A diagnostic examination of the inside of the colon by inserting a long, flexible instrument called a colonoscope through the rectum. A colonoscope is a type of endoscope used specifically to examine the colon and has attachments such as lenses, a light, and a small video camera.

The examination of the interior of the large intestine by means of a flexible endoscope, a fiber-optic device commonly referred to as a colonoscope, is conducted by inserting it through the anus and maneuvering it along the length of the colon. Colonoscopy serves the purpose of investigating various symptoms, including rectal bleeding, as well as identifying physical irregularities such as inflammation, abnormal growths, and cancerous conditions. During the procedure, specialized tools can be utilized through the colonoscope to obtain tissue samples for biopsy or to extract polyps.
