Prevalence of gastroschisis at birth: retrospective study

Abstract
We selected registries that provided information on at least 10 consecutive years including 1998 and analysed births occurring between 1974 and 1998 from 19 registries (see bmj.com). The numerators of the prevalences (see table) include liveborn and stillborn babies with gastroschisis (isolated or associated with other defects); denominators are the total numbers of births. Registries used their own diagnostic criteria and definitions of gastroschisis and omphalocele, but we found no substantial differences.
