AbdAllah, Prospective study assessing the incidence of intestinal mucosal after complex operations for congenital heart disease.  Long-term project that will determine whether determination of urinary iFABP can aid in decisions regarding the introduction of enteral nutrition.
  6. Impact of intestinal mucosal injury on the duration of ileus in gastroschisis. G. Gollin, Jon Mayhew, Prospective study of infants with gastroschisis.  Urinary iFABP is determined during reduction and after fascial closure and correlated with the time until full feedings are tolerated.  Specimens have been collected from 50 infants.  Clinical data needs to be collected
