  • Endoscopy

    A doctor uses an endoscope to view a patient's internal organs.

    Detailed Information:
    The most accurate way to detect ulcers, stomach cancer, and H pylori is endoscopy with biopsy. However, this procedure is both invasive and expensive. Endoscopy is the general term for the examination of the inside of the body with an endoscope. An endoscope is a thin, flexible tube with a camera at its tip that a doctor inserts into the body to view the internal organs. Most endoscopes have a light that illuminates the area that is being examined. A viewer reflects the image back up the scope, and a lens enlarges the image. The doctor can view the image on a monitor. Some endoscopes have tiny compartments in which instruments pass through to collect samples of tissue for a biopsy or operation.

    Doctors use the endoscope most frequently to view the gastrointestinal tract, such as the stomach, or the uppermost part of the small intestine. The doctor inserts the endoscope into the patient’s mouth to view these body parts. When the doctor examines the rectum or lower colon, the procedure is called proctoscopy or sigmoidoscopy, and the endoscope is inserted into the anus. To examine the colon, doctors use a longer endoscope, inserted through the anus; this process is called a colonoscopy.

    The sinuses, lungs, abdomen, pelvis, bladder, and joints can also be viewed using an endoscope. In laparoscopy, doctors use the endoscope to directly view the abdominal organs. After using a local anesthetic, that numbs the skin and underlying tissue, one or more small incisions are made in the skin of the abdomen. The endoscope is passed into the abdominal space to clearly view the organs or help perform surgery.

    In laryngoscopy, the doctor uses a thin endoscope to look farther down the throat to view the larynx and vocal cords. A bronchoscope is used to view the large airways of the lungs. Using this instrument, the doctor can view tumors or areas of infection, as well as take biopsies of abnormal lung tissue. The endoscope now is increasingly being used in surgery. For example, surgeons can remove the gallbladder using an endoscope.
