endoscopyExamination of the body's interior through an instrument inserted into a natural opening or an incision, usually as an outpatient procedure. Endoscopes include the upper gastrointestinal endoscope (for the esophagus, stomach, and duodenum), the colonoscope (for the colon), and the bronchoscope (for the bronchial tubes). With fibre optics, much more maneuverable instruments can reach formerly inaccessible sites, while causing much less discomfort. Attachments can take tissue samples, excise polyps and small tumours, and remove foreign objects. How to thank TFD for its existence?

The development of angled endoscopes has given surgeons a new tool for examining anatomic structures in the middle ear (figure 1). Wireless capsule endoscopes are not only much less invasive, but seem to work better at detecting certain diseases of the intestines than traditional periscope-like cameras. One of the problems that doctors have in the gastrointestinal tract is that there is a large part of it--most of the small intestines--that they cannot access with standard endoscopes. |
