Gastroenterology Procedures

Comprehensive Diagnosis for GI Disorders

Rochester Regional Health offers many state-of-the-art endoscopy procedures to help diagnose and treat disorders of the digestive tract, esophagus, colon, and lungs. A small instrument called an endoscope is used to see the inside of the digestive tract.

Common health conditions diagnosed from endoscopic procedures include:

  • Acid reflux disease
  • Celiac disease
  • Colorectal cancer
  • Crohn's disease
  • Diverticulitis
  • Inflammatory bowel disease
  • Irritable bowel syndrome

Common Procedures

Our expert physicians work together to provide advanced treatment options for conditions affecting the digestive system, including the stomach, intestines, colon, pancreas, liver, and esophagus. Some of our most common procedures are explained in detail below.

Upper Endoscopy

An upper endoscopy is a diagnostic procedure that explores the inner structures of the uppermost digestive system to pinpoint the cause of unexplained symptoms like:

  • Vomiting
  • Abdominal pain
  • Difficulties swallowing
  • Gastrointestinal bleeding

The test may also be useful for accessing the damage in your esophagus caused by acid reflux and gastroesophageal disease (GERD).


A colonoscopy is both a diagnostic and preventive procedure that can identify changes in your large intestine, colon, and your rectum. These changes can indicate the presence of disease that affects your gastrointestinal health, including colon cancer.

Endoscopic Retrograde Cholangiopancreatography (ERCP)

In an ERCP procedure a dye is injected into your bile and pancreatic ducts using a flexible, video endoscope. Then, X-rays are taken to outline the bile ducts and pancreas. An open channel in the scope allows other instruments to be passed through it to perform biopsies, inject solutions, make incisions, or place stents. ERCP helps in diagnosing and treating conditions of the bile ducts, gallbladder, and pancreas.

ERCP may be used for:

  • Gallstones, which are trapped in the main bile duct
  • Blockage of the bile duct
  • To evaluate yellow jaundice, which turns the urine dark and your skin yellow
  • Cancer of the bile ducts or pancreas
  • Pancreatitis, which is inflammation of the pancreas
  • Infections of the bile ducts
  • Leaks of the bile duct or pancreatic duct

Endoscopic Ultrasound (EUS)

An endoscopic ultrasound (EUS) is a minimally invasive test to further evaluate the digestive tract on a more advanced level. An EUS combines two diagnostic tools:

  • Endoscope: A flexible, tube that is used to further examine organs that are not inside of the digestive tract, as well as lesions that are not visible to the naked eye via regular endoscopy.
  • Ultrasound: Uses sound waves to generate detailed images of your body on a monitor

EUS can be used to detect tumors, biopsy tumors, and stage tumors in the gastrointestinal (GI) tract. EUS can be used to take tissue and fluid samples to provide a diagnosis. Or, evaluate abnormal findings from imaging tests, such as cysts of the pancreas.

EUS can also help:

  • Assess how deeply a tumor penetrates your abdominal wall in esophageal, gastric, rectal, pancreatic and lung cancers
  • Evaluate abnormal findings from imaging tests, such as cysts of the pancreas
  • Guide drainage of pseudocysts and other abnormal collections of fluid in the abdomen

EUS is performed under sedation on an outpatient basis on our Unity and Rochester General Hospital campuses and is well-tolerated by most people.

Video Capsule Endoscopy

Video capsule endoscopy (also known as a small bowel capsule endoscopy) is a procedure that uses a tiny wireless camera inside a capsule to take pictures of your digestive tract. The capsule endoscopy is a vitamin-sized capsule and contains a camera.

Video capsule endoscopy provides pictures inside your small intestine — an area that isn't easily reached with more-traditional endoscopy procedures. VCE examines the intestinal track not easily reached by Colonoscopy or Upper Endoscopy. Unlike a traditional endoscope, the capsule can access the entire length of your small intestine.  However, the capsule is not able to treat the conditions it detects.

Video capsule endoscopy may be recommended to:

  • Find the cause of gastrointestinal bleeding. The most common reason for doing capsule endoscopy is to explore unexplained bleeding in the small intestine.
  • Diagnose inflammatory bowel diseases, such as Crohn's disease. Capsule endoscopy can reveal areas of inflammation in the small intestine.
  • Diagnose cancer. Capsule endoscopy can show tumors in the small intestine or other parts of the digestive tract.
Video capsule endoscopy is performed a Unity, Wilson Health Center, and Clifton Spring Campuses.
