Colonoscopy or coloscopy is the endoscopic examination of the big bowel and the distal part of the small bowel with a CCD digital camera or a fiber optic digicam on a flexible tube handed through the anus. It can provide a visible diagnosis (e.G., ulceration, polyps) and presents the opportunity for biopsy or removal of suspected colorectal cancer lesions.

Colonoscopy can get rid of polyps smaller than one millimeter. Once polyps are removed, they may be studied with the useful resource of a microscope to decide if they're precancerous or no longer. It can absorb to fifteen years for a polyp to turn cancerous.

Colonoscopy is much like sigmoidoscopy—the difference being associated with which components of the colon each can examine. A colonoscopy permits an exam of the whole colon (1200–1500 mm in duration). A sigmoidoscopy allows an examination of the distal component (about 600 mm) of the colon, which may be enough due to the fact blessings to most cancers survival of colonoscopy had been restrained to the detection of lesions inside the distal part of the colon.

 

A sigmoidoscopy is often used as a screening system for a full colonoscopy, frequently done in conjunction with a fecal occult blood take a look at (FOBT). About five% of these screened patients are mentioned colonoscopy.

Virtual colonoscopy, which makes use of 2D and 3-D imagery reconstructed from computed tomography (CT) scans or from nuclear magnetic resonance (MR) scans, is also viable, as a very non-invasive medical check. Virtual colonoscopy does now not allow therapeutic maneuvers along with polyp and tumour removal or biopsy, nor visualization of lesions smaller than 5 millimeters; if a increase or polyp is detected the use of CT colonography, it might require removal at some stage in a fashionable colonoscopy. Surgeons have used the time period pouchoscopy to refer to a colonoscopy of the ileo-anal pouch. standard optical colonoscopy has been a successfully publishing quality Research article from many years and looking forward to frame up eminent, outstanding issues with best quality research articles in this year.
