Welcome to WCOG at ACG2017 The International GI Educational Event of the Year! Dear Colleagues, Welcome to the World Congress of Gastroenterology (WCOG) at ACG2017. This collaboration between the American College of Gastroenterology (ACG) and the World Gastroenterology Organisation (WGO) sees the return of the World Congress of GI to the United States for the first time in more than two decades. This is the premier clinical GI event of the year. The educational opportunities at the Postgraduate Course, Scientific Meeting, and Friday courses are unparalleled. Carol Burke The joint Scientific Programming Committee and Planning Committee, along with the Postgraduate Course Directors and the Friday Course Directors, have brought together internationally recognized experts and rising stars in the field. This year’s program promises to deliver the latest clinical updates in gastroenterology and hepatology, plus discuss of what is on the horizon that may impact your practice. We are thrilled that throughout the event there will be sessions that offer simultaneous Spanish interpretation — a first for a World Congress of Gastroenterology. 2017 was a record-breaking year for abstract submissions. You’ll find more than David Bjorkman 2,600 posters and oral presentations this year. Poster presentations open on Sunday beginning at 3:30 pm. Posters may be found in the Exhibit Hall. A popular activity for viewing posters is Poster Rounds with the Experts. Each day of the poster sessions, well-known experts will lead attendees around to posters of interest. In recognition of the larger than normal international presence at this meeting, we will have experts leading groups of attendees in a number of different languages. Signs in the convention center will provide the complete list and schedule. This is a great opportunity to discuss posters, garner insight from the experts, and make new contacts with other attendees in a low-key, relaxed environment. Poster Rounds with the Experts run from Sunday through Tuesday. Learn about the latest tools available and techniques from leading experts when you visit the ACG Hands-on Endoscopy Workshop Center to participate in one of the many sessions offered free to all WCOG at ACG2017 attendees. You can pre-register for these sessions at the special Hands-on Registration desk in the main Registration area and in the Exhibit Hall. Hands-on sessions are offered Sunday through Tuesday. Learn more on pages 22-23. Don’t forget to attend the Exhibit Hall Opening Reception, on Sunday, October 15, from 5:15 pm – 7:00 pm, immediately following the Postgraduate Course. The largest social event at the meeting, it is a great opportunity to enjoy food and drink with colleagues and friends and to explore the Exhibit Hall in support of the meeting’s sponsors. In closing, we want to thank you for joining us for this historic event that will showcase the best in clinical GI from around the world. We hope you have an opportunity to build bridges with your colleagues from around the country, the Americas, and the entire world.

WCOG at ACG2017 Scientific Meeting Planning Subcommittee Disclosure Declarations The American College of Gastroenterology (ACG) is accredited by the Accreditation Council for Continuing Medical Education (ACCME) to provide continuing medical education for physicians. ACG, as an ACCME accredited provider, ensures balance, independence, objectivity, and scientific rigor in all of its directly and jointly provided education activities. All who are in a position to control the content of an education activity (including their spouse or partner) are required to disclose to ACG all relevant financial relationships in any amount occurring in the past 12 months with any commercial interest that may create a conflict of interest related to the subject matter of an education activity. Safeguards against commercial bias have been put in place by ACG. Anyone who refuses to disclose relevant financial relationships will be disqualified. ACG ensures any conflicts of interest are resolved before the educational activity occurs and discloses all relevant financial relationships to the learners prior to the beginning of an education activity. Commercial Interest The ACCME defines a “commercial interest” as any entity producing, marketing, re-selling, or distributing health care goods or services, consumed by, or used on, patients. The ACCME does not consider providers of clinical service directly to patients to be commercial interests. Financial Relationships Financial relationships are those relationships in which the individual benefits by receiving a salary, royalty, intellectual property rights, consulting fee, honoraria, ownership interest (e.g., stocks, stock options or other ownership interest, excluding diversified mutual funds), or other financial benefit. Financial benefits are usually associated with roles such as employment, management position, independent contractor (including contracted research), consulting, speaking and teaching, membership on advisory committees or review panels, board membership, and other activities from which remuneration is received, or expected. ACCME considers relationships of the person involved in the CME activity to include financial relationships of a spouse or partner. Relevant Financial Relationships The ACCME defines “’relevant’ financial relationships” as financial relationships in any amount occurring within the past 12 months that create a conflict of interest. The ACCME has not set a minimum dollar amount for relationships to be significant. Inherent in any amount is the incentive to maintain or increase the value of the relationship. The ACCME considers financial relationships to create actual conflicts of interest in CME when individuals have both a financial relationship with a commercial interest and the opportunity to affect the content of CME about the products or services of that commercial interest. Conflict of Interest Circumstances create a conflict of interest when an individual has an opportunity to affect CME content about products or services of a commercial interest with which he/she has a financial relationship. All ACG Staff have indicated no relevant financial relationships. The WCOG at ACG2017 Scientific Meeting Planning Subcommittee Members have noted the following relationships with a Commercial Interest:

Paper/Poster Industry Involvement Disclosures

The American College of Gastroenterology (ACG) is accredited by the Accreditation Council for Continuing Medical Education (ACCME) to provide continuing medical education for physicians. ACG, as an ACCME accredited provider, ensures balance, independence, objectivity, and scientific rigor in all of its directly and jointly provided education activities. All who are in a position to control the content of an education activity (including their spouse or partner) are required to disclose to ACG all relevant financial relationships in any amount occurring in the past 12 months with any commercial interest that may create a conflict of interest related to the subject matter of an education activity. Safeguards against commercial bias have been put in place by ACG. Anyone who refuses to disclose relevant financial relationships will be disqualified. ACG ensures any conflicts of interest are resolved before the educational activity occurs and discloses all relevant financial relationships to the learners prior to the beginning of an education activity. Information on the Genesis of Study Concepts and Design: Author Responsibility The American College of Gastroenterology has supplemented the current conflict of interest disclosure with an additional series of questions completed by the authors of abstracts indicating whether they have been actively and personally involved in developing the study’s concept and design and in collecting the data to assure that authors are not reporting data actually collected and developed by others, e.g., a pharmaceutical company or other commercial entity. An abstract not referenced below indicates that the authors reported no industry involvement took place in any aspect or phase of the research.
