       BACKGROUND AND GOAL OF STUDY: 
ERAS protocol in colorectal surgery (CRS) reduces length of hospital stay(LOS) and complication rate. 
Despite of the evidence their full implementation into daily practice meets certain difficulties. 
We review how adherence to the protocol (compliance) determines results in the implementation of the ERAS protocol in a tertiary hospital.
        MATERIALS AND METHODS: 
We examine a prospective cohort of patients operated on colorectal surgery (CRS) under ERAS program based on international guidelines: 165patients (101men/64women) (surgery: 57open, 108laparoscopic) between January and November 2017. Average age was 67.54ys (SD=12.34).
 
We evaluate if increasing compliance (<70%, >70%,>80%,>90%, 100%) have any repercussion in complications (defined using the Clavien-Dindo classification), readmission rate and LOS (aiming for discharge on day 5).
	RESULTS AND DISCUSSION:

Compliance (%)	Laparoscopic surgery (%)	Rectal Surgery (%)	CD I 
(%)	CD II (%)	CD III (%)	CD IV (%)	CD V  
(%)	Readmission
(%)	Discharge on day 5 PO (%)	LOS (days)

        CONCLUSIONS: 
When compliance increases, there is a trend in reducing complications (grade I,II,III) and LOS with more patients being discharge at day 5.

We should make bigger groups to observe stadistically significative differences.
