  • Supply files that are too low in resolution;
  • Submit graphics that are disproportionately large for the content.

Please note that the cost of color illustrations will be charged to the author.

4. Disclosure of Conflicts of Interest

The corresponding author must inform the editor of any potential conflicts of interest that could influence the authors interpretation of the data. Examples of potential conflicts of interest are financial support from or connections to pharmaceutical companies, political pressure from interest groups, and academically related issues. Conflict of interest statements will be published at the end of the text of the article, before the 'References' section. Please consult the COPE guidelines (http://www.publicationethics.org/) on conflict of interest. Even when there is no conflict of interest, it should also be stated.

5. Ethical Approval of Studies

For human or animal experimental investigations, appropriate institutional review board or ethics committee approval is required, and such approval should be stated in the methods section of the manuscript. For those investigators who do not have formal ethics review committees, the principles outlined in the Declaration of Helsinki should be followed (World Medical Association Declaration of Helsinki: Ethical Principles for Medical Research Involving Human Subjects. Available at: http://www.wma.net/en/30publications/10policies/b3/ index.html).

6. Redundant Publication or Duplicate Submission

Redundant (or duplicate) publication is publication of a paper that overlaps substantially with one already published in print or electronic media. Submitted manuscripts are considered with the understanding that they have not been published previously in print or electronic format (except in abstract or poster form) and are not under consideration in totality or in part by another publication or electronic medium. For more information, please refer to 'Uniform Requirements for Manuscripts Submitted to Biomedical Journals: Writing and Editing for Biomedical Publication' (Available at: http://www.icmje.org/recommendations/archives/2008_urm.pdf).
For the policies on the research and publication ethics not stated in this instruction, 'Ethical Policies' section of this Journal can be applied.

7. The Editorial and Peer Review Process

As a general rule, the receipt of a manuscript will be acknowledged within 2 weeks of submission; authors will be provided with a manuscript reference number for future correspondence. If an acknowledgment is not received in a reasonable period of time, the author should contact the Editorial Office.
Submissions are reviewed by the Editorial Office to ensure that it contains all parts. Submissions will be rejected if the author has not supplied all the material and documents as outlined in these author instructions.
Manuscripts are then reviewed by the Editors, who make an initial assessment. If the manuscript does not appear to be of sufficient merit or is not appropriate for the Journal, the manuscript will be rejected without review. Rejected manuscripts will not be returned to authors unless requested. All other manuscripts are sent to 2 or more expert consultants for double-blind peer review. Authors will usually be notified within 12 weeks of the initial acknowledgment of whether the manuscript is accepted for publication, rejected, or subject to revision before acceptance. However, do note that delays are sometimes unavoidable.

8. Similarity Check


Similarity Check is a multi-publisher initiative to screen published and submitted content for originality. To find out more about Similarity Check, visit http://www.crossref.org/crosscheck/index.html. All manuscripts submitted to Gastrointestinal Intervention may be screened, using the iThenticate tool, for textual similarity to other previously published works.

9. Copyright

Published manuscripts become the permanent property of the Society of Gastrointestinal Intervention, and must not be published elsewhere without written permission. A copyright transfer form should be downloaded in the submission site and submitted to the editorial office by fax or e-mail containing a scanned copyright transfer form on acceptance.

10. Publication Fees

The publication of article is free of charge, while the authors could be requested to pay actual cost when the special design or reprinting is necessary.
