Late-breaking Abstracts

The late-breaking abstract submission period will take place August 16-September 2, 2021. Visit our late-breaking abstract page for details.

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 21, 2021) 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• Late-breaking abstracts are only considered for oral presentation and not as posters, and will not be published in the supplement to the October issue of The American Journal of Gastroenterology.
