GI Lab/Gastroentrology

The state-of-the-art Gastrointestinal Laboratory (GI Lab) offers superior gastrointestinal care for endoscopic and gastrointestinal-related procedures. The GI Lab provides a wide range of diagnostic and therapeutic procedures for digestive disorders, including ulcers, gastroesophageal reflux disease (GERD), colon cancer, and inflammatory bowel disease (Crohn's and Ulcerative Colitis). 

Procedures performed in the GI Lab include, but are not limited to:

Colonoscopy
An endoscope is passed through the rectum and into the large intestine so that the physician can exam the colon and large intestine. Sometimes, small samples of tissue (approximately the size of the tip of a pencil or a hang nail) are taken for a pathologist to evaluate under a microscope. The colonoscopy is usually done under general anesthesia. In order to visualize the bowel during the colonoscopy, a bowel cleanout will need to be done prior to the procedure. Patients will be given explicit instructions on preparing for their colonoscopy. Due to the sedation used, patients cannot drive themselves home from the procedure and should remain at home for the rest of the day.  Normal activities may resume the following day.
Endoscopic Retrograde Cholangiopancreatography (ERCP)
ERCP is performed to diagnose and treat problems with the liver, gallbladder, bile ducts, and pancreas such as 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) to access the organ in question.
Endoscopic Ultrasound (EUS)
This procedure joins the medical technique of endoscopy with the high frequency sound-wave technology known as ultrasound. This state-of-the-art combination allows the physician to "microscopically" examine tissue not only within the digestive tract but surrounding it as well.
Liver Biopsy
A liver biopsy means that a sample of liver tissue is taken, which is then evaluated under a microscope by a pathologist. The procedure is done under either general anesthesia or conscious sedation. Patients may experience mild pain at the biopsy site for 24 hours, so quiet recovery at home is important. Due to the use of sedation, patients will need a ride home after the procedure.
Upper Endoscopy
An endoscope is passed through the mouth, into the stomach and to the beginning of the small intestine. Small samples of tissue (approximately the size of the tip of a pencil or hang nail) are taken, if necessary, so that they can be examined by a pathologist. This procedure is usually done under general anesthesia. Eating and drinking restrictions will be given to the patient by the nurse prior to the procedure. Patients may experience a mild sore throat for 24 hours post-procedure that can usually be relieved by consuming cold liquids and/or popsicles. Patients may also be drowsy as an effect of the general anesthesia and should plan on a quiet recovery at home for the remainder of the day. Normal activities may resume the following day.

In addition, the GI Lab provides medical information on the following:

  • Constipation
  • Gastroesophageal reflux
  • High fiber diet
  • Irritable Bowel Syndrome/Function
  • Abdominal pain
  • Low residue diet
