[Clinical characteristics of 175 cases with advanced hepatic alveolar echinococcosis]

To investigate the clinical characteristics of patients with advanced hepatic alveolar echinococcosis, so as to provide more evidence for the diagnosis and treatment of advanced hepatic alveolar echinococcosis.

The clinical records of 175 cases with hepatic alveolar echinococcosis admitted to the Affiliated Hospital of Qinghai University from 2012 to 2017 were retrospectively reviewed.

Among the 175 cases with hepatic alveolar echinococcosis, the male to female ratio was 1∶1.6, and the mean age was (38.6 ± 12.9) years (range, 11 to 69 years). 93.7% of the patients (164 cases) were Tibetan, and 79.4% (139 cases) were from Guoluo Prefecture. 73.7% (129 cases) were herdsmen, and 58.3% (102 cases) were illiterate. The major clinical symptoms included upper abdominal pain, yellowing of skin and mucosa, and scleral icterus. 69.1% of the lesions were located in bilateral livers, and 63.4% of the cases have 2 and more lesions. 53.7% of the cases have their inferior vena cava involved by the lesions. In addition, the most affected neighboring organ was diaphragmatic muscle (21.7%), and lung was the most affected distant metastatic site (40.6%).

Advanced hepatic alveolar echinococcosis is highly prevalent in Guoluo Prefecture, Qinghai Province. Screening of this disease is required in this region and rational treatment scheme should be developed.
