Enhanced recovery after surgery (ERAS) protocol is well established in many surgical disciplines and leads to a decrease in the length of hospital stay and morbidity. Multimodal protocols have also been introduced to bariatric surgery.

3. Introduction
Bariatric Surgery - the most effective method of treating morbid obesity
Exponential increase in number of bariatric surgeries in India
ERAS guidelines for Bariatric surgery : published in 2016 in WJS by ERAS
Society
Pathways developed initially for elective colorectal surgery and later for
other surgical specialties
ERAS protocols have not been widely practiced by Bariatric Surgeons
4. What is ERAS ?
d
Pathways and facility culture
for a surgical specialty
Patient centered
Evidence based
Multidisciplinary
team developed
1.Reduce surgical stress
response
2.Optimize physiologic
function
3.Facilitate recovery
Enhanced recovery after surgery (ERAS) is a multi-professional
and multidisciplinary approach to the care of the surgical patient
5. History of ERAS
1990 s -- Fast track Surgery concept for cardiac surgery
Later to colorectal surgery
Care bundles to speed up recovery & discharge
1995-- ERAS - first outlined by a Danish surgeon, Henrik Kehlet
for colonic resections
2001 -- ERAS® Society (www.erassociety.org) - evidence based
pathways & extended to all surgical specialties
ERAS®Society implementation program - training module
8. Limited hospital beds; patient load increasing
Pressure for faster recovery & early discharge
Health care model is changing:
“Fee-for-service” “Pay for performance”
Enormous cost saving for insurers & managers
Why ERAS ?
9. Faster recovery
Fewer severe complications
Shorter Length of stay
Fewer readmissions
Full control of complex care
Increased staff satisfaction
Less workload for nurses
Large savings potential
Protocol and Care pathway compliance results in:
15. Enhanced Recovery in Bariatric Surgery
Why ??
Pre- admission work up and optimization done
Most of our patients go home on next day
Hard to improve LOS
Post op ileus is not an issue
Wound infection rates are quite low …
16. Pre Admission – Bariatric
Patient & family Education
Nutritional assessment & correction
Comorbidities optimization
Smoker: STOP 4 weeks before surgery
Alcohol: STOP
Multidisciplinary team consultation
Why ??

30. Results: Reduction 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 SG and 278 RYGB). Rate of readmission
was 0.9%.
Conclusions: This study demonstrates that our ERAS protocol is safe, feasible, and
efficient. Patient preparation and multidisciplinary/parallel team work are crucial
points
31. It is time that Bariatric surgeons
embrace ERAS and reap the benefits
