Enteroscopy refers to direct visualization of the
small bowel using a
fiber optic endoscope, or other wireless endoscopy system, including
wireless capsule endoscopy.Visualization of the small bowel has posed a challenge to
gastroenterologists due to the difficulty of physically reaching the small bowel anatomically. As the small bowel can be a source of pathology, endoscopy of the small bowel can be a useful diagnostic technique.Traditional
gastroscopes can visualize the proximal and sometimes distal
duodenum. Longer gastroscopes or sometimes colonoscopes used for upper endoscopy can visualize the proximal
jejunum. This technique is referred to as push endoscopy.
