Apple-peel intestinal atresia

Apple-peel intestinal atresia, also known as type IIIb or Christmas tree intestinal atresia, is a rare form of small bowel atresia in which the duodenum or proximal jejunum ends in a blind pouch and the distal small bowel wraps around its vascular supply in a spiral resembling an apple peel. Often a vast segment of small bowel is absent.

While apple-peel intestinal atresia is usually reported as an isolated malformation, it has been associated with malrotation. Additionally, syndromic association has been reported with microcephaly and ocular anomalies.
