Enhanced recovery after bariatric surgery (ERABS) in a high-volume bariatric center

The growing demand for bariatric surgery has been accompanied by an expensive technological evolution and the need to contain healthcare costs and to increase the quality of care. The enhanced recovery after surgery (ERAS) protocols applied to the bariatric setting can be the answer to all these different issues.

Feasibility and safety of ERAS protocol in a single, high-volume bariatric center.

Humanitas Research Hospital, Rozzano MI, Italy.

Our ERAS bariatric protocol is based on the following 3 steps: (1) preoperative: optimization of all co-morbidities, counseling patients and family with information and education, and shortening fasting times (clear fluids up to 2 hr and solids up to 4 hr before induction of anesthesia); (2) intraoperative: premedication, parallel team work, awake patient positioning, standardized multimodal anesthesia and analgesia, noninvasive monitoring, video-laryngoscopy in reverse Trendelenburg position, short-acting anesthetic agents, and standardized laparoscopic surgery avoiding the nasogastric tube, catheter, and drain; and (3) postoperative: analgesia, early mobilization, early oral fluid, thromboprophylaxis, discharge planning, and follow-up telephone call. Clinical pathways were established and outcomes were retrospectively collected.

Comparison between conventional care and ERAS protocol reveals a reduction of the length of hospital stay (from 4.7 to 2.1 d) and a low morbidity rate. From July 2015 to July 2018, a total of 2400 consecutive patients underwent primary or revisional bariatric surgery (2122 sleeve gastrectomies and 278 Roux-en-Y gastric bypasses [RYGB]). Mean body mass index was 44.9 kg/m², mean age was 41.9 years, and the male to female ratio was 1:2.5. Total mean operative time was 85 minutes, with a surgical time of 65 minutes and an anesthesiologic/patient induction time of 4 minutes. Early complication rate was 3.5% with no perioperative mortality. Mean hospital stay was 2.1 days and the rate of readmission was .9%.

This study demonstrates that our ERAS protocol is safe, feasible, and efficient. Patient preparation and multidisciplinary/parallel team work are crucial points.
