Atresia is a congenital condition where a normal opening or passage in the body is absent or closed.
This can affect different organs and often requires surgical treatment shortly after birth. Atresia can interfere with essential functions like digestion or breathing, making early diagnosis and care critical.
Types of atresia
There are several forms of atresia, each affecting a different part of the body.
Types of atresia include:
- Biliary atresia: Affects the bile ducts
- Duodenal atresia: Affects the small intestine
- Esophageal atresia: Affects the esophagus
- Pulmonary atresia: Affects the pulmonary valve of the heart

Biliary atresia
Biliary atresia occurs when the bile ducts inside or outside the liver are blocked or absent, preventing bile from draining into the intestine.
- Symptoms: Jaundice, pale stools, dark urine.
- Treatment: Surgery to restore bile flow and protect liver function.

Duodenal atresia
Duodenal atresia is a blockage in the first part of the small intestine (duodenum), which prevents food from passing through.
- Symptoms: Vomiting, abdominal swelling, feeding difficulties.
- Treatment: Surgical repair to open the passage.

Esophageal atresia
Esophageal atresia is a condition where the esophagus does not connect properly to the stomach, making swallowing impossible.
- Symptoms: Drooling, choking during feeding, breathing problems.
- Treatment: Surgery to connect the esophagus to the stomach.

Pulmonary atresia
Pulmonary atresia is a heart defect where the pulmonary valve does not form correctly, blocking blood flow from the heart to the lungs.
- Symptoms: Cyanosis (bluish skin), breathing difficulties, fatigue.
- Treatment: Specialized cardiac surgery and ongoing care.

Frequently asked questions about atresia
Atresia is a congenital condition where a normal opening or passage in the body is absent or closed. It can affect different organs and usually requires surgical treatment soon after birth.
Four primary types of atresia include biliary, duodenal, esophageal, and pulmonary atresia.
The exact cause is not always known. It often occurs during fetal development and may be associated with genetic factors or other congenital anomalies.
Treatment typically involves surgery to restore normal function. The approach depends on the type of atresia and the child’s overall health.
