title: Gastroschisis: can antenatal ultrasound predict infant outcomes?
abstract: OBJECTIVE
  To test previously proposed but unproven antenatal ultrasound prognostic criteria in fetal gastroschisis.
  
  
  METHODS
  Thirty consecutive gastroschisis-affected pregnancies and their outcomes were reviewed retrospectively. Data were tabulated by review of antenatal ultrasound videotapes, with blinded comparison to indicators of short- and long-term infant outcomes obtained from the medical records. Criteria of previous reports were applied to these data, focusing on their ability to prognosticate effectively.
  
  
  RESULTS
  Applying a criterion of 10 mm bowel dilatation proved minimally useful in prognosticating infant outcomes. However, a stricter 17-mm criterion for clinically important bowel dilatation provided prognostic information, with remarkable improvement in specificity (75 versus 37%) and positive predictive value (55 versus 37%) for infant morbidity, with comparatively little loss of sensitivity (71 versus 85%).
  
  
  CONCLUSIONS
  Bowel dilated more than 17 mm on antenatal ultrasound appears to be associated with increased short- and long-term infant morbidity. Whether this finding warrants obstetric intervention in the preterm gastroschisis-affected pregnancy with substantial bowel dilatation remains to be determined.
