General Considerations
- Obstruction of the small bowel in the terminal ileus from impacted meconium
- May develop in utero and manifests within 48 hours of birth
- Meconium is normally evacuated within first 6 hours
- Earliest sign of cystic fibrosis
- Autosomal recessive
- Predominantly Caucasians
- Diseased exocrine gland function affecting primarily the lungs and the pancreas
- May also be seen with other pancreatic disease such as stenosis of the pancreatic duct
- In a few cases, the pancreas is normal and there is decreased intestinal motility
