What is endoscopy?

Standard upper gastrointestinal endoscopes (120 cm flexible tubes with a light and camera on their tips) are capable of reaching only a foot or so past the stomach into the small intestine. If abnormalities are located within this area, these endoscopes have working channels through which surgical instruments can be passed so that diagnostic and therapeutic procedures such as biopsy and electrocautery can be done.

Many abnormalities of the small bowel, however, lie further along the small intestine beyond the reach of the standard upper gastrointestinal endoscopes. Sometimes a colonoscope, similar to the upper gastrointestinal endoscope but 180 cm in length, can be used to reach a little further into the small intestine, but the additional reach of colonoscopes is limited.

It is not the length of the endoscope that is the most important problem in reaching further into the small intestine. The problem is that the path of the endoscope through the stomach and duodenum is twisty and the endoscopes curl in the stomach. In addition, the small intestine is not fixed in place, and this makes advancement of the endoscopes even more difficult.
