Colonic atresia (large bowel atresia) is a congenital obstruction or underdevelopment of the large intestine. This condition refers to an anomaly in which part of the large intestine is completely closed or a long segment has not developed. It prevents the proper passage of food and digestive fluids. It is a rare congenital condition, occurring in approximately 1 in 15,000 to 20,000 infants. It is mostly detected during routine prenatal ultrasound examinations.

Therefore, families of babies suspected to have duodenal atresia during pregnancy should definitely consult a center with perinatology, pediatric surgery, and neonatal intensive care unit services during pregnancy.

If undetected during pregnancy, colonic atresia is identified immediately after birth. It presents in the newborn with feeding difficulties, vomiting, abdominal distension, and poor general condition. Without urgent intervention, life-threatening complications develop. When food and intestinal fluids cannot pass and accumulate in the bowel segment before the undeveloped section, perforation may occur in that region.

Treatment

The only treatment is surgical. The obstructed section is opened surgically to restore the passage between the large intestines. In experienced centers, this procedure is performed laparoscopically (minimally invasive). Laparoscopic surgery reduces the surgical stress experienced by the newborn. This technique minimizes the risks of complications such as bleeding and intestinal perforation during or after surgery. After the surgery, the baby can start feeding earlier and can be placed with the mother sooner. However, if the baby’s overall condition does not allow for laparoscopic surgery, open surgery should be performed.

Colonic atresia is an important congenital anomaly of the digestive system in infants and requires surgical intervention. Early diagnosis and appropriate treatment ensure healthy growth and development of the infant. Careful monitoring and management after surgery reduce the risk of complications. Therefore, when this condition is suspected during pregnancy, it is essential to have multidisciplinary follow-up and treatment (including obstetrics and perinatology, neonatal intensive care, and pediatric surgery) at an experienced center. This approach is crucial for the newborn to gain health earlier and more safely.

In case of any concerns, consulting a pediatric surgeon is the most appropriate approach. Your doctor will determine the best treatment and follow-up plan according to your child’s specific condition.
