Although there is clear evidence that an Enhanced Recovery After Surgery (ERAS) program in colorectal surgery leads to significantly reduced morbidity rates and length of hospital stay (LOS), it is still unclear what modalities and levels of implementation of the program are necessary to achieve these results. The purpose of this study is to analyze the methods and results of the first year of structured implementation of a colorectal ERAS program in two surgical units of the Azienda Sanitaria Unica Regionale (ASUR) Marche in Italy. A two-center observational study on a prospectively maintained database was performed on 196 consecutive colorectal resections (excluding emergencies and American Society of Anesthesiologists class > III cases) over a 1-year period. More than 50 variables including adherence to the individual items of the ERAS program were considered. Primary outcomes were overall morbidity, major morbidity, mortality and anastomotic leakage rates; secondary outcomes were LOS, re-admission and re-operation. The results were evaluated by univariate and multivariate analyses through logistic regression. After a median follow-up of 39.5 days, we recorded complications in 72 patients (overall morbidity 36.7%), major complications in 14 patients (major morbidity 7.1%), 6 deaths (mortality 3.1%), anastomotic dehiscence in 9 cases (4.9%), mean overall LOS of 6.6 days, 10 readmissions (5.1%) and 13 reoperations (6.7%). The mean adherence rate to the items of the ERAS program was 85.4%, showing a significant dose-effect curve for overall and major morbidity rates, anastomotic leakage rates and LOS. The implementation methods of a colorectal ERAS program in this study led to a high adherence (> 80%) to the program items. High adherence had significant effects also on major morbidity and anastomotic leakage rates.
