2) Urinary Tract
What is the difference between major and minor omphalocele?
Minor= less than 4cm
Major= greater than 4cm
What is Bechwith-Wiedeman Syndrome?
This is an overgrowth disorder usually present at birth; it is characterized by an increased risk of childhood cancer and congenital anomalies, including:
1) macroglossia (large tongue),
2) macrosomia (above average birth weight and length),
3) midline abdominal wall defects (omphalocele/exomphalos, umbilical hernia, diastasis recti),
4) ear creases or ear pits, and
5) neonatal hypoglycemia
What is Gastrochisis?
Abdominal wall defect right of the umbilicus
What is worse, gastrochisis or omphalocele?
What are the complications of gastrochisis and omphalocele?

- Hypochloremic hypokalemic alkalosis (emesis contains Cl- and K+)
How does biliary atresia present?
Persistent direct hyperbilirubinemia
What is the definitive treatment for biliary atresia?
Transplant (initial surgery, "Kasai" only buys time)
What type of hernia is more common in kids?

Should be fixed ASAP
