Welcome to the ACG 2025 Late-Breaking Abstract Submission Site
Late-breaking Abstract submissions are now being accepted.
The deadline to submit is Tuesday, August 26, 2025, at 11:59 pm (ET).
________________________________________________________________________________________________________________________
ACG will consider extending the Annual Scientific Meeting program to create a few additional oral presentation slots to accommodate late-breaking abstracts that detail high-quality clinical research results that were not available or fully analyzed by the June 2, 2025, general abstract deadline.
The College invites submissions of great merit and clinical research from gastroenterologists, internists, surgeons, hepatologists, radiologists, pediatricians, fellows-in-training, and advance practice providers. Both ACG members and non-members may submit abstracts.
The late-breaking abstract submission period runs from August 12-26, 2025 (11:59pm ET). No submissions will be accepted after the deadline. A nonrefundable processing fee of $70 (payable online via credit card in U.S. dollars) is required for each submitted abstract.
Notice of acceptance / non-acceptance will be emailed in early September to the person listed as the Presenting Author. The Presenting Author is responsible for notifying all co-authors of the decision, and the Presenter must officially accept the invitation to present.
Late-breaking abstract submissions must also adhere to the same overall requirements and guidelines as those for the general abstracts. (View the general abstract submission instructions.)
Additional Important Late-Breaking Abstract Information
- Do NOT resubmit abstracts already considered during the regular 2025 abstract review process. Late-breaking abstracts should describe high-quality clinical research results that were not available or fully analyzed by the June 2, 2025, general abstract deadline.
- Case reports and video submissions will NOT be considered.
- Late-breaking abstracts are considered only for oral presentation and not for poster presentation.
- Authors of accepted abstracts are required to present in person in Phoenix and register as an attendee of the ACG 2025 Scientific Meeting.
- Abstracts submitted during the late-breaking abstract process will not be published in the October supplement issue of The American Journal of Gastroenterology, however, authors are invited to submit complete manuscripts to the AJG to be considered for publication.
