A medical device that performs the visual examination of the duodenum by means of an endoscope.
The duodenum is the first section of the small intestine in most higher vertebrates, including mammals, reptiles, and birds. In fish, the divisions of the small intestine are not as clear and the terms anterior intestine or proximal intestine may be used instead of duodenum.
The duodenum precedes the jejunum and ileum and is the shortest part of the small intestine, where most chemical digestion takes place. The name duodenum is from the Latin duodenum digitorum, or twelve fingers' breadths.
In humans, the duodenum is a hollow jointed tube about 25-30 cm (10-12 in) long connecting the stomach to the jejunum.
