International Federation for the Surgery of Obesity and Metabolic Disorders - IFSO2022

Dear IFSO Members, Dear Colleagues,

First of all, we would like to THANK YOU all very much for your continuous support and participation in IFSO's activities throughout 2020 and 2021.


It's been a very tough period for all of us. The COVID-19 pandemic has challenged our lives in each and every aspect, but the vaccine has shown us the light at the end of the tunnel. 


As you know, last year we were forced to postpone the XXV IFSO World Congress to October 2021 with the hope that all our members would have been able to attend and that we could all get together again. 


This hope, unfortunately, hasn't become a reality yet, but the GOOD NEWS is that travel restrictions to the USA from most of the countries will be dropped towards the end of 2021 and in some cases in early 2022. 


So in order to give ALL our members the chance to attend, the IFSO leadership has decided to move the Congress to 23-27 August 2022.


All the future IFSO Congresses will be moved accordingly, so the XXVI IFSO Congress will be held in 2023 in Italy. 


This was not at all an easy decision, because we were all looking forward to meeting each other again in person, after two long and difficult years.


But we really feel we have to give all our members the same opportunity. It wouldn't be a real "IFSO Congress" without members from all our five Chapters. 

The program stays as it is and it will be even more interesting: ASMBS will participate with us with its two tracks, WOF and WGO will have their two sessions within our program, IFSO LAC will organize their sessions, in Spanish and Portuguese. In one word: IFSO will remain the biggest appointment for anyone working in the field of obesity surgery, and we don't want to leave anyone out!!



All accepted abstracts will be presented at the congress next year and published in Obesity Surgery Journal in 2022. If you want to withdraw your abstract and/or send an updated version, you can do so. You will receive further instructions from the local organizing secretariat.



As for the registration, you can lock in your registration for 2022 at the same registration fees you paid this year. No action is required if you would like to lock in this rate, the local organizing secretariat will simply keep your registration intact. 


If, instead, you prefer to cancel your registration, please email registration@IFSO2021.com  to start the refund process.  All requests to cancel will need to be initiated in writing no later than October 19, 2021, to receive a full refund. After October 19, 2021, the cancellation will be 50% refund per our cancellation policy.   



If you want to keep your reservation at the Fontainebleau Hotel at the conference room rate of $229 plus $34 resort fee and 14% tax per night, the hotel will require you to pay the first night room and tax to hold your reservation.


If you choose to cancel your hotel booking, the hotel will email your cancellation confirmation for your records and you will get your deposit back.

Please send an email to registration@IFSO2021.com by Friday, October 8, 2021  with your decision on whether you would like to keep, adjust or cancel your hotel stay


We know we are asking you for some more patience, but it's in the interest of all of you to offer you a safer and broader congress. 


Thank you for your understanding and for your loyalty to IFSO.


We guarantee it will be worth the wait!
