Endoscopy


Endoscopy is a technique used by gastroenterologists to view inside the body’s upper and lower gastrointestinal tract with an endoscope. The experts at the Center for Digestive Health at St. Joseph’s offer several advanced endoscopy services and procedures using state of the art technology:

Colonoscopy – A procedure that allows your physician to examine the inside of your colon and rectum.

  • A colonoscopy may be required to find the cause of certain symptoms or abnormal lab tests or other imaging, including the following:
    • Abdominal pain, changes in bowel movements, or weight loss
    • Abnormal changes (polyps) found on sigmoidoscopy or x-ray tests (CT scan or barium enema)
    • Anemia due to low iron (usually when no other cause has been found)
    • Blood in the stool, or black, tarry stools
    • Follow-up of a past finding, such as polyps or colon cancer
    • Inflammatory bowel disease (ulcerative colitis and Crohn disease)
    • A colonoscopy may be used as a screening for colorectal cancer – Both men and women should have a colon cancer screening starting at age 50, unless otherwise directed by their physician.
  • Therapeutic Use:
  • Endoscopic mucosal resection (EMR) – A procedure to remove abnormal tissues from the digestive tract.
  • Endoscopic submucosal dissection (ESD) – An advanced procedure to remove tumors that have not yet entered into the muscle layer.
  • Luminal stenting – A device placed within the gastrointestinal tract to keep the structure open.

Endoscopic Retrograde Cholangiopancreatography (ERCP) – A complex procedure that helps doctors diagnose problems in the ducts of the pancreas, gall bladder, or liver. In this procedure, an endoscope is passed down the throat, through the stomach, and into the first part of the small intestine. The doctor then guides a tiny tube at the end of the endoscope into the common bile duct, which connects the intestine with the pancreas. A small amount of contrast material (dye) is pushed in, and x-rays are taken. The dye helps outline the bile ducts and pancreatic duct. The x-rays can show whether the ducts are narrowed or blocked, which could be caused by a gallstone or a cancer. The doctor doing this test can also put a small brush through the tube to take out some cells for biopsy.

Endoscopic ultrasound – A small transducer is placed on the tip of an endoscope and used to take a picture of abnormal cells and see how they may have spread. A transducer uses sound waves to detect echoes and convert this information into an image. An endoscopic ultrasound provides a better image than a standard ultrasound because of the shorter distance the sound waves have to travel. This technique can also be used to get a tissue sample for further evaluation.

Upper Endoscopy (EGD) – a procedure that allows a physician to examine the lining of the esophagus, stomach and duodenum.

  • An EGD may be required to find the cause of certain symptoms or abnormal lab tests, including the following:
  • Upper GI endoscopy can help find the cause of unexplained symptoms, such as persistent heartburn
  • bleeding
  • nausea and vomiting
  • pain
  • problems swallowing
  • unexplained weight loss
  • anemia
  • nutritional deficiencies
  • An EGD can identify many different diseases; sometimes a biopsy is taken.
    • anemia
    • gastroesophageal reflux disease
    • ulcers
    • cancer
    • inflammation, or swelling
    • precancerous abnormalities
    • celiac disease
  • During upper GI endoscopy, a doctor obtains biopsies by passing an instrument through the endoscope to obtain a small piece of tissue. Biopsies are needed to diagnose conditions such as
    • cancer
    • celiac disease
    • gastritis
  • Doctors also use EGD to
    • Treat conditions such as bleeding ulcers.
    • Dilate strictures with a small balloon passed through the endoscope.
    • Remove objects, including food that may be stuck in the upper GI tract.
  • Therapeutic Uses for EGD:
    • Endoscopic mucosal resection (EMR) – A procedure to remove abnormal tissues from the digestive tract.
    • Endoscopic submucosal dissection (ESD) – An advanced procedure to remove tumors that have not yet entered into the muscle layer.
    • Dilation – A procedure that dilates, or enlarges, an area allowing easier swallowing.
    • Radio Frequency Ablation (RFA) – A procedure to delivered radio waves in a precise and controlled manner to burn and destroy abnormal tissue.
    • Optical coherence tomography (OCT) – A high-resolution, cross-sectional imaging technique, similar to an ultrasound, except that OCT uses light to create images of tissue in real time rather than taking a biopsy allowing interventional procedures to be done at the same time.
    • Confocal Endomicroscopy – A powerful, miniaturized microscope used to see internal structures in precise detail allowing physicians to identify abnormal cells in real time.
    • Cryotherapy - A procedure to freeze and destroy abnormal tissue.
    • Luminal stenting – A device placed within the gastrointestinal tract to keep the structure open.

Enteroscopy – A small flexible instrument used to examine the small bowel to evaluate gastrointestinal bleeding.

Manometry – The measurement of muscle pressure within either the esophagus or anal sphincter.

Stenting – A device placed to increase an opening in any of the following areas:

  • colon
  • esophageal
  • small bowel
  • pancreatico-biliary

Video capsule endoscopy – A video capsule containing tiny cameras, a light bulb, battery and radio transmitter is swallowed. As it travels through the esophagus, stomach and small intestine it take photographs rapidly and transmits the images to a small receiver worn by the patient. After about 8 hours the photographs are downloaded from the receiver into a computer so they can be reviewed by a physician. The capsule itself is passed by the patient and flushed.
