Enhanced recovery after rectal surgery: what we have learned so far

Enhanced recovery after surgery (ERAS) protocols are gradually becoming the gold standard in the perioperative management of rectal patients. It is a multimodal and multidisciplinary approach that has the great merit to involve and empower the patient and bring him or her back to the centre of the strategy of care. If applied correctly, ERAS can improve the postoperative recovery, reduce the rate of complications and reduce the postoperative length of stay, in patients who had extensive pelvic dissection. The factors within ERAS and their application do not represent rigid schematizations but fluid concepts that may undergo substantial changes as soon as new evidence becomes available. The ERAS principles must be adapted to the specific environment and each team is expected to set up their own programme and quality control criteria. In this comprehensive review, the latest evidence and trend on enhanced recovery after rectal surgery have been critically appraised and presented.
