Compliance with enhanced recovery after surgery criteria and preoperative and postoperative counselling reduces length of hospital stay in colorectal surgery: results of a randomized controlled trial.

AIM: The aim of this randomized clinical trial was to compare patients treated using a multimodal approach [enhanced recovery after surgery (ERAS)], with a special focus on counselling, to patients treated in a standard conventional care pathway, who underwent elective colorectal resection.

METHOD: In a single-centre trial, adult patients eligible for open or laparoscopic colorectal resection were randomized to an ERAS programme or standard care. The primary end-point was postoperative total hospital stay. Identical discharge criteria were defined for both treatment groups. Secondary end-points included postoperative complications, postoperative C-reactive protein levels, postoperative hospital stay, readmission rate and mortality. All parameters were recorded before operation, on the day of surgery and daily thereafter until discharge.

RESULTS: Total hospital stay was significantly shorter among patients randomized to ERAS than among the standard group [median 5 days (range 2-50 days) vs median 8 days (range 2-48 days); P = 0.001]. The two treatment groups exhibited similar outcomes regarding overall major and minor morbidity, reoperation rate, readmission rate and 30-day mortality. There were also no differences in tolerance of enteral nutrition or in the inflammatory response, as reflected by postoperative C-reactive protein levels.

CONCLUSION: ERAS care was associated with a significantly shorter length of hospital stay. Without any difference in surgical or general complications, tolerance of enteral nutrition or postoperative C-reactive protein levels, peri-operative information and guidance for ensuring that patients comply with the ERAS approach appear to be important factors to reduce the length of hospital stay.
