Welcome to OESO
The OESO-SEMPIRE 17th World Conference – Esophagus 2026
Every effort was made to ensure that this 17th Congress of OESO would be on par with the 16 previous ones!
- First, the venue chosen for the event: Versailles!
Versailles, a name synonymous with legend, was opened to us for our congress.
The exceptional authorizations granted by Mr Pierre-Emmanuel Lecerf, President of the Domaine de Versailles, to a private organization like ours to access certain parts of the Domain gave participants the opportunity to enjoy a very special program of festivities. Among these offers were a custom-designed equestrian show, a private tour of the Carriage Gallery, and private access to the historical Jeu de Paume Hall where the French Republic was born, and in which the members of the new OESO Board read before all the congress attendees, beneath the statue of Bailly’s oath, the text of the OESO Charter...
Although the schedule for the final afternoon of the congress had to be altered due to the unexpected visit by... the US President Donald Trump, those who were with us benefited nevertheless from a host of memories that would remain with them a long time.
- The top level scientific program which, as it has been since the very beginning of the OESO, was multidisciplinary, this year included 15 sessions in a new format that has since become the standard for future OESO events: a 50-minute “chat” between the speakers and the audience.
The attendees represented over 40 countries, and gathered in three auditoriums operating simultaneously to hear answers to specific questions that had been formulated in detail by the members of the Scientific Committee.
The excellence of the presentations, the stimulating discussions, and the fruitful exchanges between participants contributed to making this congress a truly enriching experience. The active engagement of all speakers, chairpersons, and attendees created an exceptional atmosphere of collaboration and knowledge sharing.
- The Platform for Excellence in Esophagology, with a memorable session welcoming 3 new Pilot Centers joining those already spread across the five continents, can now be considered as the spearhead of OESO-SEMPIRE in shaping its future.
Yes, this 17th congress, bringing together leading experts from around the world in Versailles was an outstanding scientific event.
The Organizing Committee extends its sincere gratitude to all participants for their valuable contributions, which played a key role in the remarkable success of this edition of the OESO-SEMPIRE World Conference.

Welcome to OESO
Focusing on Esophagology has led OESO, since its founding, to set a standard of innovation of a unique scope, considering its basic structure and the scientific level of its inter-university global partnership. The primary interest of what has been built in its international, multi-disciplinary program, lies in its approach to expand knowledge across the disciplines related to one organ, and to share this knowledge in a way that will ultimately benefit patients.

Global Education in Esophagology
Virtual Global interactive clinical cases discussions
I am really so grateful!
I am asking if it is possible to have the links for all the previous sessions because for me these represent the best method for continuous medical education and to improve the experience of my staff by watching these sessions and listening to the fruitful discussions…"

(Head, upper GI unit, Ain Shams University of Cairo) June 13, 2023
The topic and time is announced well in advance on the OESO website and the OESO Newsletters with specification of the time to allow connection at a comfortable hour of the day.
The latest, innovative OESO-SEMPIRE project, proposes a series of “Gatherings in Esophagology” (GiE) at the Abbey of Royaumont in the period between two OESO international congresses, thus maintaining a continuous flow of interest in Esophagology.
*
KOLs and Juniors living together, morning to evening, in an intimate atmosphere to foster open discussions and networking.
-
A prestigious venue, the Abbey of Royaumont,
20 minutes from Roissy Charles de Gaulle Airport -
Several KOLs, together for 36 hours
-
A limited number of participants to share this time with them, and deepen their knowledge on a specific point of multi-disciplinary gastroenterology
-
A single theme for reflection (Esophageal disease – Esophageal exploration – Treatment applicable to an esophageal disease)
OESO-SEMPIRE 1st GiE on Reflux Diseases
Friday 30th and Saturday 31st May, 2025
A Worldwide Multidisciplinary Platform
A training and educational tool dedicated to the foregut is ready to offer its services to the scientific community. A multidisciplinary Platform fostering the exchange of data, knowledge, and best practices, harnessing the newest technologies available globally.
A global network
Each Pilot Center has a "landing page".
The implementation of the Platform provides:
- easy and permanent Interaction with other Pilot Centers,
- access to a Multimedia Center, content library (articles, videos),
- opportunity to highlight research and/or scientific results
The detailed content of the landing pages for each Pilot Center (Team members, activities, research) is available on the Platform website.
37 Pilot Centers of Excellence
Missions in Developing Countries
The OESO missions in Developing Countries initiative, carried out in the framework of the Chair for Distance Learning awarded by the UNESCO, concern Centers which can benefit from special training sessions in laparoscopic surgery and endoscopy.
The beneficial role of GI endoscopy for the prevention, diagnosis, and treatment of many digestive diseases is well established, as well as for the exploration and dilation of caustic stenoses very frequent in young children following ingestion of caustic liquids.
The OESO World Congresses
The OESO-SEMPIRE 17th World Conference –Versailles (France) – Palais des Congrès –June 14-17, 2026
Each OESO congress brings together 500 to one thousand delegates from 60 to 70 countries, each dealing with ONE topic in esophagology dissected into hundreds of sharp questions, according to the original, specific OESO format.
- OESO was born as a wager, at a time when the compartmentalization of disciplines made any attempt at multi-disciplinarity illusory.
- OESO has made it possible from its first world congress in 1984 to its 15th in 2019.
- OESO will continue to do so in the congresses that follow
The OESO Encyclopedia
of Esophagology
Cooperation between OESO and the New York Academy of Sciences
Each book is a sequence of structured review articles, with illustrations, tables and complete bibliographical references focused on a single question of the program.
UNESCO
The single goal of OESO and OESO-SEMPIRE is Education in the field of the foregut. It is the image of one of the missions of UNESCO for dissemination of information and sharing of knowledge.
The poly-disciplinary potential magnitude of the OESO-SEMPIRE network is evidenced by a Resolution approved at the General Conference of UNESCO and 2 Chairs granted to OESO and to the OESO Foundation.

We, all of us in OESO,
have spent more than 3 decades building this innovative esophagology training partnership which fosters the exchange of data, knowledge, expertise, and best practices between global centers of the OESO network.
A fundamental step for Esophagology was taken with the Platform of Excellence set up with SEMPIRE to adhere to the principle of multi-disciplinarity OESO has nurtured since its founding.
