Maximizing the Effectiveness of Colonoscopy in the Prevention of Colorectal Cancer

Colonoscopy is a proven screening test for colorectal cancer; maximizing its effectiveness is the best way to decrease interval colorectal cancer. The adenoma detection rate can be improved by monitoring physician detection rates. Assistive devices and innovative endoscopic equipment may also decrease adenoma miss rates. Complete polypectomy of adenomatous lesions and recommending the proper date for the next examination are important considerations. Advanced polypectomy techniques, including endoscopic mucosal resection and endoscopic submucosal dissection, have a clear role in the nonsurgical management of large laterally spreading adenomatous polyps that previously would have required surgical resection.
