[Endoscopic methods of treatment of precancerous lesions of the colon].
The endoscopic method--colonoscope, has become the tool of choice for diagnosing many colonic disorders, including the acute and chronic inflammatory bowel disease, lower gastrointestinal bleeding, benign and malignant tumors, and various others abnormalities appearing on the radiographs. The colonoscope is also useful and become the main confirmation method in screening for and monitoring colonic cancer. In the same time, colonoscopy offers numerous therapeutic options. The colonic polyps, well-known colonic precancerous lesions, with incidence ranges from 7 to 50%, can be removed completely during the colonoscopy, with a snare or biopsy forceps (polypectomy). Early cancers limited to the mucosal layer (intraepithelial cancer or carcinoma in situ) can be treated endoscopically too (mucosectomy), as well as various gastrointestinal bleeding (with sclerotherapy, electrocoagulation, APC, laser-fotocoagulation), inflammatory and postsurgical strictures (endoscopic dilation), and foreign bodies in the rectum and sigma (endoscopic extraction).
