Endoscopy
Treatment
Endoscopes can also be used for treatment. A doctor can pass different types of instruments through a small channel in the endoscope. For example, an electric probe at the tip of the endoscope can be used to destroy abnormal tissue and small growths or to close off a blood vessel. A needle at the tip can be used to inject medications into dilated veins in the esophagus and stop their bleeding. Endoscopes are also used to place stents, drain cysts, remove foreign bodies, place feeding tubes, and remove polyps.
