About Colonoscopy

 

A colonoscopy is a direct visual examination of the entire large intestine or colon. The colonoscope, a specialized piece of equipment, is inserted into the rectum and maneuvered through the full length of the colon. The scope is over one meter long and about the width of a finger. Images from the scope are transmitted to a video monitor that your doctor uses to inspect the lining of the bowel. If any abnormalities are found, pictures and biopsies can be taken, as small pieces of tissue can be removed during the procedure.

Sedation is given for the procedure; therefore, you will need to arrange for someone else to drive you home.

The colonoscopy is a very safe procedure, but as with any invasive test, there are some risk. A perforation or hole in the bowel is made in less than 1 in 3000 cases. If this occurs, surgery may be required to repair the bowel. The likelihood of detecting a colon polyp or a colon cancer is much higher than the chance of a perforation.

You will need to clean out or prepare the bowel prior to the procedure. To view the complete, printable version of the preparation instructions. More information on the preparation can be found below or downloaded here.

About the Polypectomy or Polyp Removal

 

Polyps are small, mushroom shaped growths that form on the inner lining of the colon. If left alone, some polyps will continue to grow in size and can develop into colon cancer. If a polyp is seen during your colonoscopy, your doctor will use a thin wire snare to lasso and remove it. The polyp can then be retrieved and sent for microscopic evaluation. Your doctor will ask you for a follow-up at the office to discuss the results.

About the Gastroscopy

 

A gastroscopy is a direct visual examination of the upper intestinal tract (esophagus, stomach and duodenum). During your visit to Ontario Colonoscopy Clinics, your doctor may suggest a gastroscopy if you have upper intestinal symptoms such as indigestion and heart burn, or if you have signs of possible upper intestinal bleeding such as anemia (low blood count), or a positive fecal blood test. Pictures and biopsies can be taken during a gastroscopy.
