Jejunal atresia

Disease Overview

Jejunal atresia is a birth defect in a newborn characterized by partial or complete absence of the membrane connecting the small intestines to the abdominal wall (the mesentery). It causes a portion of the small intestines (the jejunum) to twist around an artery that supplies blood to the colon (the marginal artery). This leads to an intestinal blockage or “atresia.” Common symptoms in the newborn include feeding difficulties, failure to thrive, vomiting bile (a yellowish-green fluid), abdominal swelling, and/or absence of bowel movements after birth. It typically occurs sporadically in people with no family history of the condition; however, more than one family member can rarely be affected, suggesting that there may be a genetic component in some cases. Jejunal atresia is typically treated with surgery.[12437][9060]
