During an upper endoscopy process the patient will be asked to lie down on a table on his back or on his side. Sedation will be given for an anaesthetic will be sprayed in the mouth to numb the throat. The flexible endoscope which is a long, flexible tube (endoscope) is inserted in the mouth.
The doctor will ask the patient to swallow as the flexible endoscope scope passes down the throat and it then enters down your oesophagus. A tiny camera at the tip of the endoscope transmits images to a video monitor in the exam room. In the endoscopy procedure a gastroenterologist watches the images on a monitor to look for abnormalities in your upper digestive tract. Air pressure may be fed into the oesophagus to inflate the digestive tract which allows the endoscope to move freely, during the endoscopy procedure.
