ABSTRACT

Jejunal atresia is a leading cause of neonatal intestinal obstruction, most commonly resulting from intrauterine vascular accidents. Intraluminal mucosal diaphragms and enteric duplications are rare congenital anomalies, and their coexistence is exceptional.
We report the case of a full-term newborn presenting with early bilious vomiting and abdominal distension. Imaging suggested proximal intestinal obstruction. Surgical exploration revealed type I jejunal atresia caused by a mucosal diaphragm, associated with a cystic jejunal duplication sharing a common muscular wall. Segmental resection and primary anastomosis were performed with a favorable outcome.
This rare association highlights the importance of thorough intraoperative exploration in neonatal intestinal obstruction. Multiple embryological mechanisms may coexist, complicating both diagnosis and management.
