Enhanced Recovery After Surgery (ERAS) is a protocol of perioperative care that aims at improving recovery, shortening of hospital stay and decrease in perioperative complications. First study analyzed the relation between compliance to ERAS protocol and clinical outcomes in patients undergoing colorectal surgery. Gradual increase of compliance to ERAS protocol caused significant reduction of complications rate, and the mean length of hospitalization decreased from 5 days to 3 days. Acquired results allowed to conclude that implementation of ERAS protocol is a gradual process and compliance to ERAS protocol can steadily increase what will positively effect on clinical outcomes.The 2nd second study assessed feasibility of ERAS implementation in elderly patients. Clinical outcomes of patients >65 and ≤ 65 years were compared. Complications rate, length of hospitalization were similar between two groups and no negative impact on the rate of readmissions was noticed. Conclusion of the study was that implementation of ERAS protocol in elective colorectal surgery is possible irrespective of the age of surgical patients and is safe even in elderly patients. Third questionnaire study analyzed trends in perioperative care in elective colorectal surgery among 165 general surgery consultants from malopolska voivodeship. The level of acceptance of many crucial elements of perioperative care (laparoscopy, early mobilization etc.) did not exceed 10-15%. Poor acceptation of ERAS elements in colorectal surgery creates a barrier to optimization of patient`s care and requires change in clinical practice.
