Gastric atresia
Gastric atresia is a congenital defect with complete occlusion of the pyloric outlet of the stomach.[1]
Cause
[edit]Gastric atresia is a birth defect. It can be genetic, inherited in an autosomal recessive manner, and associated with conditions like Down syndrome and junctional epidermolysis bullosa (medicine).[2] In about 60% of cases, the outlet of the stomach is covered by a membrane. In around 35% of cases, solid tissue blocks the outlet. In the remaining cases (less than 10%), there is a complete separation of the stomach and the small intestine.[3]
Diagnosis
[edit]Polyhydramnios is often seen during pregnancy, and prenatal diagnosis is common.[3] Infants with gastric atresia will exhibit forceful vomiting upon the first feeding. Imaging is required for diagnosis.[2]
Treatment
[edit]Treatment is surgical and involves removing or bypassing the obstruction.[2][3]
Epidemiology
[edit]It is seen in approximately 1 in 100,000 live births.[4]
