Sphincter of Oddi incompetence associated with duodenal stenosis in a newborn: A case report

Abstract

Newborn incompetence of the sphincter of Oddi is rare. While there are many causes of reflux of air or ingested contrast material into the biliary tree in adults, in the newborn, it is usually due to incompetence of the sphincter of Oddi associated with partial or complete duodenal obstruction. This paper presents upper gastrointestinal series findings of incompetence of the sphincter of Oddi associated with duodenal stenosis in a 3-day-old newborn. If pneumobilia is identified in the newborn, although the possibility is low, clinicians should consider incompetence of the sphincter of Oddi with duodenal obstruction as well as portal vein gas.
