Optimization of perioperative care for colonic surgery: a review of the evidence.

Enhanced recovery after surgery (ERAS) care pathways are becoming increasingly common in colonic surgery. ERAS is a combination of individual strategies that have been shown to be effective in improving care. In this article, we review the evidence surrounding core components of enhanced recovery care pathways for patients undergoing open colonic surgery. We will also identify new elements that should be considered as part of ERAS strategy.
