Gastrointestinal Endoscopy

Gastrointestinal endoscopy, enables a doctor to see the inside lining of your digestive tract. This examination is performed using an endoscope-a flexible fiberoptic tube with a tiny TV camera at the end. The camera is connected to either an eyepiece for direct viewing or a video screen that displays the images on a color TV. The endoscope not only allows diagnosis of gastrointestinal (GI) disease but treatment as well. The GI endoscopy procedure may be performed in either an outpatient or inpatient setting. Through the endoscope, a doctor can evaluate several problems, such as ulcers or muscle spasms. These concerns are not always seen on other imaging tests.

Endoscopy has several names, depending on which portion of your digestive tract your doctor seeks to inspect.

  • medical Upper GI endoscopy (EGD): This procedure enables the examination of the esophagus, stomach and the upper small bowel called duodenum.
  • medical Colonoscopy: This procedure enables the doctor to see ulcers, inflamed mucous lining of your intestine, abnormal growths and bleeding in your colon, or large bowel.

Prior to the procedure

Upper GI endoscopy (EGD): You may be given a topical anesthetic before the test to numb your throat to prevent gagging. Colonoscopy or sigmoidoscopy: Your rectum and colon should be cleaned of all fecal matter. Even a small amount of feces can reduce reliability of the test. You will change your diet prior to the test-no fibers or foods with small seeds for 5-6 days before the examination. You will drink liquids such as tea, fruit juices, and clear broth on the day prior. You may be given laxatives 12-15 hours before the test. You will be asked to drink up to 4 liters (about 4 qt) of a special cleansing solution to clean out the colon. The doctor may perform a rectal examination to detect narrowings, polyps or abnormal growth, or hidden bleeding from your lower intestine.


Upper GI endoscopy:

  • medical You will be placed on your left side and have a plastic mouthpiece placed between your teeth to keep your mouth open and make it easier to pass the tube.
  • medical Most endoscopies are done with conscious sedation - which means patients are asleep and do not feel anything.
  • medical The doctor lubricates the endoscope, passes it through the mouthpiece, then asks you to swallow it. The doctor guides the endoscope under direct visualization through your stomach into the small intestine.
  • medical Any saliva you have will be cleared using a small suction tube that is removed quickly and easily after the test.
  • medical The doctor inspects portions of the linings of your esophagus, stomach, and the upper portion of your small intestine and then reinspects them as the instrument is withdrawn.
  • medical If necessary, biopsies and removal of foreign bodies and polyps may be performed.
  • medical The procedure usually is completed within 10-15 minutes. Any surgical procedures will require several minutes.

Lower GI endoscopy:

  • medical You will be placed on your left side with your hips back, flexed beyond your abdominal wall.
  • medical The doctor lubricates the endoscope and inserts it into your anus and advances it under direct vision.
  • medical The doctor will study your colon and rectum walls and reinspect them as the endoscope is withdrawn. If necessary, surgeries may be performed.
  • medical You may feel uneasiness and abdominal pain. The procedure usually takes 15-20 minutes. Any surgeries will require additional time, depending on the type.
  • medical Most colonoscopies are done with conscious sedation. Patients are asleep and should not feel anything.

After the Endoscopy Procedure:

  • medical If you have been sedated, you will be moved to a recovery area to wake up.
  • medical Once sedation has worn off, before you are discharged from medical center, you will be given instructions and told to call your doctor if complications develop.
  • medical You should have someone there to take you home. You may feel drowsy.
  • medical At home, it would be best to have a light meal and rest for the remainder of the day.


Upper GI endoscopy (EGD): Although rare, bleeding and puncture of your esophagus or stomach walls are possible during EGD. Other complications include the following

  • medical Severe irregular heartbeat
  • medical Pulmonary aspiration - When material, either particulate (food, foreign body) or fluid (gastric contents, blood, or saliva), enters from your throat into your windpipe
  • medical Infections and fever that wax and wain
  • medical Respiratory depression, a decrease in the rate or depth of breathing, in people with severe lung diseases or liver cirrhosis
  • medical Reaction of the vagus nerve system to the sedatives

Lower GI endoscopy include the following:

  • medical Local pain
  • medical Dehydration (due to excess of laxatives and enemas for bowel preparation)
  • medical Cardiac arrhythmias
  • medical Bleeding and infection in the bowel, usually after a biopsy or removal of a polyp.
  • medical Perforation or hole in the bowel wall
  • medical Explosion of combustible gases in the colon (certain gases are produced within the bowel) during removal of polyps
  • medical Respiratory depression usually due to over sedation in people with chronic lung disease
