Guidance for Authors on the Preparation and Submission of Manuscripts to the Journal of Gastrointestinal and Liver Diseases

Scope: The manuscripts submitted for publication should report original clinical and scientific human research, which contributes to the advancement of knowledge in the field of gastroenterology and hepatology. The field comprises prevention, diagnosis and management of gastrointestinal and hepatobiliary disorders, as well as related molecular genetics, pathophysiology, and epidemiology.

We process manuscripts of clinical gastroenterology.

Due to limited space:

We do not publish animal experimental studies.  

We do not accept for evaluation papers related to basic research,  pediatric pathology or to surgical techniques.


The Journal of Gastrointestinal and Liver Diseases is published quarterly.
Submission and procession of manuscripts is free of charge for authors.
Only manuscripts in English language will be accepted.
Submitting a scientific paper for publication is subject to the fulfillment of the following statements:

– the paper does not infringe upon any copyright or other proprietary right;
– the manuscript has been reviewed and approved by all named authors;
If your paper contains studies on humans, you must insert in the ”Methods” section a statement mentioning the approval of the medical ethical commission of the organization in which the study was realized.

Informed consent
Please send copies of patients᾽ consent forms in which patients or relatives in case the patient cannot, or other subjects of your experiments clearly grant permission for inclusion in the study and/or the publication of photographs or other material that might identify them.
Please note that Journal of Gastrointestinal and Liver Diseases is a member of COPE (Committee on Publication Ethics) and failure to comply with their guidelines may lead to the rejection of the manuscript.

Title Page
The authors will prepare a separate Title Page file in Microsoft Word format, containing:
- article type (Editorial, Original Article, Review Article, Systematic Review, Meta-Analyse, Case Report, Letter to the Editor)
- full title of the article - in sentence case,
- short title
- words count (excluding abstract, acknowledgement, figure legends, and references)

- the corresponding author contact details (*Correspondence: name, email address),
- conflict of interest statement for each author,
- acknowledgements,
- the Authors' contributions (see below). Authors' contributions. The International Committee of Medical Journal Editors Recommendations consider that authorship is based on the following four criteria:"Substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data for the work; AND

Drafting the work or revising it critically for important intellectual content; AND
Final approval of the version to be published; AND
Agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved." Please specify each author’s contribution to the paper in the Title Page file, using the words describing your contribution mentioned above, and making sure all four criteria are fulfilled. Besides the words specified above you can use other words detailing and clarifying better each author contribution. (e.g. Authors' contributions S.H. the concept and design of the study; A.A, T.D., and D.A. data acquisition; T.J. statistical analysis; K.W. performed the DNA extraction and genotyping in the laboratory, interpreted the results; T.M. analyzed the data and drafted the manuscript. All authors critically revised the manuscript, approved the final version to be published, and agree to be accountable for all aspects of the work.) We recommend an ethical attribution of authorship and do not recommend formulations like: "both authors" or "all authors" equally contributed except really sensational manuscripts. Senior authors should always be mentors or head of units. We do not recommend sharing of seniority in the same manuscript.

Specific recommendations
The manuscripts should be written according to the following reporting guidelines:  for observational studies, the STROBE statement; for clinical trials, the CONSORT statement; for diagnostic studies, the STARD statement; for systematic reviews, the PRISMA statement; for clinical cases, the CARE statement. Other reporting guidelines may also be used if they are more appropriate to your study, then the ones listed before (see

Peer-review procedure
The Editor-in-chief or one of the editors first reads the manuscripts received and decides upon their priority level: some are immediately sent to the reviewers, some are rejected without being sent for review and some are returned to authors with suggestions for improvement before submitting them to reviewers. Manuscripts will be checked for plagiarism using the
All original papers are anonymously reviewed by two or three independent reviewers. The reviewers send their comments to the Editor. The Editor will inform the authors about the suggestions made by the referee and ask them to answer the questions and make the required corrections.
The revised manuscript should be returned in no more than two months to the Editor. When the Editor receives the corrected version with all changes marked, accompanied by the reply letter to the reviewers, he sends those back to the same reviewers, who make the final recommendation for acceptance or rejection of the manuscript. The Editor’s decision is final and will not be subject of further correspondence for manuscripts considered unsuitable for publication.

Open access
All original articles, reviews, editorials and case reports published in the journal are available online for all to read and use free of charge.
