How is an Endoscopy performed?
The doctor puts the endoscope into your mouth. He or she can ask you to swallow, as the scope passes through your throat. You may feel some pressure in your throat but you do not necessarily experience Pain. Once the endoscope passes your throat you cannot speak, but you can make noises. The endoscope should not mess with the respiration.
A small camera at the tip transmits pictures to the video display. Your doctor will watch the monitor look into your digestive tract for abnormalities. If there are abnormalities in your digestive tract, your doctor can record pictures for subsequent tests. Gentle air pressure can be injected into the esophagus to inflate the digestive tract. This allows free movement of the endoscope. It helps the doctor to inspect the folds of the digestive tract more easily. Your doctor can pass special surgical equipment through the endoscope to retrieve a tissue sample or remove a polyp, if necessary. Your doctor will use the video display to direct and control the devices. The endoscope is slowly retracted through your mouth after your doctor has finished the exam. Depending on the case, an Endoscopy usually requires about 15 to 30 minutes.
