BMJ Open Gastroenterology is an online-only, peer-reviewed, open access gastroenterology journal, dedicated to publishing high-quality medical research from all disciplines and therapeutic areas of gastroenterology (including the alimentary tract, the liver, biliary tree and pancreas). The journal publishes all research study types, from study protocols to phase I trials to meta-analyses, including small or specialist studies. BMJ Open Gastroenterology adheres to the highest possible industry standards concerning publication ethics.
BMJ Open Gastroenterology adheres to the highest standards concerning its editorial policies on publication ethics and scientific misconduct. The journal follows guidance produced by bodies that include the Committee on Publication Ethics (COPE), the World Association of Medical Editors (WAME), the Council of Science Editors and the International Committee of Medical Journal Editors (ICMJE). To view all BMJ Journal policies please refer to the BMJ Author Hub policies page.
Authors are required to submit a statement that their study obtained ethics approval (or a statement that it was not required and why) and that participants gave informed consent. Our Editors will consider whether the work is morally acceptable as determined by the World Medical Association’s Declaration of Helsinki. In addition to this, in line with General Medical Council guidelines, an article that contains personal medical information about an identifiable living individual requires patients explicit consent (in the format of a signed BMJ patient consent form) before we will publish it. Please find further details on BMJ research ethics policies (human participants and animals) and consent for publication; including a link to the downloadable consent form.
To make the best decision on how to deal with a manuscript, BMJ Open Gastroenterology needs to know about any competing interests authors may have; this includes any commercial, financial or non financial associations that may be relevant to the submitted article. Authors must download and complete a copy of the ICMJE Conflict of Interest disclosure form. In addition to this BMJ Open Gastroenterology ensures that all advertising and sponsorship associated with the journal does not influence editorial decisions, is immediately distinguishable from editorial content and meets all other BMJ guidelines. Please find more information about competing interests and a link to the form.
We take seriously all possible misconduct. If an Editor, author or reader has concerns that a submitted article describes something that might be considered to constitute misconduct in research, publication or professional behaviour they should forward their concerns to the journal. The publisher will deal with allegations appropriately following ICMJE and COPE guidelines. Corrections and retractions are considered where an article has already been published; corrections, expressions of concern or a retraction notices will be published as soon as possible in line with the BMJ correction and retraction policy.

BMJ is committed to transparency. Every article we publish includes a description of its provenance (commissioned or not commissioned) and whether it was internally or externally peer reviewed.
