Endoscope, endoscopy
An endoscope as used in the field of gastroenterology is a thin flexible tube which uses a lens or miniature camera to view various areas of the gastrointestinal tract. When the procedure is performed to examine certain organs such as the bile ducts or pancreas, the organs are not viewed directly, but rather indirectly through the injection of x-ray dye. The performance of an exam using an endoscope is referred by the general term endoscopy. Diagnosis through biopsies or other means and therapeutic procedures can be done with these instruments.

endoscope
[en′dəskōp′]
Etymology: Gk, endon + skopein, to look
an illuminated optic instrument for the visualization of the interior of a body cavity or organ. Instruments are available in varying lengths. The fiberoptic endoscope has great flexibility, reaching previously inaccessible areas. Although the endoscope is generally introduced through a natural opening in the body, it may also be inserted through an incision. Instruments for viewing specific areas of the body include the bronchoscope, cystoscope, gastroscope, laparoscope, otoscope, and vaginoscope. See also fiberoptics. endoscopic, adj.
endoscope,
n an illuminated instrument that is used to investigate the interior of the intestinal lining via the mouth.

Endoscope.
endoscope
an instrument used for direct visual inspection of hollow organs or body cavities. Specially designed endoscopes are used for such examinations as bronchoscopy, cystoscopy,gastroscopy and proctoscopy.
Although the design of an endoscope may vary according to its specific use, all endoscopes have similar working elements. The viewing part (scope) may be a hollow metal or fiber tube fitted with a lens system that permits viewing in a variety of directions. The endoscope also has a light source, power cord and power source. Accessories that might be used with an endoscope for diagnostic or therapeutic purposes include suction tip, tubes and suction pump; forceps for removal of biopsy tissue or a foreign body; and electrode tip for cauterization.

endoscope
Instrument designed to examine cavities which are not accessible for direct examination with the eye. It usually incorporates fibre optics to increase the flexibility of the instrument. Examples: a laryngoscope which is introduced through the mouth to examine the larynx; an ophthalmic endoscope to examine the intraocular structures by inserting a fibre optics system through the sclera, as may be used in ocular surgery.
endoscope
A semirigid or flexible device with a long firm coil that is inserted into the region of interest, which has a light source, an optical system for viewing mucosa, camera, and a channel that allows insertion of sampling
devices–eg alligator forceps, cup forceps, or curette for obtaining biopsies or surgical instruments to perform simple–minor surgeries. See Needle endosope, Sigmoidoscope, Stereoendoscope.
