Jejunal atresia is a genetic disorder in which people are born missing part of the fold of the stomach membrane that connects the small intestine to the back wall of the abdomen. As a result, one of the three portions of the small intestine (the jejunum) twists around one of the arteries of the colon called the marginal artery and causes a blockage (atresia). Jejunal atresia is the most common cause of bowel obstruction in the newborn.[1][2] The defect may occur alone (isolated) or with other birth defects.  The symptoms and treatment vary from patient to patient.
