What happens during an endoscopy?
(March 25, 2010)

An endoscopy is a procedure which allows a gastroenterologist to examine the stomach, esophagus and duodenum (first part of the small bowel). This is done by using a thin, flexible tube through which the lining of the above parts is viewed.
Endoscopy procedure is used to determine the causes of repeated vomiting, vomiting of blood, and difficulty in swallowing, anemia or indigestion (especially if you are over 55 years of age). It is also used to check for ulcers or early signs of cancer, Barrett’s esophagus and coeliac disease. It can also confirm the results of other tests. Endoscopy is usually done in a hospital as a day case or outpatient care. It is a very safe procedure and complications are rare. Before the examination, you should inform your doctor about any allergies you have or any medication that you are on or if you have any other health problems.
Your stomach will have to be completely empty on the day of the examination. This will enable the doctor to see the lining of the duodenum and stomach clearly. Do not eat or drink for eight hours before your test. Occasional sips of water are permissible for up to an hour and a half before the exam. The procedure is usually performed under local anesthesia, which is in the form of a throat spray. You will be awake for the procedure and may be given a sedative to relax you. The process takes 10-20 minutes to complete. You will have to lie on your side with your head bent slightly forward. The doctor will then place a mouth guard over your teeth before passing the flexible endoscope (it is as thick as a small finger) through your mouth into the esophagus. Keep your head and neck still and do not straighten it. This process will not affect your breathing. A suction tube will be used to remove the excess saliva in your mouth during the procedure. Air is pumped into the stomach through the endoscope. You might feel full or nauseated when this is done. This is done to help the doctor see the lining. The camera lens at the end of the endoscope sends images from inside to a monitor. The doctor looks at these images to examine the lining of the various organs.
Once the test is over, the endoscope is taken out quickly and easily. There is minimal discomfort but your throat might feel sore. You will be free to go home once the sedative wears off.
