    Anoscopy: An anoscopy is an examination using a small, rigid, tubular instrument called an anoscope (also called an anal speculum). This is inserted a few inches into to the anus in order to evaluate problems of the anal canal. Anoscopy is used to diagnose hemorrhoids, anal fissures (tears in the lining of the anus), and some cancers.




    Esophagogastroduodenoscopy (EGD)
    An EGD is performed to evaluate, and sometimes to treat, such symptoms relating to the upper gastrointestinal tract as:

    * pain in the chest or upper abdomen
    * nausea or vomiting
    * gastroesophageal reflux disease (GERD)
    * difficulty swallowing (dysphagia)
    * bleeding from the upper intestinal tract and related anemias

    In addition, an EGD may be performed to confirm abnormalities indicated by such other diagnostic procedures as an upper gastrointestinal (upper GI) x-ray series or a CT scan. It may be used to treat certain conditions, such as an area of narrowing (stricture) or bleeding in the upper gastrointestinal tract.






    Colonoscopy
    Colonoscopy enables visual inspection of the entire large bowel from the distal rectum to the cecum (see the images below). The procedure is a safe and effective means of evaluating the large bowel. The technology for colonoscopy has evolved to provide a very clear image of the mucosa through a video camera attached to the end of the scope. The camera connects to a computer, which can store and print color images selected during the procedure.
