Clinical and Nutritional Outcomes in Children With Idiopathic Superior Mesenteric Artery Syndrome

Abstract

An aortomesenteric angle <20 degrees is a constant phenomenon in children with idiopathic SMAS. A duodenojejunostomy can effectively relieve the obstructive symptoms, such as anorexia, and improve nutritional status, whereas long-term medical treatment may aid in relieving the clinical symptoms, promoting appetite, and improving nutritional status in pediatric patients with idiopathic SMAS.
