Duodenal atresia
Duodenal Atresia
Duodenal atresia (pronounced: doo-oh-dee-nal a-tre-zee-a) is a congenital defect in which the duodenum, the first part of the small intestine, is closed off rather than being a tube. This condition prevents the normal passage of stomach contents into the rest of the intestine.
Etymology
The term "duodenal atresia" is derived from the Latin "duodenum" (meaning "twelve"), referring to the length of the duodenum (about 12 finger-breadths), and the Greek "atresia" (meaning "lack of an opening").
Symptoms
Symptoms of duodenal atresia typically present shortly after birth and may include vomiting, abdominal distension, and failure to pass meconium (the first stool). The vomit may be green due to the presence of bile.
Diagnosis
Diagnosis of duodenal atresia is often made prenatally through an ultrasound showing a characteristic "double bubble" sign, which represents the dilated stomach and duodenum. Postnatal diagnosis is confirmed through an abdominal X-ray.
Treatment
Treatment for duodenal atresia is surgical. The procedure, known as a duodenoduodenostomy, involves creating a new opening in the duodenum to allow for the passage of stomach contents.
