Enhanced Recovery After Bariatric Surgery: Feasibility and Outcomes in a National Bariatric Centre

Purpose This study aimed to assess outcomes of bariatric surgical procedures after the implementation of an enhanced recovery after bariatric surgery protocol in the National Bariatric Centre in Ireland. Materials and Methods Data on consecutive bariatric procedures performed over a 36-month period was prospectively recorded. ERABS interventions utilized included preoperative counselling, shortened preoperative fasts, specific anaesthetic protocols, early postop mobilization and feeding, and extended post-discharge thromboprophylaxis. Results A total of 280 primary bariatric procedures were performed over a 36-month period. The primary procedures were laparoscopic sleeve gastrectomy (57.5%), laparoscopic one anastomosis gastric bypass (33.2%) and laparoscopic Roux-en-Y gastric bypass (9.3%). Mean (SD) age was 48 (+/- 10) years, mean (SD) preoperative BMI 49.5 (+/- 9) kg/m(2) and 68% were female. Median ASA score was 3, and median OSMRS also 3. Over 50% of patients had a diagnosis of hypertension or OSA, and over one-third had a diagnosis of type 2 diabetes mellitus or dyslipidemia. All procedures were completed laparoscopically and 29 patients underwent a simultaneous procedure. The mean (SD) length of stay was 2.3 (+/- 1.4) days (median 2 days, range 2-47 days). Overall postoperative morbidity rate was 10.0% (n = 29). The 30-day readmission and reoperation rates were 3.6% and 2.5% respectively. There was no mortality recorded in this series. Conclusion Implementing an ERABS protocol was feasible, safe, associated with low morbidity, no mortality, acceptable LOS and low readmission and reoperation rates. Although patients with obesity have a spectrum of disease-related complications, this should not preclude the use of an ERABS protocol in bariatric surgery.
