Gastroenterology at Danbury Hospital provides colonoscopies as a screening, testing, and prevention method. Colonoscopies are a highly effective and low-risk method of screening for colorectal polyps and other gastrointestinal conditions.

More accurate than an x-ray or exam, colonoscopies allow doctors to detect and remove most polyps without abdominal surgery, a major step towards the prevention of colon cancer.

Most colonoscopies are done on an outpatient basis, with minimal inconvenience and discomfort. This is a very common procedure, and the gastroenterologists at Danbury Hospital have safely performed thousands.

What to Expect

A colonoscopy involves the insertion of a long, flexible tubular instrument so that the doctor can visually examine the full lining of the colon and rectum. This makes it possible to:

  • Diagnose colon and rectum problems
  • Check unexplained abdominal symptoms
  • Examine patients with unexplained rectal bleeding or blood in the stool
  • Check inflammatory bowel disease (colitis)
  • Perform biopsies
  • Verify and remove colon polyps
  • Verify tumors found during a barium enema exam
  • Monitor patients with a past history of colon polyps or cancer

Colonoscopies are useful procedures that are done for a range of reasons. Getting a colonoscopy does not necessarily mean that cancer is known or even suspected.

Preparing for a Colonoscopy

Before a colonoscopy, it’s necessary to clear all residues from the bowel. This is done in two ways. First, patients preparing for a colonoscopy will be asked to eat no solid food and drink only clear liquids on the day before the procedure. They should also avoid alcohol and dairy products.

In addition, patients will need to undergo some type of bowel evacuation. This can be done in several ways, depending on the patient’s preference and medical history.
