[Endoscopic monitoring after excision of colorectal cancer].

The aim of coloscopy after radical colorectal surgery for cancer is: to find another tumor or a local recurrence. The policy must be adapted. When the preoperative approach is inadequate, coloscopy must performed between 3 to 6 months. After complete polypectomy, a coloscopic survey significantly reduces mortality and the incidence of colorectal cancer and has to be done at 3 years and then every 5 years. Data are not sufficient to establish a strategy for the local recurrence survey. The patients aged 75 and over, do not necessarily require repeated coloscopy.
