       BACKGROUND AND GOAL OF STUDY:
ERAS programs have been effective for reducing length of stay(LOS) and complications rate.
We review how implementation of colorectal ERAS program in a tertiary hospital affects complications, LOS and mortality.
     MATERIALS AND METHODS:
Two cohorts of patients operated on colorectal surgery (CRS) were studied:
	-A retrospective non-ERAS group: 66patients (41men/25women) between June and December 2015. 	Average age was 65.8ys (SD=13.88).
	-A prospective ERAS group: 165patients (101men/women) between January and November 2017. 	Average age was 67.54ys (SD=12.34).
We evaluate complications classified by Claviden-Dindo, LOS (with an aim of 5days LOS), readmission, and mortality.
RESULTS AND DISCUSSION:



Compliance	Laparoscopic Surgery
(%)	Oncologic Surgery
(%)	Rectal Surgery
(%)	CD I (%)	CD II (%)	CD III (%)	CD IV (%)	CD V (%)	Readmission (%)	Discharge on day 5 PO (%)	LOS (days)P50 [p25-p75]
Non- ERAS group	59,09	81,8	27,3	66,7	51,5	21,2	10,6	1,5	13,6	13,6	8 [7-12]
ERAS group	65,45	77,7	21,4	44	15,7	6,1	3,1	0,7	1,8	49,4	6 [5-10]
P value	p>0,1	p>0,1	p>0,1	0,003*	<0,001*	<0,001*	0,041*	> 0,1	< 0,001*	< 0,001*	< 0,001*
      CONCLUSIONS:
It seems ERAS program reduce complications (grade I,II,III,IV), readmission rate, LOS and increases discharge on day 5 rate.
Both groups seem comparable in laparoscopic, oncologic and rectal surgery rate.
