2019_POSTER Membership bees.indd 1 21.12.2018 16:26:09 14th Congress of ECCO • March 6-9, 2019 • Copenhagen, Denmark

Word of welcome Dear Colleagues,

Welcome to the 14th Congress of ECCO in the wonderful city of Copenhagen, Denmark! Copenhagen blends tradition and state-of-the-art design in a city full of contrast and balance. The qualities of this city are reflective of what is valued in this year’s congress programme. In this country of continuous and significant medical research, the ECCO Congress is in an environment that embraces new methods and research while holding on to well-established knowledge and Silvio Danese traditions.

After a very successful ECCO Congress in Denmark in 2014, it is a great privilege to return to Bella Center for the ECCO Congress in 2019. The immense growth in the recent years has firmly established the ECCO Congress as THE major IBD meeting in the world. Attracting over 6,500 participants, ECCO offers opportunities for nurses, dietitians, surgeons, gastroenterologists and physicians in the field of IBD to exchange knowledge and participate in a growing spectrum of Educational Courses and Masterclasses. Additionally, ECCO reaches out to young clinicians and scientists offering this international platform to pursue improvement in every pillar of IBD patient care.

As we witness major breakthroughs of innovation in new drugs hitting clinics and also new personalised approaches for individual patient treatments, the ECCO Congress theme for this year is suitably titled “Research drives clinical care”.

The Congress sessions are focused on the present best practices for adult IBD patients, including paediatric and surgical lectures, and also highlighting the newest trends for patient management. As new challenges in IBD approach, now, more than ever, research must strive for best clinical care. For this reason, active participation and interaction is vital and fuels success in reaching our goal of improving IBD patient care.

On behalf of the whole ECCO Team and the Organising Committee, I extend a warm welcome to you all!

Yours sincerely,

Silvio Danese ECCO President 2018-2020 & Chair of Organising Committee

Scientific Information: A-Z Abstracts ECCO is proud to announce that a total of 1228 abstracts have been submitted to the 14th Congress of ECCO. A panel of expert reviewers have evaluated and selected the strongest, most scientifically relevant abstracts for presentation at this year’s Congress. Authors of the best abstracts have been invited to present their studies as oral presentations, digital oral presentations and hard copy poster presentations. For details regarding abstract presentation, see pg. 37. Business meetings Attendance at business meetings is upon invitation only. The General Assembly will be held in C1-M1 at Bella Center, on Thursday, March 7, 20:00-21:00. Stop by the ECCO Booth for more information on business meetings. Compliance Based on the EFPIA HCP Code and the guidelines and codes of practice applicable to Denmark, ENLI (Danish Ethical Board for Pharmaceutical Industries) and the Danish Medicines Agency, ECCO has adopted measures that allow compliance with applicable regulations regarding publicity and promotion of medicines at the ECCO Congress 2019. ••Exhibitors have been asked to respect the Code of Practice in the context of the ECCO’19 Exhibitor & Sponsor Prospectus. ••Exhibitors have been alerted to the regulations about the promotion of prescription-only medicine, explaining that non-HCPs congress delegates can be identified with the non-HCP sign on the congress badge. Furthermore non-HCPs have no access to areas where advertising for HCPs is allowed. ••In the course of the online and onsite registration, the congress delegates are also informed about the regulations regarding publicity and promotion of medicine and are asked to indicate their HCP/non-HCP status accordingly. Disclosure policy ECCO has diligently maintained a disclosure policy of potential Conflicts of Interest (CoI) with the aim of fostering transparency and ensuring scientific rigour and objectivity in all scientific and educational activities. Therefore, all presenters, including invited faculty members and abstract presenters, are required to disclose relevant financial support and relationships that may generate potential conflict. Please note that the presenting author holds responsibility for the content of his or her presentation.

All presenters are required to complete a Conflict of Interest form disclosing any financial support and advisory/consultancy roles in the biomedical industry. These forms are made public on the ECCO Website at www.ecco-ibd.eu/about-ecco/ecco-disclosures providing a comprehensive overview of potential Conflicts of Interest of presenters. Once published, the ECCO Office will notify IBD Community in an eNewsletter of the online access to the up-to-date CoI forms.

All conflicts are to be disclosed on the nd2 slide of each PowerPoint presentation. To facilitate and reinforce the 2nd slide policy, faculty speakers are reminded to disclose their potential Conflicts of Interest in their presentation in line with European Union of Medical Specialists (UEMS) regulations.

March 6-9, 2019 • Copenhagen, Denmark 11 Scientific information: A-Z

A draft CoI slide will be prepared for each speaker based on the submitted CoI form, and will be made available in the Speakers’ Centre to be included in the presentation. Please be reminded that if the respective presentation does not yet include a disclosure form, the slide draft should be checked and amended before it is inserted into the presentation.

Conflicts of Interest may include, but is not limited to, financial relationships, whether the individual had the opportunity to influence the content of a presentation, grants, honoraria, shares, and paid positions on advisory boards. ECCO expects many presenters to have some Conflicts of Interest, which do not prevent them from presenting their work given that the conflict is disclosed. EACCME – Continuing Medical Education The 14th Congress of ECCO in Copenhagen is accredited by the European Accreditation Council for Continuing Medical Education (EACCME) to provide the following CME activities for medical specialists.
