Reduced protocol compliance was the most frequently identified modifiable predictive factor for adverse LOS , morbidity and readmission .
Conclusion Protocol compliance is the most frequently reported predictive factor for outcomes of ERAS programmes following laparoscopic colorectal resection .
Reduced compliance increases LOS , morbidity and readmission to hospital .
The impact of compliance with individual ERAS protocol elements is insufficiently studied , and the lack of a st and ardised framework for evaluating ERAS programmes makes it difficult to draw definite conclusions about which factors exert the greatest impact on outcome after laparoscopic colorectal resection
Objective To perform a systematic review of published literature for the factors reported to predict outcomes of enhanced recovery after surgery ( ERAS ) programmes following  laparoscopic colorectal surgery .
Background ERAS programmes and the use of laparoscopy have been widely adopted in colorectal surgery bringing short-term patient benefit .
However , there is a minority of patients that do not benefit from these strategies and their identification is not well characterised .

Two-day Hospital Stay After Laparoscopic Colorectal Surgery under an Enhanced Recovery after Surgery (ERAS) Pathway
Background The present study aims to examine the feasibility and safety of a two-day hospital stay after  laparoscopic colorectal resection ( LCR )  under an enhanced recovery after surgery ( ERAS ) pathway . Methods Between 2003 and 2010 , 882 consecutive patients undergoing LCR were analyzed . Patients were grouped and analyzed according to whether their hospital stay was 2 days ( group A ) or longer ( group B ) . Demographic , surgical , and postoperative data were compared . To identify independent predictive factors related to a short hospital stay , a multivariate analysis was also performed . Results Group A represented 10.3 % of this series ( 91 patients ) . There were no differences regarding age , gender , BMI , ASA , and previous abdominal surgeries between groups . Group A had a lower incidence of rectal cancer and anterior resections than group B ( 6.6 vs. 17.7 % [ p = 0.006 ] and 14.3 vs. 23.4 % [ p = 0.048 ] ) , respectively , and a lower mean operative time ( 170 min vs. 192 min ; p = 0.002 ) . Group A had a lower overall morbidity rate than group B ( 5.5 vs. 16.9 % ; p = 0.004 ) and a lower incidence of surgery-related complications ( 5.5 vs. 14.9 % ; p = 0.001 ) . The overall conversion rate was 10 % ( only one patient in group A required conversion ) , and the difference in conversion rate between groups was statistically significant ( 1.2 vs. 10.7 % ; p = 0.003 ) . Group A had a lower readmission rate ( 0 vs. 4.9 % ; p = 0.089 ) . Multivariate analysis showed that conversion , postoperative morbidity , and rectal prolapse were independently associated with the length of hospital stay . Conclusions A two-day hospital stay after LCR is safe and feasible under an ERAS pathway , without compromising the readmission or complication rate
