    What Is Upper Gastrointestinal (GI) Endoscopy?

    Upper GI endoscopy is a medical procedure in which a gastroenterologist uses a 100 cm long flexible tube with a camera attached at the tip, called endoscope to see the inner part of the upper digestive system. Most of the time it is performed without sedation but for anxious or uncooperative patient it is done in light sedation. It is also called as EGD or esophagogastroduodenoscopy.

Biopsies are required for the accurate diagnosis of cancer, celiac disease or gluten sensitive enteropathy, various types of gastritis, hpylori or whippel disease or agamaglobulinemia.

    Upper GI endoscopy is also used to stop bleeding from peptic ulcer disease, varices or GAVE. It can be used to dilate the stricture related to corrosive injury or peptic ulcer or malignancy. It is also used for removing foreign body like pins dentures, coin battery form upper GI tract and hence surgery can be avoided.

    Preparation Before Endoscopy

    Inner lining of your upper GI tract during is examined by endoscopy. Therefore to clearly visualize the digestive system it is advised not to eat, drink, smoke, during the 6 hours before the procedure.

    How Upper GI Endoscopy Is Done?

    A doctor performs an upper GI endoscopy. An intravenous (IV) needle will be placed in the arm to provide an injection for sedation. In some cases, the procedure can be performed without sedation. You will be given a spray anesthetic on the back of your throat. This will numb the throat and prevent the gag reflex or discomfort due to endoscopy.

    Patient lie on one side on an examination table. The gastroenterologist gently feed the endoscope down the food pipe and then into your stomach and duodenum. The camera which is mounted on the tip of endoscope will send a video image to a monitor, allowing close examination of the lining of your upper GI tract. During the upper GI endoscopy, the doctor may…

    Take biopsy of tissue in your upper GI tract. Patient wont feel the biopsy.
    Stop any bleeding from GI tract.
    Perform other specialized procedures, such as dilating strictures.

    The procedure most often takes 2-3 minutes. Post procedure patient can perform all the normal activities. Few patients experience bloating or nausea for a short time, a sore throat for 1 to 2 days.

    What is Colonoscopy?

    This is a procedure to understand and check the condition of a patients Large Intestines. The name of the procedure is derived from the special type of tube which is inserted into the intestine to monitor its activities and to address the problem, the Colonoscope. This is a 4 foot long and flexible tube. It is one finger thick and has a camera and a light source at the top. The doctor, usually a gastroenterologist inserts the tip of the colonoscope through the patients anus and finally to the cecum.

    What is its significance?

    There is no one reason behind this answer, but several. In short, colonoscopy is done as part of a screening process and for health investigation. Colonoscopy is done for:

    • Finding determining the existence of colon cancer.
    • Blood in patient stool.
    • Pain in the abdomen.
    • Diarrhea.
    • Change in patient bowels.
    • If an X-ray discovers an abnormality.
    • If the patient has a family history of colon cancer.

    Colonoscopy can be taken more than once in a lifetime, but the number of time it is to be taken depends on the severity of problems.

    What to expect?

    Before the operation, the patient is monitored for blood pressure, rhythm of the heart and dissolved oxygen in blood. Sedatives, through an intravenous line, are then given to make the patient relaxed. Sometimes, additional sedatives are administered to reduce pain and to bring a sense of sleepiness.

    When the procedure or the operation begins, the patient is made of lie on the back or on his side. From this position, the doctor slowly advances the colonoscope up to the small intestine, and finally to the large intestine. The doctors examine the intestines walls and determine where to problem is. The operation normally takes 15 to 30 minutes, but operations of 1 hour are not uncommon either. If for some reason, the problem cannot be addressed at one sitting, the doctor may desire to opeate again at some other time.

    How it works?

    In colonoscopy, at times the doctors may need to examine an area closely. At times like these, they use an inbuilt forceps in the colonoscope itself to collect samples of the area. This sample is studied in the laboratory for infection and other complications. If there is an infection, then the doctors may order the culturing of bacteria, fungi and even certain viruses to be introduced and eliminate the threat. If bleeding is detected, it is checked by a number of methods. In some cases, polyps are detected. These are not harmful by themselves, but may become cancerous. If such is the case, these are removed easily.

    Are there complications?

    The possibilities in Colonoscopy are rare. Their chances of happening are minor especially when the operations are done by experienced doctors. At times, there may be internal bleeding, but it is nothing to worry about because the bleeding in most cases is minor and limited in area. Rarely are blood transfusions are needed.

    There are rare cases when the patient experiences a tear in the walls of the colon. However, these do not require surgery.

    In the beginning of the operation, sedatives are used. Sometimes, these sedatives cause localized irritation and severe pain the stomach. While these may occur, their chances of occurring are less than 1 percent.
