Meconium Ileus (Failure of Newborn Infant to Past First Stools)

Meconium is the material found in the intestine of a newborn baby. The term meconium ileus means that the baby's first stool (meconium) is blocking the last portion of their small intestine (ileum). An infant with this condition may pass black sticky stool within 24 hours of delivery, be reluctant to feed, and may vomit bile. The baby may experience discomfort due to constipation and trapped air in the bowel.
