Abstract
Extrahepatic biliary atresia (EHBA) is an infrequent disease confined to early infancy. Its aetiology is not clear, but an infectious agent has been implicated. Demonstration of a time-space clustering would support this hypothesis. Therefore, we investigated the time-space distribution of all 89 cases of EHBA born in a 10-year period in the Netherlands. We carried out a similar study in West Germany and analysed 130 cases of EHBA, born between 1969 and 1986, from 4 paediatric surgical centres. Analysis of these cases did not reveal any evidence for clustering in specific years or in a specific period of the year. The places of birth of the patients also were randomly distributed over rural areas, villages and towns. Neither did a method to reveal time-space interaction give any support for clustering. This random distribution of patients with EHBA suggests that EHBA could be pathogenetically a heterogeneous disease.
