Endoscopy is a procedure that allows viewing the inside of an organ such as the stomach and bowel. A thin flexible tube with a camera attached is inserted in a natural opening (mouth, anus) to reach the organ to examine. The images are transmitted on a screen.

Endoscopy is used to diagnose inflammations, tumours, polyps and cancers. The procedure can also be used to remove a small tumour or perform a biopsy. There are several types of endoscopic procedures, each with a specific name.

  • A colon examination is a colonoscopy.
  • The esophagus or stomach examination is a gastroscopy.

Endoscopy procedures are provided by Perioperative Services.
