• Patient EducationAt the Gastrointestinal Procedures Center of Excellence at Memorial University Medical Center, we believe that informed patients make better medical choices and have better overall health. We encourage you and your loved ones to talk with your doctor about any questions or concerns you have before your procedure. The information below may also be helpful, but please note that this information should not replace any instructions from your physician.

    Barrett's Esophagus

    This condition occurs when cells in the lining of the esophagus morph into abnormal cells.  


    This procedure lets your doctor see directly inside your entire colon using a flexible tube. It can detect intestinal problems such as bleeding or early signs of colorectal cancer.  

    Colon Cancer
    Colorectal Cancer

    Colorectal cancer occurs when cells grow and divide uncontrollably in the colon or rectum. Left untreated, it can spread to other parts of the body.

    Digestive System

    Diverticuli are herniations in the muscular layer of the colon that produce small, saclike swellings. Diverticulitis occurs when diverticuli become inflamed and infected.  

    • Watch a video about diverticulitis causes, symptoms, and treatments.  
    EGD (Upper Endoscopy)

    This procedure is done to look at part of the digestive system. It helps diagnose conditions such as acid reflux and ulcers.

    Endoscopic Retrograde Cholangiopancreatography

    This procedure, also called ERCP, allows the doctor to diagnose and treat problems in the liver, gallbladder, bile ducts, pancreas, and pancreatic duct.

    Endoscopic Ultrasound

    Endoscopic ultrasonography (EUS) allows your doctor to examine your esophageal and stomach linings as well as the walls of your upper and lower gastrointestinal tract.

    • EUS information from the American Society for Gastrointestinal Endoscopy.
    Eosinophilic Esophagitis

    This is an allergic condition that occurs in the esophagus.

    Esophageal Dilation

    This procedure allows your doctor to dilate or stretch a narrowed area of your esophagus.

    Gastroesophageal Reflux Disease (GERD)/Heartburn

    This digestive disorder occurs when gastric acid flows from the stomach into the esophagus.


    These are veins in and around the anus and lower rectum that have become swollen due to stretching under pressure.


    This procedure allows a doctor to examine the lower portion of your colon using a thin tube. It may be used to help diagnose certain intestinal problems that can cause symptoms such as constipation, diarrhea, or abdominal pain. It may also detect abnormal growths.
