Colorectal Neoplasms: Screening and Surveillance After Polypectomy
Screening for colorectal cancer in average-risk individuals begins at age 50 and may continue to age 75. Screening intervals vary according to personal and family history. A number of screening modalities now exist, though colonoscopy remains the gold standard as it is both diagnostic and therapeutic. Attention to quality improvement guidelines can enhance the efficacy of colonoscopy screening. Surveillance after colonoscopic polypectomy is dependent on polyp type, size, and number. Management considerations for occult carcinomas noted after polypectomy are based on histology and polyp morphology (sessile vs. pedunculated).
