Annular pancreas

An annular pancreas is a ring of pancreatic tissue that encircles the duodenum (the first part of the small intestine). The normal position of the pancreas is next to, but not surrounding the duodenum.

Digestive system

The esophagus, stomach, large and small intestine, aided by the liver, gallbladder and pancreas convert the nutritive components of food into energy and break down the non-nutritive components into waste to be excreted.

Endocrine glands

Endocrine glands release hormones (chemical messengers) into the bloodstream to be transported to various organs and tissues throughout the body. For instance, the pancreas secretes insulin, which allows the body to regulate levels of sugar in the blood. The thyroid gets instructions from the pituitary to secrete hormones which determine the rate of metabolism in the body (the more hormone in the bloodstream, the faster the chemical activity; the less hormone, the slower the activity).

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.
