What Is Advanced Endoscopy?

Advanced endoscopy enhances traditional endoscopic procedures (in which a long thin tube with a camera is inserted in the body to allow doctors to assess and diagnose) by utilizing additional technology to allow more specialized diagnostic tests and treatments. The Digestive Disease Center At Roger Williams Medical Center has physician experts who offer advanced endoscopic procedures. These specialists perform minimally invasive procedures, with no incision, to diagnose and treat disorders of the esophagus, stomach gallbladder liver, pancreas, and colon.

What Are the Advantages of Advanced Endoscopy?

Advanced endoscopy offers significant clinical advantages in patient care. These include:

  • Early detection of gastrointestinal disorders, including cancers of the esophagus, stomach, liver and pancreas.
  • Diagnosing and staging gastrointestinal tumors.
  • Minimally invasive procedures to remove pre-cancerous polyps.

 What Advanced Endoscopy Procedures Do We Offer?

 The Roger Wiliams Digestive Disease Center offers a wide array of advanced endoscopic diagnostics and clinical interventions. These include the following:

 Barrx™ radiofrequency ablation system: a non-invasive endoscopy that uses radiofrequency (heat) to treat abnormalities in the upper GI tract. A Barrx radiofrequency ablates precancerous cells before they can turn into cancer cells, leaving healthy tissue behind. This treatment is often used to treat Barrett’s esophagus during an upper endoscopy. Barrett’s esophagus increases the risk of esophageal cancer, so diagnosing and treating it early is the key to beating cancer before it develops.

  • Endoluminal stenting: During this procedure, your doctor will place a stent in your esophagus, small bowel or colon to relieve an obstruction in your GI tract. This treatment can be used for cancerous or non-cancerous blockages in your GI tract.
  • Endoscopic retrograde cholangiopancreatography (ERCP) Using an endoscope, the doctor does this test evaluate the pancreatic or bile duct - the small tubes that carry digestive juices from your liver and pancreas to your intestines.This test can be used to remove stones from your gallbladder and bile ducts, as well as to diagnose and treat obstructive jaundice, pancreatic cancer, biliary strictures, and leakage and drainage of pancreatic cysts or pseudocysts.
  • Endoscopic retrograde cholangiopancreatography (ERCP): This is used for complex extraction of kidney stones and evaluation of bile duct blocakges
  • Upper endoscopic ultrasound (EGD/EUS) This test allows the doctor to examine the stomach lining and the walls of the upper GI tract, including stomach, esophagus, and duodenum (the first section of your small intestine). It can also be used to examine lungs, gallbladder and pancreas. This test can determine whether certain cancers have spread to lymph nodes or blood vessels. Most importantly, samples can be obtained under EUS guidance with fine needle aspiration for diagnosis. Your doctor may use it to diagnose cancers, conditions and diseases including:


    • Abdominal pain
    • Abnormal weight loss
    • Lumps, lesions, and cysts
    • Certain digestive system and respiratory system cancers
    • Gallbladder diseases
    • Pancreas diseases
    • Bile duct diseases
