Definition:
Jejunum is the central part of the small intestine, lying between the duodenum and the ileum. In Jejunal atresia, a part of the small intestine is completely absent or closed. Patients with this disorder are born with a missing stomach membrane fold connecting the small intestine to the abdominal back wall. Consequently, the jejunum twists around the marginal artery causing a blockage. This rare birth defect is also described as malformation of the jejunum.
Diagnosis:
Jejunal atresia is often diagnosed before birth through ultrasound. The ultrasound result will show a dilated segment in the intestine or too much build up of amniotic fluid in the uterus of the mother. Thorough ultrasound study can help in confirming the initial diagnosis.
Treatment:
Infants born with Jejunal atresia will necessitate surgery (laparotomy) almost immediately after birth. If the affected section is small, the surgeon will removed the damaged portion and connect the intestine together. For certain instances, a temporary opening called stoma maybe placed.
Symptoms and Signs:
Jejunal atresia often shows visible signs of vomiting, swollen abdomen, and constipation.
Causes:
Jejunal atresia is a congenital condition, meaning it is present at birth. The cause is unknown, but it is basically due to the malformed development of the bowel during the early stages of pregnancy.
