endoscopy

(en-dos'ko-pe) [ endo- + -scopy]
Inspection of body organs or cavities by use of an endoscope. Although endoscopy is well tolerated by nearly all patients, major complications, e.g., perforation of the organ being examined, bleeding, difficulty breathing, chest pain, or adverse anesthetic reactions occur rarely.

autofluorescence endoscopy

An enhanced form of endoscopic examination of the lining of an organ in which the organ is examined with light with specific limited wavelengths. This monochromatic light helps distinguish normal tissues from precancerous or malignant tissues and may increase the likelihood of obtaining a useful biopsy specimen during endoscopy.

capsule endoscopy

Abbreviation: CE.
Endoscopy of the gastrointestinal tract with a pill that contains a miniature camera. The pill is swallowed by the patient and travels through the gut unaided. CE is used to examine the small intestine, which is difficult to reach with standard upper endoscopy or with colonoscopy. CE can be used to identify otherwise occult sources of gastrointestinal bleeding.

CAUTION!

In patients with gastrointestinal strictures the camera may become lodged in the narrows and occasionally may need to be removed surgically.
Synonym: video endoscopy; wireless capsule endoscopy

double balloon endoscopy

Endoscopy to evaluate and treat sources of gastrointestinal bleeding within the small bowel. It allows visualization of successively deeper segments of the small bowel by catching the bowel wall with one balloon (located on an overtube that surrounds the endoscope) and then advancing the endoscope ahead of it. When the endoscope reaches a new section of bowel, a new balloon is inflated, fixing the bowel in place. The overtube balloon is deflated, and the overtube is advanced until its balloon is reinflated. The process is repeated until the scope has been successively moved through the entire small intestine, visualizing it fully.
Synonym: push-and-pull endoscopy

magnification endoscopy

The use of digital and optical magnification to enhance the visualization of small lesions within an organ during endoscopy. It is used to identify changes in the esophagus suggestive of Barrett esophagus and may be combined with other imaging techniques (e.g., the spraying of the lining of the examined organ with acetic acid or methylene blue or the illumination of the organ with fluorescent chemicals).

push-and-pull endoscopy

Double balloon endoscopy.

video endoscopy

Capsule endoscopy.

wireless capsule endoscopy

Capsule endoscopy.

Wireless capsule endoscopy

A newer method of examining the small bowel by means of a capsule swallowed by the patient. The capsule contains a miniaturized lens and an antenna that transmits information to a belt-pack recorder worn by the patient during the day.
