Submissions should be made through the BMJ Open Gastroenterology Research Submission Site. All submissions are subject to external peer review. Submission to the journal implies that the work described has not been accepted for publication elsewhere, that it is not under consideration for publication elsewhere and does not duplicate material already published.
