Formation of new zones: any group of societies wishing to form a new geographical zone must be supported by more than half of the national societies of digestive endoscopy within that area before applying for zonal status.

The organization is structured into an Executive Committee, as well as standing and ad hoc committees, responsible for different activities within the society.

The Executive Committee, in addition to the standing committees and the presidents of the member societies form the governing council of the organization.
