COS is now accepting abstracts online for the 2021 COS Annual Meeting. The abstract submission deadline is Monday, November 9, 2020 at 11:59 PM ET.

In addition to paper (oral) presentations, we are pleased to introduce two additional forms of presentation:

  • ePosters: Say goodbye to poster tubes and printing – All accepted posters will be offered as electronic poster (ePoster) presentations.
  • Surgical Videos: Show off your surgical skills by submitting a video. COS is now accepting surgical videos to be displayed alongside the ePosters (maximum five (5) minutes in duration).

The COS Annual Meeting historically boasts an 80+% acceptance rate with abstracts making up over 50% of all presentations. With so many abstracts, it is important to set your research apart – follow these keys to a successful submission when drafting your abstract or editing your video:

  • List all authors/co-authors/producers; and declare all financial interests for each author/co-author/producer.
  • Indicate that ethics approval has been obtained, where required.
  • Submit your abstract to the appropriate subspecialty session.
