Gastrochisis is an abdominal wall anterior defect that involved extrusion of fetal intestines. Occur in 0.13 to 1.4 per 10.000 live births. Review from the ultrasound literature report small bowel diameter over 11 mm to predict adverse neonatal outcome. This study want to review and correlate ultrasound markers with adverse neonatal outcome. Datas from 7516 deliveries between 2006–2007 was colleted. From this data's 12 fetuses had gastroschisis. Ultrasound report was made by taking measurements of the free loop in the small bowel (length and the anteroposterior diameter) and 3D images. All studies were performed using an 3700 ALOKA ultrasound system. Data's were analyze in computer statiscal program (Epiinfo). Incidence of gastroschisis was 15, 97 per 10.000 live births. Standard deviation is 8, 65 to 28.73 per 10,000 alive births. The mean of the length in the free loop was 63 mm. The low value was 44 mm and the maximum value of the free loop was 82 mm. The mean of the anteroposterior diameter was 21.2 mm. The low value was 17 mm and the maximum value of the free loop in the anteroposterior diameter was 29 mm. (see image 1). Mean fetal weigh 2099 grams. Mean gestational age to delivery 32.2 weeks. Twenty percent of the newborn at the time of the surgery had ischemia of the small bowel. Twenty percent of the newborn had intestinal obstruction. Mean time to full oral feedings 21.8 days. Mean overall length of hospital stay 35.4 days. 3D pictures are correlated with the maximum value of free loop for ischemia in the newborn surgery. Gastrochisis Incidence is increasing. Measurement of the free loop in the small bowel is a good marker to prevent ischemia (63 mm per 44 mm). Preterm delivery gives better outcome to the newborn with Gastroschisis (32.2 weeks). 3D ultrasound is a good marker too to identifique ischemia. Is necessary more data's to confirm this findings.
