Duodenum: The first part of the small intestine. Located between the stomach and the ileum. After foods combine with stomach acid, they descend into the duodenum where they mix with bile from the gall bladder and digestive juices from the pancreas.

Duodenal stent: Stents are used to unblock and keep open tube-shaped structures in the body, including the ureters (the tubes that drain urine from the kidneys to the bladder). illustration

During a duodenal stent placement, a tiny tube referred to as a stent is placed to prop open an obstruction in the duodenum (first section of the small intestine) which may allow fluid and food to pass more easily and also to keep the duodenum from becoming obstructed again.
