Welcome message from Robert Giuli

This is the 17th time OESO is announcing its world congress, fourty-one years after the first one in 1984. 

During these 4 decades, OESO has, with perseverance, ploughed a road exclusively directed towards a single goal: Education and the sharing of knowledge, at the highest level in the world, and in all disciplines, applied to one, single organ of the human body: the esophagus. 

The world’s leading universities, UNESCO and the New York Academy of Sciences have shown, and continue to show, the place OESO now occupies in the international scientific community. 

And today OESO, now OESO-SEMPIRE, is proud to have set up a unique project with Stanford University: the Platform of Excellence in Esophagology, which brings together a growing number of Pilot Centers in the five parts of the world, united by the same desire to contribute to sharing of knowledge, the very essence of OESO. 

The 17th World Congress will be the evidence of this spirit: 
You MUST be there, in Versailles!

The OESO-SEMPIRE Scientific Program  

The scientific program is based on sessions of 90 minutes (1h30).

A new, original format will be applied to 15 “Chat sessions”:

  • At the start of these sessions, an informal 10-minute chat between the two chairs will enable them to introduce the questions to follow, explain their design, and discuss their terms.
    This free conversation on the stage will allow the audience to grasp the reasons behind the choice of the questions that were considered to best shed light on the topic of the session.
  • Six questions will follow, according to the OESO format, with answers given in 5 minutes by a speaker considered as an expert in the domain.
  • After 30 minutes and 6 answers given to these questions, the speakers will join the chairs on stage, to take part in an intense 50-minute discussion between themselves and with the audience, to wind up the session.

 

In addition of 3 pre-congress courses and poster / abstract sessions, 
# half of the scientific program (15 sessions) is based on this model,
but with 2 different types of sessions:

  • 7 sessions will apply the format in 90 minutes: Sessions 7-16-20-23-26-29-32

  • 4 grand sessions, with broader subjects, will apply it over two consecutive sessions (3h): Sessions 2-5, 8-11, 14-17, 21-24


Furthermore,

  • 18 sessions will comprise traditional presentations of 6 minutes each, followed by 3 minutes of discussion: 
    Sessions     1-3-4-6-9-10-12-13-15-18-19-22-25-27-28-30-31-33


With 180 traditional presentations, 90 answers to high level scientific questions and 270 speakers, the program of the congress will therefore deliver to the scientific community a message that will be an exceptional synthesis with, in addition, presentations of all selected abstracts.


It will correspond in the best possible way to the title of Congress:
“Esophagus 2026”.
