Gastroenterology Tests and Procedures

  • Barium Swallow
    A barium swallow is an imaging test that uses X-rays to look at your upper gastrointestinal (GI) tract. Your upper GI tract includes the back of your mouth and throat (pharynx) and your esophagus.
  • Barium Enema
    A barium enema is an imaging test that uses X-rays to look at your lower gastrointestinal (GI) tract. Your lower GI tract includes the large intestine (colon) and rectum.
  • Upper Gastrointestinal Series

    An upper gastrointestinal series is an imaging test of your esophagus, stomach, and first part of your small intestine (duodenum). The test is done with X-rays after you swallow a special beverage. The beverage contains either contrast or a powder called barium.

  • Upper GI Endoscopy

    An upper GI endoscopy or EGD (esophagogastroduodenoscopy) is a procedure to diagnose and treat problems in your upper GI tract (gastrointestinal tract).

  • Endoscopic Retrograde Cholangiopancreatography (ERCP)

    Endoscopic retrograde cholangiopancreatography, or ERCP, is a procedure to diagnose and treat problems in the liver, gallbladder, bile ducts, and pancreas. It combines X-ray and the use of an endoscope -- a long, flexible, lighted tube.

  • Pancreas Scan

    A pancreas scan uses nuclear radiology to search for, and sometime treat, tumors in the pancreas.

  • Liver Scan

    A liver scan is an imaging test to look at your liver and see how well it is working. This test may also be called a liver-spleen scan because the doctor often looks at the spleen at the same time. The spleen is near the liver and works closely with it.

  • Liver Biopsy

    A liver biopsy is a test used to diagnose liver conditions. Tissue samples are removed from your liver and checked under a microscope for signs of damage or disease.

  • Colonoscopy

    Colonoscopy is a procedure that lets your health care provider check the inside of your entire large intestine or colon.

  • PEG Tube Placement

    A percutaneous endoscopic gastrostomy (PEG) tube is a feeding tube surgically placed through your abdomen into your stomach.

  • Sigmoidoscopy

    A sigmoidoscopy is a diagnostic test to check the lower part of your colon or large intestine (the sigmoid colon). This part of your colon is close to your rectum and anus.

  • Abdominal X-ray
    X-rays use beams of energy that pass through body tissues onto a special film and make a picture. They show pictures of your internal tissues, bones, and organs. Bone and metal show up as white on X-rays. X-rays of the belly may be done to check the area for causes of abdominal pain. It can also be done to find an object that has been swallowed or to look for a blockage or a hole in the intestine.
  • Abdominal Ultrasound

    An abdominal ultrasound is a procedure used to assess the organs and structures within the abdomen (belly). This includes the liver, gallbladder, pancreas, bile ducts, spleen, and abdominal aorta. Ultrasound allows your doctor to easily view the abdominal organs and structures from outside the body. Ultrasound may also be used to assess blood flow to abdominal organs.

  • CT Scan of the Abdomen
    CT scan is a type of imaging test. It uses X-rays and computer technology to make images or slices of the body. A CT scan can make detailed pictures of any part of the body, including the bones, muscles, fat, organs, and blood vessels. They are more detailed than regular X-rays.
  • CT Scan of the Liver and Biliary Tract

    CT scan is a type of imaging test. It uses X-rays and computer technology to make images or slices of the body. A CT scan can make detailed pictures of any part of the body, including the bones, muscles, fat, organs, and blood vessels. They are more detailed than regular X-rays.

  • CT Scan of the Pancreas

    CT scan is a type of imaging test. It uses X-rays and computer technology to make images or slices of the body. A CT scan can make detailed pictures of any part of the body, including the bones, muscles, fat, organs, and blood vessels. They are more detailed than regular X-rays.

  • Laparoscopy

    Laparoscopy uses a thin lighted tube that has a video camera. The tube is called a laparoscope. It is put into a tiny cut or incision in your belly. The video camera images can be seen on a computer screen.

  • Virtual Colonoscopy for Colorectal Cancer Screening

    Virtual colonoscopy (also known as CT colonography) is a procedure that is done to look for small polyps or other growths inside your colon. Polyps that grow on the inside lining of the colon sometimes turn into colon cancers.

  • Colectomy

    A colectomy is a surgical procedure used to treat colon diseases. These include cancer, inflammatory disease, or diverticulitis. The surgery involves removing a portion of the colon, which is part of the large intestine.

  • Proctectomy

    Proctectomy is a surgical operation to remove all or part of the rectum. Here is detailed information on this procedure.
