Colonoscopy Procedure
A colonoscopy is an endoscopic procedure used to examine the inner lining of the colon and rectum for any signs of abnormality or disease. During a colonoscopy, a flexible tube with a camera, called a colonoscope, is inserted through the anus and snaked through the entire large intestine. The colonoscope allows the doctor to view the entire colon, from the rectum all the way to the cecum. Various colonoscopy devices and attachments can be used by the gastroenterologist during the procedure to conduct biopsies, remove polyps, and treat other conditions affecting the lower gastrointestinal tract.

Colonoscopy Cameras
The camera at the tip of the colonoscope allows the physician to see the images on a video monitor in real-time as they guide the tube through the colon. Earlier generations used charge-coupled device (CCD) camera technology but modern colonoscopes now feature complementary metal-oxide-semiconductor (CMOS) image sensors. CMOS cameras provide higher-resolution images at lower power consumption compared to CCD cameras. Some of the latest Colonoscopy Devices feature 4K ultra-high definition cameras that can capture exquisite anatomical details for accurate diagnoses. Advanced imaging modalities like narrow band imaging and chromoendoscopy can help detect subtle mucosal changes not seen with standard white light endoscopy.

Colon Polyp Detection and Removal
During colonoscopy, any abnormal growths such as polyps found in the colon must be carefully examined and removed if precancerous or cancerous. Modern colonoscopy devices feature various atraumatic grasping tools, snares, and sclerosing needles to safely and effectively remove polyps of different sizes and morphological types. Advanced polypectomy techniques allow for en bloc resection of larger polyps to minimize fragmentation and ensure complete removal in a single piece for accurate pathological examination. Cap-assisted colonoscopy and multiband mucosectomy techniques increase the safety and efficacy of large polyp removal compared to conventional polypectomy.
