Type : Phenotype or locus, molecular basis unknown;
Alternative titles and symbols : Apple peel small bowel syndrome; APSB; Apple peel syndrome;
Description : Jejunal atresia is the most common cause of bowel obstruction in the newborn. In this
condition, because of agenesis of the mesentery, the distal small bowel comes straight
off the caecum and twists around the marginal artery, suggesting a maypole, a Christmas
tree, or an apple peel at operation. Obliteration of the superior mesenteric artery
may underlie this malformation.;
