Duodenal Atresia Overview
Learn About Duodenal Atresia
Duodenal atresia is a condition in which the first part of the small bowel (the duodenum) has not developed properly. It is not open and does not allow the passage of stomach contents.
The cause of duodenal atresia is not known. It is thought to result from problems during an embryo's development. The duodenum does not change from a solid to a tube-like structure, as it normally would.
Many infants with duodenal atresia also have Down syndrome. Duodenal atresia is often associated with other birth defects.
Symptoms of duodenal atresia include:
- Upper abdominal swelling (sometimes)
- Early vomiting of large amounts, which may be greenish (containing bile)
- Continued vomiting even when infant has not been fed for several hours
- No bowel movements after first few meconium stools
A tube is placed to decompress the stomach. Dehydration and electrolyte imbalances are corrected by providing fluids through an intravenous tube (IV, into a vein). Checking for other congenital anomalies should be done.
Surgery to correct the duodenal blockage is necessary, but not an emergency. The exact surgery will depend on the nature of the abnormality. Other problems (such as those related to Down syndrome) must be treated as appropriate.

After surgery, there may be complications such as:

- Problems with movement through the intestines

Contact your health care provider if your newborn is:
- Feeding poorly or not at all
- Vomiting (not simply spitting up) or if the vomit is green
- Not urinating or having bowel movements
There is no known prevention.
Summary: Congenital duodenal atresia is a common cause of neonatal obstruction affecting 1 in 5000-10000 neonates. Laparoscopic management of this malformation is becoming increasingly common. However, few comparative studies exist and are often monocentric including few patients. This study will be multicentric, international and comparative to determine the place of laparoscopic surgery in the management...
