A Rare Case of Apple Peel Ileal Atresia With Coexisting Colonic Atresia: Surgical Management and Outcomes.

Ileal atresia is one of the most frequent causes of congenital intestinal obstruction. Type IIIb, also known as apple peel atresia, is the least common subtype. Colonic atresia is a rare anomaly that can also cause neonatal intestinal obstruction. Both can coexist with other atypical malformations, further complicating diagnosis. The surgical management of these two gastrointestinal malformations differs between centers, and no standardized procedural guidelines currently exist. We present a case of a neonate born with apple peel ileal atresia coexisting with transverse colonic atresia, both successfully treated with primary anastomoses. The postoperative course was uneventful, and the patient was discharged with full oral feeding and regular bowel movements.
