In 2012, for the first time, the development of the scientific program of the 11th World Conference is entrusted to a number (35) of Committees or "Interest Sections", each covering one of the topics chosen in an attempt to make an in-depth dissection of the theme of the congress.

Each Committee comprises a Chair, a Chair Elect, a Vice Chair, and 5 members, one of whom to be a Fellow appointed by the Chair.

The scientific renown of each of those having accepted to serve on the Committees secures the level of the program which will be proposed on this occasion.

For the 10 preceding conferences, the entire task of developing the scientific program was born by one, single person.
In the continuity of a cohesive method, these Committees were drawn up following the plan presented in Boston, based on the names of the volunteers that signed up at the end of the 10th OESO Congress.

This new, multi-directional way of building the content of the program is warmly welcome by the Executive Direction. The personal input of each one in this process is expected to be key to the scientific impact of the Como event.

The Chairs and members of the Committees have been asked:

  • to draw up a number of focused questions dealing with the discipline of the Committee in the spirit of  the original, specific format of OESO, that is, questions to be answered in no more than 300 seconds in Plenary Sessions or Special Sessions,
  • to propose ideas for Symposia or Topic Fora, each comprising 6 ten minute presentations, with 45 minutes for discussion.

A great number of proposals, from diverse Committees and diverse disciplines, came to the OESO Offices, and, according to the chosen title, a tentative program at a glance was made, avoiding overlaps, making a distribution of the various topics that could make the OESO 11th Conference, once again, a multi-disciplinary event in the field of esophagology.
