apple peel atresia
A severe form of jejunal atresia where the distal small bowel spirals around a single mesenteric vessel, resembling an apple peel.
Full Definition
Apple peel atresia, also known as Christmas tree deformity or Type IIIb jejunal atresia, is a distinctive form of small bowel atresia characterized by proximal jejunal atresia with the distal small bowel receiving blood supply from a single ileocolic or right colic artery. The distal bowel appears to spiral around this vessel, creating the characteristic appearance that gives the condition its name. This configuration often results in significant bowel length loss and may be associated with short gut syndrome. The condition carries increased operative complexity and higher risk of postoperative complications compared to other forms of intestinal atresia.
Usage
Usage note: Descriptive term based on characteristic intraoperative appearance.
