What is an endoscope?

An endoscope is a long, thin tube with an attached light and tiny camera. It is used in minimally invasive surgery procedures.

Depending on the type of procedure being done, a surgeon may insert an endoscope into a natural body opening (such as the mouth and down the throat) or into a small incision in the skin.

The endoscope projects an image of the interior of the body onto a screen so that the surgeon can have a clear, magnified view of the area during surgery.
An endoscope is a long fiber-optic tube with a camera and a light at its tip, along with a small channel through which gastroenterologists pass instruments into the gut to perform a variety of treatments while viewing images on a monitor. “Through the endoscope, we can now perform biopsies, cut things, cauterize and even seal up small holes,” explains V. Raman Muthusamy, M.D., associate clinical professor of medicine at the David Geffen School of Medicine at UCLA and director of interventional endoscopy.
An endoscope is a flexible tube with a tiny camera and light at the end so a physician can view the inside of the upper gastrointestinal tract. As the physician moves it through the upper GI tract, electronic signals are transmitted from the scope to a computer that displays the image on a video screen. An open channel in the scope allows other instruments to be passed through it to take tissue samples, remove polyps and perform other exams.
An endoscope consists of a flexible tube, which is passed into the digestive tract to provide a video image, and a control section, which allows the endoscopist to maneuver the tip of the flexible tube in a precise manner.

Within the tube are the electronics necessary to obtain the video image, cables that allow control of the flexible tip, and channels that permit the passage of devices to sample tissue, stop bleeding, or remove polyps. The endoscope is a complex but durable instrument and is safe for use in thousands of procedures.
