Annular pancreas

Annular pancreas is an abnormal ring or collar of pancreatic tissue that encircles the duodenum (the part of the small intestine that connects to stomach). This portion of pancreas can constrict the duodenum and block or impair the flow of food to the rest of the intestines. Symptoms from annular pancreas are nausea, vomiting, feeling of fullness after eating, and feeding problems in newborns. Surgical bypass of the obstructing segment of the duodenum is the usual treatment for this disorder.
