Enhanced recovery for colorectal surgery: Practical hints, results and future challenges.

Enhanced recovery after surgery (ERAS) protocols are now achieving worldwide diffusion in both university and district hospitals with special interest in colorectal surgery. The optimization of the patient's preoperative clinical conditions, the careful intraoperative administration of fluids and drugs and the postoperative encouragement to resume the normal physiological functions as early as possible has produced results in a large amounts of studies. These approaches successfully challenged long-standing and well-established perioperative managements and finally achieved the status of gold standard treatments for the perioperative management of uncomplicated colorectal surgery. Even more important, it seems that the clinical improvement of the patient's clinical management through ERAS protocols is now reaching his best outcomes (length of stay of 4-6 d after the operation) and therefore any further measures add little to the results already established (i.e., the adjunct of laparoscopic surgery to ERAS). Still dedicated meetings and courses around the world are exploring new aspects including the improvement the preoperative nutrition status to provide the energy necessary to face the surgical stress, the preoperative individuation of special requirements that could be properly addressed before the date of surgery and therefore would reduce the number of unnecessary days spent in hospital once fully recovered (i.e., rehabilitation, social discharges), and finally the development of an important web of out-of-hours direct access in order to individuate alarm symptoms in those patients at risk of complications that could prompt an early readmission.
