Senior population (> or = 70 y) represents approximately 17% of Western population and account for 2/3 of all solids cancers of which > 50% are colorectal. Their treatment would request major abdominal surgery, often not offered because of senior age or fear of prohibitive morbidity. Fast-track programs reduce postoperative morbidity and hospital stay after elective colorectal surgery. According to few studies, this approach seems to be safe and feasible in senior patients. In our institution, mortality/morbidity rates were 0% and 37% after elective colorectal surgery in senior patients with standard care, with a median hospital stay of 13 days. Elective colorectal surgery should be offered to senior patients. However the relative high morbidity rate with standard care prompts us to initiate a specifically designed fast-track protocol in senior patients.
