This session will discuss current controversies in technical optimization for achieving better results overtime in patients undergoing bariatric surgery, tips and tricks and alternative solutions in revisional-case scenarios. The topics will include a debate on controversies on:
a) Step-by-step technical systematization for SG and RYGB;
b) Revisional surgical and endoscopic options for failed or complicated situations;
c) Bariatric surgery for patients with gastro-esophageal reflux disease (GERD) and/or large esophageal hiatal hernias;
d) Patients with previous anti-reflux procedures;
e) Treatment for leaks after laparoscopic gastric bypass (LRYGB) or sleeve gastrectomy (LSG).

METHODOLOGY
In a 4-screen session discussion, case-videos examples will be used to help better delineate the most common scenarios and the different treatment options including revision of the recent relevant published data to enrich the discussion, as well guidance and tips to assist in treating these challenging patients.
