.5%), respectively, with the difference being statistically significant (P < 0.05). Of the 1 917 cases, 914 (47.7%) were males and 1 003 (52.3%) were females (P > 0.05). The numbers of patients in the age groups of 0-19 years, 20-39 years, 40-59 years and ≥ 60 years were 148 (7.7%), 739(38.6%), 735 (38.3%) and 295 (15.4%), respectively, with significant difference (P < 0.05).

Among the total, the number of consolidatory cystic echinococcosis(340, 32.7%) and infiltrative elveolar echinococcosis (442, 51.0%) are the highest.
