A Rare Cause of a Congenital Duodenal Obstruction in The Newborn Period with Nonbilious Vomiting: Annular Pancreas

The various causes of congenital duodenal obstruction (CDO) in the newborn infants are well known but a spesific radiologic diagnosis is difficult to establish. CDOs are classified as extrinsic and intrensic. The annuler pancreas (AP) is involved in extrinsic causes, and is frequently recognised during operation. The annulus is usually consists of a band of pancreatic tissue that completely surrounds the second part of the duodenum. We will describe AP, completely encircled the first portion of the duodenum in the newborn period as a rare cause of CDO with nonbilious vomiting, jaundice and discuss the diagnostic strategies and management
