Submission and production processes
Articles illustrating basic mechanisms and their application to clinical material will be welcomed. We aim to cover all areas of Gastroenterology and Hepatology and through a system of commentaries and Recent Advances articles to make clear the relevance of scientific advances to clinical practice. The priorities are originality and excellence. We aim to ensure a fair and independent peer review system and to publish articles which follow the highest ethical standards concerning research conduct.
Authors can choose to have their article published Open Access for a fee of £1,950 (plus applicable VAT).
Colour figure charges
During submission you will be asked whether or not you agree to pay for the colour print publication of your colour images. This service is available to any author publishing within this journal for a fee of £250 per article. Authors can elect to publish online in colour and black and white in print, in which case the appropriate selection should be made upon submission.
Article types and word counts
- Original papers
- Leading Articles
- Case reports
- Letters to the editor
- GI Snapshot
- Recent advances
The word count excludes the title page, abstract, tables, acknowledgements and contributions and the references.
We invite authors to submit potential illustrations for the cover with their paper.
If you are not a native English speaker there is a professional editing service available.
For papers reporting original data (eg, controlled trials and intervention studies):
Word count: up to 4000 words. This does not include the title page, abstract, figure / table legends, references.
Structured abstract: up to 250 words.
Tables/ Illustrations: Images submitted should be those which uniquely display the data and not repetition of information available either in the text or as a table. Figures are not limited, but must be thoroughly justified. Please note that figure legends should be kept as brief as possible.
References: limited to those critical and relevant to the manuscript (around 50).
Authors should also complete a summary 'box' indicating the significance of this study as follows:
What is already known about this subject: 3-4 bullet points
What are the new findings: 3-4 bullet points
How might it impact on clinical practice in the foreseeable future?
The above headings must be used. Please add this in the manuscript file following the abstract.
Reports of randomised controlled trials should follow the revised CONSORT statement (Consolidated Standards of Reporting Trials.) published in JAMA (2001;285:1987-91), as closely as possible. See RCTs for more guidelines.
For primary research manuscripts reporting experiments on live vertebrates and/or higher invertebrates, we recommend following the ARRIVE reporting guidelines when documenting these animal studies. The guidelines were published in the online-only journal PLoS Biology in June 2010 and are now endorsed by over 40 high quality journals (the full list can be found here).
- Title Page
When you choose a title bear in mind that others will have to find your work using bibliographic searches. Check that it represents the content of the paper and is not misleading. Also suggest a short running head.
The title and authors' names should be typed on the title page and in the journal style. Inconsistency in the number of forenames or initials given for an individual author will mean that several versions of an author's name will appear in the index. Authors' degrees etc are not printed in Gut.
Authors of original scientific papers must supply a structured abstract of no more than 250 words under the following headings:

Gut welcomes Letters to the Editor. These should be related to a recent article published in Gut. Original data may be included if it is relevant and gives added weight to the comment on the previously published article.

Tables/Illustrations: up to 2.

This citable category is for unusual images that make an educational point. Since the aim of these articles is to stimulate the reader to think about the case, the title should be ambiguous and not give away the final diagnosis immediately, for example, "Recurrent vomiting in 90 year old female".
GI snapshots will appear in two parts. The first part should contain a very brief clinical introduction to a case (maximum 200 words) followed by an image and a question designed to stimulate the reader to think about what the image shows. The legend should not indicate the diagnosis but should simply describe the nature of the image e.g. 'endoscopic view of second part of duodenum'. The second part (maximum 200 words) will appear later in the issue should contain the answer. The answer should include a brief description of the key diagnostic features of the image, the outcome, and a teaching point. GI snapshots will not include more than 5 references.
The quality of the image must be at least 300dpi and in TIFF, JPEG, GIF or EPS format.
Videos are also welcome and should be in .mov, .avi, or .mpeg format. They should be offered as two different files, one for viewing at lower speed connections, and of low resolution; and one for higher speed connections, of high resolution. For a good example of this at work see http://www.bjophthalmol.com/video/collection.dtl - click on a [View video] link and you'll see one video for dial-up and one video for fast connections.
These are commissioned only articles. Original papers should not be submitted under this title.

- A sponsoring organisation, often a pharmaceutical company or a charitable foundation, that wishes to arrange a meeting, the proceedings of which will be published as a supplement.
In all cases, it is vital that the journal's integrity, independence and academic reputation is not compromised in any way.
When contacting us regarding a potential supplement, please include as much of the information below as possible.
- Journal in which you would like the supplement published
- Title of supplement and/or meeting on which it is based
- Date of meeting on which it is based
- Proposed table of contents with provisional article titles and proposed authors
- An indication of whether authors have agreed to participate
- Sponsor information including any relevant deadlines
- An indication of the expected length of each paper Guest Editor proposals if appropriate
For further information on criteria that must be fulfilled, download the supplements guidelines (PDF).
