Stage one
Check that the work belongs here
The journal publishes research on disorders of the digestive system — the gastrointestinal tract, liver, biliary system and pancreas — and on the methods by which those disorders are diagnosed and assessed.
Eligibility follows the subject. A study is not required to demonstrate a clinical outcome or a new technique to be considered; it is required to support the claims it makes. The full statement is on the aims and scope page.
Research Article
Original investigations, including clinical, translational, mechanistic, diagnostic-accuracy and population studies.
Review Article
Critical syntheses of the evidence on a defined question in digestive disease or its diagnosis.
Systematic Review and Meta-analysis
A review carried out to a stated protocol, reporting how studies were sought, selected and appraised, with quantitative synthesis where the data allow it.
Methods Article
A method, assay, protocol or analytical approach, described together with the evidence that shows how it performs.
Data/Resource Article
A dataset, cohort, registry, biobank or comparable resource, described together with what it can be used to study.
Short Communication
A concise report of a focused finding or observation.
Case Report
A documented presentation, diagnostic course or complication that teaches something generalizable.
Invitation only
Two further formats are published at the journal’s invitation rather than through open submission: Editorial — invitation only, and Perspective/Commentary — invitation only.
Stage two
Assemble the manuscript
01
Structure
Research articles follow the usual sequence: title page, abstract, keywords, introduction, materials and methods, results, discussion, conclusion, declarations and references. Reviews, case reports and letters follow the structure appropriate to the format.
02
Title page
Full title, every author’s name and affiliation, the corresponding author’s contact details, and any funding acknowledgment. The title page is supplied as a separate file.
03
Abstract and keywords
A structured abstract for research articles, and keywords describing the subject, the population or material, and the method. These are what readers and indexing services see first.
04
Figures and tables
Each figure and table is numbered, cited in the text in order, and carries a caption that can be read on its own. Supply figures at a resolution that stays legible in print.
05
References
Cite the sources the argument actually rests on, in a single consistent style, with complete details for each entry so a reader can find it.
Stage three
Declarations the journal requires
Ethical approval
State the approving institutional review board or ethics committee and the consent obtained. Research involving animals states its institutional approval.
Trial registration
Interventional clinical trials must be registered in an accepted public trial registry at or before the first participant provides consent for enrollment. The registry name, registration number, and registration date must be reported in the manuscript.
Data availability
Every empirical research manuscript must include a data-availability statement.
Competing interests
Declare financial and non-financial competing interests for every author, or state that there are none.
Authorship
Every listed author has contributed substantially, has drafted or critically reviewed the manuscript, has approved the submitted version, and accepts accountability for it.
AI use
Disclose any use of AI tools in preparing the manuscript. Authors remain accountable for the whole of the submitted work.
Reporting guidelines
Use the reporting guideline that matches the design: CONSORT for randomized trials, STROBE for observational studies, PRISMA for systematic reviews, STARD for diagnostic-accuracy studies, CARE for case reports, and ARRIVE for animal research.
A completed checklist submitted with the manuscript helps reviewers assess the work against the standard its design implies.
Stage four
Submit
Single-blind by default; double-blind review is available on request. If you request double-blind review, prepare the manuscript accordingly before submitting.
For double-blind review, remove author names, affiliations, acknowledgments, funding details, institution names, and other identifying information from the reviewer manuscript. Provide identifying information separately in the title-page file or submission form.
Alternative route
A simple submission form that opens with this journal already selected.
Assisted route
Editorial email, for authors who would rather send the manuscript to the office directly.
One route only
Authors must use only one submission route for the same manuscript.
After submission
What happens next
All submissions undergo initial editorial screening. Manuscripts that meet the journal's scope and minimum requirements proceed to independent peer review.
Manuscripts that proceed to external peer review are normally evaluated by at least two independent subject-matter experts. Editorial decisions are based on scope, scientific quality, methodological rigor, ethical compliance, reporting quality, and relevance to the journal.
The article processing charge of USD 2,100 becomes payable only after a manuscript has been accepted. Accepted articles are published open access under CC BY 4.0, and authors retain copyright.
