Experience with an Enhanced Recovery After Surgery (ERAS) Program for Bariatric Surgery: Comparison of MGB and LSG in 374 Patients

Background Strategic multidisciplinary protocols for “enhanced recovery after surgery” (ERAS) have demonstrated reductions in length of hospital stay (LOS), morbidity, and costs in conjunction with bariatric procedures. Methods We prospectively investigated the effectiveness and safety of an ERAS protocol with laparoscopic omega loop gastric bypass (“mini” gastric bypass, MGB) and LSG in morbidly obese patients. Results Average LOS was 1.24 days (range 1-14); 86.1% discharged on day 1; 96.9% by day 2, a value comparable or better than that of other ERAS studies vs standard care according to meta-analysis. Complications 2.9%; readmission 2.1%; reintervention 1.3%. Conclusion The program was equally safe with both procedures. Postoperative antithrombotic heparin does not appear necessary in low-risk patients. Bariatric surgical ERAS programs are evolving and not yet standardized.
