Techniques and Tips for Lower Endoscopy
Colonoscopy has become the method of choice for visualization of the entire colonic mucosa and distal small bowel. The indications for colonoscopy include screening and surveillance as well as for the diagnosis and treatment of many colonic disorders. The majority of colonoscopies are performed for screening or surveillance of colorectal cancer, which occurs in approximately 140,000 cases per year in the USA. Screening endoscopy with polypectomy has lead to a decreased colorectal cancer incidence over the years along with decreased mortality.
