Gastroenterology/ GI lab

Gastroenterology is the medical specialty devoted to the study, diagnosis and treatment of disorders of the digestive system. These disorders may affect the esophagus (swallowing tube), stomach, small intestine, large intestine (colon), rectum, liver, gallbladder or pancreas.

Millions of Americans suffer from digestive diseases. These conditions can profoundly affect both the health and overall quality of life of those afflicted. Specialized physicians and staff of Kaleida Health offer expert diagnostic testing and therapeutic procedures to identify and treat these conditions such as:

  • esophageal cancer
  • colon cancer
  • inflammatory bowel disease
  • liver disease

The Gastrointestinal Lab (GI Lab) at Millard Fillmore Suburban Hospital provides a wide range of endoscopic gastroenterology and biliary services for both inpatients and outpatients. **Colonoscopy is currently the only gastrointestinal service offered to Canadian patients.**

Procedures performed include, but are not limited to:

  • 48-hour pH monitoring (BRAVO)
  • Bronchoscopy
  • Colonoscopy
  • EGD (Esophago-Gastro-Duodenoscopy)
  • ERCP (Endoscopic Retrograde Cholangiopancreatography)
  • Esophageal motility
  • Flexible sigmoidoscopy
  • Foreign body removal
Nurse and patient
A procedure in which a long flexible viewing tube (a colonoscope) is threaded up through the rectum for the purpose of inspecting the entire colon and rectum and, if there is an abnormality, taking a biopsy of it or removing it. The procedure requires a thorough bowel cleansing to assure.
Endoscopy is a broad term used to described examining the inside of the body using an lighted, flexible instrument called an endoscope. In general, an endoscope is introduced into the body through a natural opening like the mouth or anus. Although endoscopy can include examination of other organs, the most common endoscopic procedures evaluate the esophagus (swallowing tube), stomach and portions of the intestine.
Endoscopic retrograde cholangiopancreatography (ERCP)
A procedure done to diagnose and treat problems in the liver, gallbladder, bile ducts, and pancreas, including gallstones, inflammatory strictures (scars), leaks (from trauma and surgery), and cancer. ERCP combines the use of X-rays and an endoscope (a long, flexible, lighted tube). Through it, the physician can see the inside of the stomach and duodenum and inject dye into the bile ducts and pancreas so they can be seen on X-ray.

GI Waiting Room

Inspection of the rectum and lower colon using a thin lighted tube called a sigmoidoscope. Samples of tissue or cells may be collected for examination under a microscope. The flexible sigmoidoscopy instrument is a flexible tube 60 cm long that is about the thickness of a finger and it is gently inserted into the anus and advanced slowly into the rectum and then the lower colon. It is an accurate and simple method for investigating rectal bleeding, change in bowel habits, rectal symptoms such as pain, diarrhea, etc. It is also a part of colon screening and surveillance for polyps and cancer prevention.
A 48-hour test that measures and records the pH in the esophagus used to diagnose gastroesophageal reflux disease (GERD). A small capsule is inserted to monitor the pH levels in the esophagus and transmits the findings via a small radio transmitter in the capsule. The test can also be done to determine the effectiveness of medications or surgical treatment for GERD.
