What is Enteroscopy?
Enteroscopy is the procedure of using an enteroscope for the direct visualization of the small bowel.
Visualization of the small bowel has posed a challenge to gastroenterologists due to the difficulty of physically reaching more distal regions of the small bowel anatomically. As the small bowel can often be a source of pathology, endoscopy of the small bowel can be a useful diagnostic and therapeutic technique.
Traditional gastroscopes can generally visualize the proximal and distal duodenum in the hands of experienced endoscopists but are limited due to the length of the instrument. Pediatric colonoscopes or sometimes dedicated enteroscopes which are much longer than standard gastroscopes can visualize the proximal jejunum. This technique is referred to as push enteroscopy. Due to the length of the small bowel, averaging 4–6 meters in the adult, push enteroscopy is still not effective to adequately visualize large portions of the small intestine.
