Atresia and Stenosis
The gastrointestinal tract can be considered as a simple tube or pipe, anything which blocks the tube (at different levels) can have different effects.
- Esophageal Atresia
- Duodenal Atresia and Stenosis
- Pyloric Stenosis
- Extrahepatic Biliary Atresia
- Anorectal Atresia
Duplication of tract
Persistent Vitelline Duct
Meckel's Diverticulum
Abnormal Gut Rotation
Midgut Volvulus, Situs Inversus
Organ Abnormalities
Extrahepatic Biliary Atresia, Accessory Pancreatic Tissue, Anular Pancreas, Accessory Spleen
Motility Disorders
Hirschprung's disease - abnormalities of neural crest migration.
Related Abnormalities
Abdominal Wall Defects
gastroschisis is a developmental abnormality occurs due to an abdominal wall defect, that allows the evisceration of the intestine.
Cleft lip
An abnormality of face development leading to an opening in the upper lip. Clefting of the lip and or palate occurs with 300+ different abnormalities. Depending on many factors, this cleft may extend further into the oral cavity leading to a cleft palate. In most cases clefting of the lip and palate can be repaired by surgery. (More?

Cleft palate
An abnormality of face development leading to an opening in the palate, the roof of the oral cavity between the mouth and the nose. Clefting of the lip and or palate occurs with 300+ different abnormalities. In most cases clefting of the lip and palate can be repaired by surgery. (More?

Galactosemia
An enzyme deficiency disorder. The enzyme galactose-1-phosphate uridyl transferase metabolizes galactose in milk sugar. (More? Prenatal Diagnosis | Neonatal Screening | MedlinePlus - Galactosemia)

Abnormalities and Development
- How these abnormalities may be generated in development.
- When they first occur.
- How can we detect these abnormalites.
- Do the abnormalites have a direct or indirect effect on the GIT.
- How serious to the embryo, fetus, newborn, child and adult are these conditions.
- What therapeutics are available for these conditions.
