Rationale
Colonoscopy is the recommended method of surveillance after the removal of adenomatous polyps because it has been shown to significantly reduce subsequent Colorectal Cancer incidence. The timing of follow-up colonoscopy should be tailored to the number, size, and pathologic findings of the adenomatous polyps removed. The time interval for the development of malignant changes in adenomatous polyps is estimated at 5 to 25 years (ICSI, 2006). A randomized controlled trial of 699 patients showed that after newly diagnosed adenomatous polyps have been removed by colonoscopy, follow-up colonoscopy at 3 years detects important colonic lesions as effectively as follow-up colonoscopy at both 1 and 3 years (ICSI, 2006). Performing colonoscopy too often not only increases patients’ exposure to procedural harm, but also drains limited resources that could be more effectively used to adequately screen those in need. Recent evidence from 4 surveys indicated that postpolypectomy surveillance colonoscopy in the United States is frequently performed at intervals that are shorter than those recommended in guidelines (Rex et al, 2006). Some endoscopists in these studies performed colonoscopy in patients with only small hyperplastic polyps or a single tubular adenoma at 1 year. These surveys underscore the importance of measuring intervals between examinations in continuous quality improvement programs.
Clinical Recommendation Statement
Patients with 1 to 2 small (1 cm) tubular adenomas with only low-grade dysplasia should undergo follow-up colonoscopy no earlier than 5 years later. Patients with advanced adenomatous lesions or >3 adenomas should have repeat colonoscopy in 3 years as long as all visualized polyps were completely removed, the colonoscopy was completed up to the cecum, and the colonic preparation was adequate. A shorter interval of follow-up is recommended in those patients with numerous adenomatous (>10) polyps and in those in whom the colonoscopy was incomplete or the preparation was inadequate. After a surveillance colonoscopy has normal results, repeat examinations should be done at 5-year intervals. Patients with large, sessile adenomatous lesions removed in a piecemeal fashion should have a repeat examination within 2 to 6 months to exclude and remove and remnant polypoid tissue (Davila et al, 2006).
