The general abstract submission period for ACG 2026 has closed.

The submission deadline was Monday, June 1, 2026 at 11:59 p.m. Eastern Time. We are not able to accept any modifications, additions, corrections, or author changes to either submitted or accepted abstracts. Authors identified as the Presenting Author will be notified by email regarding acceptance or non-acceptance of the abstract by or before July 31. Please do not contact the ACG Office prior to this date to inquire about the status of your abstract. The Presenting Author is responsible for notifying all coauthors of an abstract’s acceptance.

Embargo Policy: All research presented at ACG 2026 is strictly embargoed until 12:00 pm CT/1:00 pm ET on Sunday, October 11, 2026. The embargo policy means that no news, information, results of any abstract, or research finding can be released to the media or published before 12:00 pm CT/1:00 pm ET on Sunday, October 11, 2026. This embargo includes revealing anything about the results (including the title of the abstract, since often times the title indicates the finding) in a press release or “curtain raiser.” If you have questions, please email mediaonly [at] gi [dot] org ACG Media Staff. Accepted abstracts are available online prior to ACG 2026, for attendees’ planning purposes. The embargo policy applies to all abstract data regardless of when it is made available/published in ACG resources.
