Instructions to Authors
Aims and Scope
The journal publishes Case Reports and Clinical Reviews on all aspects of the digestive tract, liver, biliary tract, and pancreas. Critical Case Reports that show originality or have educational implications for diagnosis and treatment are especially encouraged for submission. Systematic and personal reviews of clinical gastroenterology are also welcomed. The journal aims for quick publication of such critical Case Reports and Clinical Reviews.
Prerequisites for Publication
The editors of the Clinical Journal of Gastroenterology abide by the recommendations formulated by the International Committee of Medical Journal Editors (http://www.icmje.org/). A Certificate of Exclusive Submission and Disclosure of Conflict of Interest, available on-line at http://www.springer.com/12328, must be submitted to the journal’s editorial office by uploading it as a PDF via Editorial Manager.
The Disclosure Form, available online (http://www.springer.com/12328), must be uploaded at the time of submission. When your manuscript is accepted for publication, all the statements in the Disclosure Form (Conflict of Interest, Human Rights, and Informed Consent) will be inserted between the Acknowledgement and Reference section in the article.
The editors reserve the right to reject manuscripts that do not comply with the above-mentioned requirements. The author will be held responsible for false statements or failure to fulfill the above-mentioned requirements.
IMPORTANT: Upon receipt of a Certificate of Exclusive Submission and Disclosure of Conflict of Interest with all of the authors’ signatures and Disclosure Form, manuscripts are officially recognized as submissions.
Disclosed Potential Conflict of Interest
When submitting a manuscript to the Clinical Journal of Gastroenterology, all authors are required to disclose any financial relationship within the last 2 years with biotechnology manufacturer, a pharmaceutical company, or other commercial entity that has any interest in the subject matter, materials, or process(es) discussed in the manuscript.
The matters requiring disclosure are outlined in the JSGE Conflict of Interest Policy, available on-line at http://www.jsge.or.jp/english/journal (IV. Matters for disclosure)
If you, your spouse, or other immediate family member has any of the listed relationships with a commercial entity that has an interest in the subject matter in your manuscript, please refer to the JSGE's definition of potential conflicts of interest that must be disclosed.
Studies involving human subjects must include a statement to the effect that all human studies have been performed in accordance with the ethical standards laid down in the 1964 Declaration of Helsinki and its subsequent amendments. If there is any doubt as to whether the research was conducted in accordance with the Helsinki Declaration, the authors must explain the rationale for their approach.
This statement should be declared in the Disclosure Form and submitted with your manuscript.
It should be stated clearly in the text that all subjects gave their informed consent prior to their inclusion in the study. Personally identifiable information on patients or human subjects, including names, initials, addresses, admission dates, hospital numbers, or any other data that might identify patients should not be published in written descriptions, photographs, or histories unless the information is essential for scientific purposes and the patient (or parent / guardian) gives written informed consent for publication. This statement should be declared in the Disclosure Form and submitted with your manuscript. If your manuscript is a Clinical Review and does not apply to obtaining Informed Consent, the following sentence should be added in the Disclosure Form.
• This study does not contain identifying information of the patients.
If consent cannot be obtained because the patient is dead, the authors must seek permission from a relative. If the patient (or parent / guardian) cannot be traced, then publication will only be possible if the information can be sufficiently anonymized and with the editor’s consent.
If any identifiable information concerning patients is included in the article, the following sentence should also be included in the relevant section of the Disclosure Form:
• Additional informed consent was obtained from all patients for which identifying information is included in this article.
Submission of a manuscript implies: that the work described has not been published before; that it is not under consideration for publication anywhere else; that its publication has been approved by all co-authors, if any, as well as by the responsible authorities – tacitly or explicitly – at the institute where the work has been carried out. The publisher will not be held legally responsible should there be any claims for compensation.
Authors wishing to include figures, tables, or text passages that have already been published elsewhere are required to obtain permission from the copyright owner(s) for both the print and online format. (and to include evidence that such permission has been granted when submitting their papers.)

Types of papers
The journal publishes only case reports and clinical reviews, not original research papers.
- Clinical Reviews
Systematic and personal reviews on clinical gastroenterology are welcomed.
Clinical Reviews should include at least one Figure or Table.
- Case Report
Critical Case Reports that show originality or have educational implications for diagnosis and treatment are welcomed. Case Reports should consist simply of the following four sections; Introduction, Case Report (including Figures and Tables, as necessary), Discussion and References.
A manuscript should not include more than 3 cases per submission.
- Letters to the Editor
The Clinical Journal of Gastroenterology welcomes letters to the editor, provided they are related to previously published articles in this journal, and in such cases a copy of the letter will be sent to the previous article’s author(s) to invite a response.
• Word limit: not more than 500 words (including references)
• Figures/Tables: not accepted
The authors are strongly recommended to provide supporting data in tables or figures.
Please be sure to supply figures or data especially relevant to the understanding and interpretation of your manuscript, e.g. endoscopic findings, pathological specimens, etc.
Manuscripts should be submitted in Word.
• Use a normal, plain font (e.g., 10-point Times Roman) for text.
• Use italics only for emphasis.
• Use the automatic page numbering function to number the pages.
• Do not use field functions.
• Use tab stops or other commands for indents, not the space bar.
• Use the table function, not spreadsheets, to make tables.
• Use the equation editor or MathType for equations.
Note: If you use Word 2007, do not create the equations with the default equation editor but use the Microsoft equation editor or MathType instead.
• Save your file in doc format. Do not submit docx files.
The documents should be uploaded in Microsoft Word (.doc) format.
Manuscripts must be typed double-spaced with wide margins. The title page, abstract, key words, text, acknowledgments and references should begin on separate sheets and follow that order. Incomplete or improperly prepared manuscripts will be returned to authors without review.
All manuscripts must be written in English. Authors whose native language is not English should seek the assistance of a colleague who is a native English speaker and is familiar with the field of work.
- Title Page
The title page should include:
• The full name(s) of the author(s)
• A concise and informative title
• The affiliation(s) and address(es) of the author(s)
• The e-mail address, telephone and fax numbers of the corresponding author
Please provide an abstract of not more than 200 words for Case Reports, 250 words for Clinical Reviews.
Please provide 3 to 5 keywords which can be used for indexing purposes.
Standard abbreviations and units should be used. Define abbreviations the first time they are mentioned, and avoid their use in the title and abstract.
Footnotes can be used to give additional information, which may include the citation of a reference included in the reference list. They should not consist solely of a reference citation, and they should never include the bibliographic details of a reference. They should also not contain any figures or tables. Footnotes to the text are numbered consecutively; those to tables should be indicated by superscript lower-case letters (or asterisks for significance values and other statistical data). Footnotes to the title or the authors of the article are not given reference symbols. Always use footnotes instead of endnotes.
The body of the article should be divided into three sections:
The Introduction should state the purpose of the work and provide a concise summary of the rationale for the study or observation.
• Case Report
In the Case Report, detailed description of the case should be presented with the minimum number of tables and illustrations. The originality or educational implication of the case for diagnosis and treatment should be described clearly.
In the Discussion, new and important findings should be discussed with reference to other reported work, and conclusions should be added.
Acknowledgments of people, grants, funds, etc. should be placed in a separate section before the reference list. The names of funding organizations should be written in full.
All contributors who do not meet the criteria for authorship should be listed in an acknowledgments section. Examples of those who might be acknowledged include a person who provided purely technical help, writing assistance, or a department chairperson who provided only general support. Editors should ask corresponding authors to declare whether they had assistance with study design, data collection, data analysis, or manuscript preparation. If such assistance was available, the authors should disclose the identity of the individuals who provided this assistance and the entity that supported it in the published article. Financial and material support should also be acknowledged. Groups of persons who have contributed materially to the paper but whose contributions do not justify authorship may be listed under such headings as “clinical investigators” or “participating investigators,” and their function or contribution should be described—for example, “served as scientific advisors,” “critically reviewed the study proposal,” “collected data,” or “provided and cared for study patients.” Because readers may infer their endorsement of the data and conclusions, these persons must give written permission to be acknowledged.
Reference citations in the text should be identified by numbers in square brackets. Some examples:
1. Negotiation research spans many disciplines .
2. This result was later contradicted by Becker and Seligman .
3. This effect has been widely studied [1-3, 7].
• Reference list
The list of references should only include works that are cited in the text and that have been published or accepted for publication. Accuracy of reference data is the author’s responsibility. Personal communications and unpublished works should only be mentioned in the text. Do not use footnotes or endnotes as a substitute for a reference list. In article citations, list the first three authors only and add “et al.”
The entries in the list should be numbered consecutively.

Ethical Responsibilities of Authors
This journal is committed to upholding the integrity of the scientific record. As a member of the Committee on Publication Ethics (COPE) the journal will follow the COPE guidelines on how to deal with potential acts of misconduct.
Authors should refrain from misrepresenting research results which could damage the trust in the journal, the professionalism of scientific authorship, and ultimately the entire scientific endeavour. Maintaining integrity of the research and its presentation is helped by following the rules of good scientific practice, which include*:
- The manuscript should not be submitted to more than one journal for simultaneous consideration.
- The submitted work should be original and should not have been published elsewhere in any form or language (partially or in full), unless the new work concerns an expansion of previous work. (Please provide transparency on the re-use of material to avoid the concerns about text-recycling (‘self-plagiarism’).
- A single study should not be split up into several parts to increase the quantity of submissions and submitted to various journals or to one journal over time (i.e. ‘salami-slicing/publishing’).
- Concurrent or secondary publication is sometimes justifiable, provided certain conditions are met. Examples include: translations or a manuscript that is intended for a different group of readers.
- Results should be presented clearly, honestly, and without fabrication, falsification or inappropriate data manipulation (including image based manipulation). Authors should adhere to discipline-specific rules for acquiring, selecting and processing data.
- No data, text, or theories by others are presented as if they were the author’s own (‘plagiarism’). Proper acknowledgements to other works must be given (this includes material that is closely copied (near verbatim), summarized and/or paraphrased), quotation marks (to indicate words taken from another source) are used for verbatim copying of material, and permissions secured for material that is copyrighted.
Important note: the journal may use software to screen for plagiarism.
- Authors should make sure they have permissions for the use of software, questionnaires/(web) surveys and scales in their studies (if appropriate).
- Research articles and non-research articles (e.g. Opinion, Review, and Commentary articles) must cite appropriate and relevant literature in support of the claims made. Excessive and inappropriate self-citation or coordinated efforts among several authors to collectively self-cite is strongly discouraged.
- Authors should avoid untrue statements about an entity (who can be an individual person or a company) or descriptions of their behavior or actions that could potentially be seen as personal attacks or allegations about that person.
- Research that may be misapplied to pose a threat to public health or national security should be clearly identified in the manuscript (e.g. dual use of research). Examples include creation of harmful consequences of biological agents or toxins, disruption of immunity of vaccines, unusual hazards in the use of chemicals, weaponization of research/technology (amongst others).
- Authors are strongly advised to ensure the author group, the Corresponding Author, and the order of authors are all correct at submission. Adding and/or deleting authors during the revision stages is generally not permitted, but in some cases may be warranted. Reasons for changes in authorship should be explained in detail. Please note that changes to authorship cannot be made after acceptance of a manuscript.
*All of the above are guidelines and authors need to make sure to respect third parties rights such as copyright and/or moral rights.
Upon request authors should be prepared to send relevant documentation or data in order to verify the validity of the results presented. This could be in the form of raw data, samples, records, etc. Sensitive information in the form of confidential or proprietary data is excluded.
If there is suspicion of misbehavior or alleged fraud the Journal and/or Publisher will carry out an investigation following COPE guidelines. If, after investigation, there are valid concerns, the author(s) concerned will be contacted under their given e-mail address and given an opportunity to address the issue. Depending on the situation, this may result in the Journal’s and/or Publisher’s implementation of the following measures, including, but not limited to:
- If the manuscript is still under consideration, it may be rejected and returned to the author.
- If the article has already been published online, depending on the nature and severity of the infraction:
- an erratum/correction may be placed with the article
- an expression of concern may be placed with the article
- or in severe cases retraction of the article may occur.
The reason will be given in the published erratum/correction, expression of concern or retraction note. Please note that retraction means that the article is maintained on the platform, watermarked “retracted” and the explanation for the retraction is provided in a note linked to the watermarked article.
- The author’s institution may be informed
- A notice of suspected transgression of ethical standards in the peer review system may be included as part of the author’s and article’s bibliographic record.
Authors have an obligation to correct mistakes once they discover a significant error or inaccuracy in their published article. The author(s) is/are requested to contact the journal and explain in what sense the error is impacting the article. A decision on how to correct the literature will depend on the nature of the error. This may be a correction or retraction. The retraction note should provide transparency which parts of the article are impacted by the error.
Suggesting / excluding reviewers
Authors are welcome to suggest suitable reviewers and/or request the exclusion of certain individuals when they submit their manuscripts. When suggesting reviewers, authors should make sure they are totally independent and not connected to the work in any way. It is strongly recommended to suggest a mix of reviewers from different countries and different institutions. When suggesting reviewers, the Corresponding Author must provide an institutional email address for each suggested reviewer, or, if this is not possible to include other means of verifying the identity such as a link to a personal homepage, a link to the publication record or a researcher or author ID in the submission letter. Please note that the Journal may not use the suggestions, but suggestions are appreciated and may help facilitate the peer review process.
These guidelines describe authorship principles and good authorship practices to which prospective authors should adhere to.
The Journal and Publisher assume all authors agreed with the content and that all gave explicit consent to submit and that they obtained consent from the responsible authorities at the institute/organization where the work has been carried out, before the work is submitted.
The Publisher does not prescribe the kinds of contributions that warrant authorship. It is recommended that authors adhere to the guidelines for authorship that are applicable in their specific research field. In absence of specific guidelines it is recommended to adhere to the following guidelines*:
All authors whose names appear on the submission
1) made substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data; or the creation of new software used in the work;
2) drafted the work or revised it critically for important intellectual content;
3) approved the version to be published; and
4) agree 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.
* Based on/adapted from:
Disclosures and declarations
All authors are requested to include information regarding sources of funding, financial or non-financial interests, study-specific approval by the appropriate ethics committee for research involving humans and/or animals, informed consent if the research involved human participants, and a statement on welfare of animals if the research involved animals (as appropriate).
The decision whether such information should be included is not only dependent on the scope of the journal, but also the scope of the article. Work submitted for publication may have implications for public health or general welfare and in those cases it is the responsibility of all authors to include the appropriate disclosures and declarations.
All authors are requested to make sure that all data and materials as well as software application or custom code support their published claims and comply with field standards. Please note that journals may have individual policies on (sharing) research data in concordance with disciplinary norms and expectations. Please check the Instructions for Authors of the Journal that you are submitting to for specific instructions.
Role of the Corresponding Author
One author is assigned as Corresponding Author and acts on behalf of all co-authors and ensures that questions related to the accuracy or integrity of any part of the work are appropriately addressed.
The Corresponding Author is responsible for the following requirements:
- ensuring that all listed authors have approved the manuscript before submission, including the names and order of authors;
- managing all communication between the Journal and all co-authors, before and after publication;*
- providing transparency on re-use of material and mention any unpublished material (for example manuscripts in press) included in the manuscript in a cover letter to the Editor;
- making sure disclosures, declarations and transparency on data statements from all authors are included in the manuscript as appropriate (see above).
* The requirement of managing all communication between the journal and all co-authors during submission and proofing may be delegated to a Contact or Submitting Author. In this case please make sure the Corresponding Author is clearly indicated in the manuscript.
In absence of specific instructions and in research fields where it is possible to describe discrete efforts, the Publisher recommends authors to include contribution statements in the work that specifies the contribution of every author in order to promote transparency. These contributions should be listed at the separate title page.
Examples of such statement(s) are shown below:
• Free text:
All authors contributed to the study conception and design. Material preparation, data collection and analysis were performed by [full name], [full name] and [full name]. The first draft of the manuscript was written by [full name] and all authors commented on previous versions of the manuscript. All authors read and approved the final manuscript.
• Conceptualization: [full name], …; Methodology: [full name], …; Formal analysis and investigation: [full name], …; Writing - original draft preparation: [full name, …]; Writing - review and editing: [full name], …; Funding acquisition: [full name], …; Resources: [full name], …; Supervision: [full name],….
For review articles where discrete statements are less applicable a statement should be included who had the idea for the article, who performed the literature search and data analysis, and who drafted and/or critically revised the work.
For articles that are based primarily on the student’s dissertation or thesis, it is recommended that the student is usually listed as principal author:
The primary affiliation for each author should be the institution where the majority of their work was done. If an author has subsequently moved, the current address may additionally be stated. Addresses will not be updated or changed after publication of the article.
Changes to authorship
Authors are strongly advised to ensure the correct author group, the Corresponding Author, and the order of authors at submission. Changes of authorship by adding or deleting authors, and/or changes in Corresponding Author, and/or changes in the sequence of authors are not accepted after acceptance of a manuscript.
- Please note that author names will be published exactly as they appear on the accepted submission!
Please make sure that the names of all authors are present and correctly spelled, and that addresses and affiliations are current.
Adding and/or deleting authors at revision stage are generally not permitted, but in some cases it may be warranted. Reasons for these changes in authorship should be explained. Approval of the change during revision is at the discretion of the Editor-in-Chief. Please note that journals may have individual policies on adding and/or deleting authors during revision stage.
Authors are recommended to use their ORCID ID when submitting an article for consideration or acquire an ORCID ID via the submission process.
Deceased or incapacitated authors
For cases in which a co-author dies or is incapacitated during the writing, submission, or peer-review process, and the co-authors feel it is appropriate to include the author, co-authors should obtain approval from a (legal) representative which could be a direct relative.
Authorship issues or disputes
In the case of an authorship dispute during peer review or after acceptance and publication, the Journal will not be in a position to investigate or adjudicate. Authors will be asked to resolve the dispute themselves. If they are unable the Journal reserves the right to withdraw a manuscript from the editorial process or in case of a published paper raise the issue with the authors’ institution(s) and abide by its guidelines.
Authors should treat all communication with the Journal as confidential which includes correspondence with direct representatives from the Journal such as Editors-in-Chief and/or Handling Editors and reviewers’ reports unless explicit consent has been received to share information.
