E.R.A.S. pathway in colorectal surgery in elderly: Our experience: A retrospective cohort study.

AIM: Numerous geriatric patients develop colorectal disease. Elderly patients are often considered high-risk surgical candidates. Enhanced recovery after surgery (E.R.A.S.) has been proven to be beneficial for patients. The aim of the study was to evaluate the results of an ERAS protocol in older patients that underwent colorectal surgery compared to younger patients.

METHOD: In the period between January 2010 to December 2015 a total of 589 patients underwent elective colorectal surgical interventions treated within the E.R.A.S pathway: 211 patients younger than 65 years, 175 patients aged from 66 years to 75 years, and 203 patients older than 75 years. End point of interest were postoperative complications, 90-day mortality, length of hospital stay and readmission within 30 days.

RESULTS: Significant differences between the three groups were observed for comorbidities (p:0.001); in particular older patients had significantly more diabetes, renal, cardiac, and respiratory diseases, ASA (p < 0.001), presence of malignancy (p < 0.001). However there were not differences between the groups in surgical procedures (p = 0.095), operative time (p = 0.823), anastomotic leakage (p = 0.960), hospital stay (p = 0.081), readmission rate (p = 0.904), 90-days mortality (p = 0.183) and morbidity (p = 0.973) in accordance with Clavien-Dindo classification. Multivariate logistic regression analysis showed that advanced age in E.R.A.S. pathway is not a predictive factor of morbidity, readmission within 30 days and 90-day mortality.

CONCLUSION: There was no significant difference in morbidity, 90-day mortality, length of stay or readmission rate in patients aged over 75 years compared with younger patients. Old age does not represent a contraindication to the implementation of the E.R.A.S protocol in patients that underwent colorectal surgery. WHAT DOES THIS PAPER ADD TO THE EXISTING LITERATURE?: In the literature there are not many studies that address the impact of older age in the treatment of colorectal disease in an ERAS program. The aging of the population raises new questions in the management of the colorectal surgery in the elderly. ERAS pathway has been proven to be beneficial for patients, which results in a reduction of postoperative morbidity. Compared to what is reported in the literature this study confirms that ERAS program in colorectal surgery can be applied in older patients with no significant difference in morbidity, 90-day mortality, length of stay or readmission rate compared with younger.
