Colonoscopy- the process
During an examination patient is laying on his back or side. It takes 15 to 60 minutes. Adequate channels of endoscope enable sucking off the liquid which can constrain visibility, blowing the stomach with air or rinsing an ending of an endoscope. An endoscope is equipped with an bioptic channel through which any instrument like forceps or loops can be inserted. Forceps are designed to collect samples for a histopathological examination.
Collection of samples serve not only as a method to diagnose cancer, but also other diseases of the large bowel.
Colonoscopy is mostly tolerated well by patients, even so discomfort or pain is possible. For that reason the doctor can order to administer analgesic or sedative drugs which can help patient to relax and bear any discomfort.
