title: Management of meconium-related ileus in very low-birthweight infants.
abstract: BACKGROUND
  Although administration of a water-soluble contrast enema has been recognized to be effective for meconium-related ileus, there have been no definitive management guidelines for very low-birthweight infants.
  
  
  METHODS
  Between 1998 and 2004, 10 infants without cystic fibrosis were treated for meconium-related ileus at Toyohashi Municipal Hospital. Their treatment and clinical course were reviewed retrospectively.
  
  
  RESULTS
  The average gestational age and birthweight of the 10 infants was 27 weeks and 788 g, respectively. The average age at initiation of treatment with a water-soluble contrast enema was 6.8 days. Intestinal obstruction was relieved by the enema in eight of 10 patients, while one underwent laparotomy and one died without any improvement of obstruction. In both neonates for whom the enema failed, rectal examination and rectal irrigation had been performed for several days before the enema was administered at the age of 14 and 15 days, respectively. In contrast, the enema was administered at the age of 1-11 days in neonates for whom this treatment was successful. Obstruction was relieved if the contrast medium reached the distal ileum, but enemas without reflux into the distal ileum failed to improve the obstruction. Contrast medium passed through the ileocecal valve to reach the distal ileum in all procedures done under fluoroscopy, but the medium failed to reach the ileum in most of the procedures done without fluoroscopy.
  
  
  CONCLUSIONS
  Although administration of water-soluble contrast enemas can be effective for meconium-related ileus, reflux into the terminal ileum is essential for bowel obstruction to improve, so it is desirable to perform the procedure under fluoroscopic guidance.
