Colorectal cancer is the third most common cancer in men, after prostate and lung cancer. It represents 11.2% of all new cases of male cancer. In women, this cancer is the second most common after breast cancer (11.3% of all new cases of female cancer).

Colorectal cancer is the second leading cause of cancer death in France. It accounts for nearly 12% of all cancer deaths, especially among those 65 and over. However, mortality has declined steadily since 1980.

Access to screening for colorectal cancer and resection of precancerous lesions partly explains this decline. All sexes combined, it is estimated that about one in five colorectal cancer is diagnosed at a limited local stage. The treatment is then less heavy and gives better results.

With the development of Enhanced Recovery After Surgery (ERAS) protocols and their extension to rectal excision, it becomes imperative to be able to collect operative data from these patients on a perennial basis for the purpose of evaluating our results. Finally, the evaluations resulting from this database could have prognostic value and ultimately allow us to adapt the surgical management of the patient according to the results.
