Several recent studies have shown that the Enhanced Recovery After Surgery (ERAS) protocol reduces morbidity and mortality and shortens the length of stay compared to conventional recovery strategy (pre-ERAS). The aim of this study was to evaluate the effect of the implementation of this protocol on 3-year overall survival and postoperative outcome in patients undergoing colorectal resection for cancer.

Inclusion Criteria:

• Aadult patients, who had undergone resection for colorectal cancer or a precancerous lesion and were cared for using the ERAS protocol or received conventional care (pre-ERAS).
• Informed patients

Exclusion Criteria:

• Patients presenting or developing peritoneal cancer,
• Patients having resection for palliative reasons,
• Patients those under curatorship or tutelage
• Opposed patients

The study population consisted of all consecutive adult patients, who had undergone resection for colorectal cancer or a precancerous lesion and were cared for using the ERAS protocol or received conventional care (pre-ERAS). The records of consecutive patients recorded in the hospital's electronic medical records (PMSI) between January 2005 and December 2017 were screened. Non-inclusion criteria included patients presenting or developing peritoneal cancer, patients having resection for palliative reasons, those under curatorship or tutelage.
