Colonoscopy is an examination of the rectum, colon, and lower part of the small intestine. The examination is carried out using a coloscope, a flexible hose which is inserted into the rectum. The inside of the bowel is inspected and images are transferred to a monitor.

It is important that the bowel is empty during the examination.

X-ray should be available during the examination to simplify positioning of the instrument.

During a colonoscopy, the following can be performed:

  • Biopsy
  • Polyp removal
  • Unblocking of cramped parts
  • Coagulation of bleeding


  • Suspicion of cancer or inflammation in the colon or lower part of the small intestine
  • Obstruction (constricted anastomoses)


  • Confirmation and biopsy of pathological changes.
