Abstract:
Agenesis of the dorsal mesentery is a rare occurrence that usually presents in children. It is associated with proximal small-bowel malrotation as well
as high jejunal atresia with discontinuity of the small bowel. We present a case report of an adolescent presenting with clinical features of proximal
small-bowel obstruction (confirmed on imaging) as well as acute pancreatitis. At laparotomy, he was found to have no dorsal mesentery, without
small-bowel atresia, and the duodenum was fixed to the posterior abdominal wall. The patient recovered well and remained symptom-free.
