Abstract
During the years 1936 through 1978, 60 cases received surgical intervention for alveolar echinococcosis of the liver. The re-sectability and operative mortality rate were 64.0% (16/25) and 43.8% (7/16) before 1968, but 54.3% (19/35) and zero (0/19) thereafter. Establishment of clinical staging and criteria for justifying radical resection of a given lesion, combined with systematic evaluation of all hepatic vasculatures, contributed to improvement of the result. The long-term prognosis of the disease, unless resected, has been exclusively poor. A mass screening program, which became possible by the development of serologic tests, has covered a population of over 140,000 in the endemic area and been of value in detecting the disease in its early developmental stage. The disease should be recognized even in currently unaffected areas since the cestode has a fairly wide geographic distribution including the United States.
