Welcome to the ACG 2019 Abstract Submission Site

The Abstract Submission Site for the ACG 2019 Annual Scientific Meeting is now closed.

ABSTRACT NOTIFICATIONS: Abstract acceptance/non-acceptance notifications were emailed to Presenting Authors on July 12th. If you submitted an abstract and did not receive an email on July 12th, please contact ACG via email at, or call ACG at 1-301-263-9000. The deadline to respond to an invitation to present an abstract is 5:00pm (Eastern Time) on Friday, July 19, 2019. Please note: You may not have received notification if your email address changed since your abstract was submitted, or if your institution’s email server blocked the email or rejected it as possible spam.

Please note that we cannot make any modifications, additions, corrections, or changes of any kind to submitted abstracts, and no changes to the assigned presentation dates or times will be permitted.

Abstract Notification of Acceptance and Non-Acceptance

All notifications of acceptance or non-acceptance were sent by email on July 12th to the person listed as Presenting Author for the abstract. The Presenting Author is responsible for notifying all co-authors.

All Presenting Authors will be required to officially accept the invitation to present their abstract by Friday, July 19, 2019, and should register for the Annual Scientific Meeting no later than October 1, 2019 as an attendee for the meeting and present the abstract at the assigned date and time. For information about visas and/or formal letters of invitation, please go to this page.

Authors were notified of presentation dates and times at the time of notification of acceptance and are expected to make appropriate travel arrangements to ensure that at least one of the abstract’s authors will be in attendance. No changes to the assigned presentation dates or times will be permitted.

If you have questions, please email

Late-breaking Abstracts

The late-breaking abstract submission period will take place August 19-September 3, 2019. Details about the late-breaking abstract submission process are now available in the abstracts section of our meeting website.

Guidelines for late-breaking abstracts will be the same as for the general submission period abstracts, with the following exceptions:

  • Abstracts will be considered if they detail high-quality clinical research results that were not available or fully analyzed at the general (June 10, 2019) abstract deadline.
  • Abstracts that were already considered during the general abstract period should not be resubmitted.
  • Clinical vignettes, case reports, and video submissions will not be considered.
  • Late-breaking abstracts are only considered for oral presentation and not as posters.
