Eighty-Year-Old Patient With History of a Twelve Millimeter Adenomatous Polyp Resected at Age of Seventy-Five Years

An 80-year-old man who had resection of 12-mm adenoma 5 years earlier during a screening colonoscopy is now referred for surveillance colonoscopy. Four years ago, he had a myocardial infarction and now has mild congestive heart failure, controlled with medications. Other problems include diabetes (diet-controlled) and hypertension. He has early stage prostate cancer, diagnosed 2 years earlier. He elected to have no treatment. He is vigorous and walks 2 miles every day. His physical examination is unremarkable. His lungs are clear to auscultation, and he has no jugular venous distention or peripheral edema. Should he undergo surveillance colonoscopy?
