Late-Breaking Abstracts

The online submission period for late-breaking abstracts will be August 19 - September 3, 2019. Details will be made available on this site in mid-July. Authors of accepted late-breaking abstracts will be notified in early September, and must register for and present their abstract at the ACG 2019 Scientific Meeting.

Late-breaking abstracts must abide by the same submission guidelines and instructions required for abstracts submitted during the general March 11 – June 10, 2019 submission period.

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 abstract deadline (June 10, 2019).
  • 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.
