The surgical removal of small colon polyps found during computed tomography imaging of the colon, or CT colonography, is costly and unnecessary, according to a new study.
“We shouldn’t aggressively pursue sub-centimeter lesions, since the costs, risks, and inconvenience of the subsequent colonoscopy outweighs the clinical importance of these small polyps,” Dr. Perry J. Pickhardt from University of Wisconsin School of Medicine and Public Health in Madison told Reuters Health. “Over time, the few small polyps that matter will declare themselves by showing interval growth,” the researcher added.
