Abstract Submission Guidelines

These are the rules for the submission of papers to be evaluated by the Congress Scientific Committee for acceptance. Papers shall be sent only through the official website (see here); no other channels will be accepted. The Scientific Committee in turn will appoint a five-member Selection Committee in charge of selecting the papers.

From all the papers accepted for presentation, the Selection Committee will select 3 (three) Outstanding Papers, on the grounds of their relevance, originality, methodology and conclusions. In recognition, they will be awarded a digital Diploma and one complimentary registration to the next Pan-American Congress of Gastronterology per paper. The authors of a paper thus selected will agree on who will enjoy it, and kindly provide the beneficiary’s name to the OPGE Secretariat (secretaria@opge.org).


The deadline for submission of abstracts is May 10, 2021, at 23:59.

Notifications of acceptance of papers will be e-mailed by May 20, 2021.

The presenter of each paper must be registered at the Congress and will be allowed to pay up to and including June 14, 2021. If the author selects any form of payment other than PAYPAL, he/she will be able to complete the registration and pay later.

Only one certificate will be issued per paper submitted.

Papers may be submitted in Spanish, Portuguese and/or English.

Authors will be listed in the same order as entered. Please include: First Surname, First Name, Institution, City, Country, and e-mail address. Include the name of the speaker or presenter.

The author responsible for submitting the paper undertakes to ensure that all co-authors are aware of the full content of the paper and that all relevant ethical and legal standards have been met.

Papers may be submitted in different categories: original papers, clinical cases, or videos.

No papers previously published or presented at other congresses will be accepted.

Although the authors will be able to express the desired form of presentation, the Scientific Committee will define the final format of the original papers (oral or poster). Clinical cases will be presented as posters.

The final decision of the Scientific Committee and Selection Committee may not be appealed and will be considered final.


1. The person responsible for the paper must create their user profile or complete the registration for the submission of the abstract (not the payment), completing all the fields requested.
