Neonatal<unk>  is a cause of functional<unk>  obstruction in newborn infants.<unk>  is subset of meconium plug syndrome in which an enema demonstrates an apparent transition zone between the dilated and the normal-to-decreased caliber distal<unk>  at the splenic flexure. There is a high association of maternal diabetes.
Patient #1: Failure to pass meconium<unk>  must be differentiated from other diseases that cause a failure to pass meconium or abdominal distension in infants, including meconium plug syndrome, and congenital hypothyroidism.
Transient intestinal obstruction for 1-2 days after birth.
Obstruction is functional due to dilated<unk>  and delayed passage of feces.
Usually seen in premature infants.
Reduced caliber of the<unk>  starting from splenic flexure and going down, causing intestinal obstruction.
Characterized by a sudden change of the<unk>  diameter.
Usually associated with gestational diabetes.
Failure to pass meconium due to failure of intestine recanalization.
Proximal lesions have an earlier onset of symptoms than distal lesions.<unk> ic atresia may affect normal children or may be associated with other abnormalities as Hirschsprung's disease or gastroschisis.
Intestinal obstruction due to inspissation of meconium in the distal ileum.
Most cases of meconium ileus are secondary to cystic fibrosis.
Typically presents with failure to pass meconium and abdominal distension with or without vomiting.
Meconium ileus may first present with complications, including perforation and volvulus.
Most infants are born asymptomatic.
Symptoms, if present, may include, but not limited to:
Macroglossia
Hoarse cry
Umbilical hernia
Puffy facies
Increased head circumference
Hypothermia
