RESUMO

Gastroschisis is a defect in the abdominal wall closure affecting the paraumbilical region, mainly in the right side, where small bowel protudes towards amniotic cavity. Bowel contact with amniotic fluid (AF) leads to bowel inflammation and swelling. Imaturity of myoenteric plexus and retardation of intestinal transit. Major neonatal gastroschisis repercussion is delayed hospital ingress time which may lead to severe complication as bacterial translocation and sepsis. Nevertheless the majority of these newborns present intrauterine growth restriction (IUGR) of not yet established cause. The aim of this study is to evaluate the influence of time of bowel exposure to AF on intestinal growth and its repercussion in body weight in a model of gastroschisis in the rat. Two groups of Spreague-Dowley rat fetuses (term=21.5 days) were created. Group I- operated at gestational day 18.5 and Group II- operated at gestational day 19.5, both consisting of 20 triads of gastroschisis (G), control (C) and sham (S). Animals were compared concerning body weight (BW), intestinal weight (IW), and intestinal length (IL) and their relations (IW/BW; IW/IL; BW-IW). For comparison with gastroschisis fetuses
