Instructions for Authors

Scope and Aim

Journal of the Anus, Rectum and Colon (JARC) is the official peer-reviewed and open-access journal of the Japan Society of Coloproctology. The Journal’s aim is to advance knowledge of coloproctology-related studies, and to promote the standards in research and conduct of physicians, surgeons, proctologists and all other professionals engaged in the field of coloproctology worldwide. The journal publishes original research articles, review articles, practice guidelines, clinical research, case reports, “How I do it”, and letters to the editor.

Peer Review System

All submitted manuscripts will be reviewed by an editor of JARC to evaluate the eligibility for possible publication. Thereafter, the manuscripts will be sent to two to three expert reviewers in the field of the study for peer review.

Reviewers are not allowed to contact authors directly before, during, or after the reviewing process to discuss any information that is presented in the manuscripts. Reviewers must keep the manuscripts and information obtained strictly confidential and must not publicly discuss or disclose the contents and any other information of the manuscripts to a third party.

Preparation of Manuscript

Articles that have been previously published, or are being considered for publication in another journal, in any languages, will not be accepted. The Editorial Committee makes decisions on acceptance of the peer-reviewed manuscripts.

The current information is based in part on “Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly work in Medical Journals” as published by the International Committee of Medical Journal Editors (ICMJE). For any information that is not mentioned in these guidelines, authors should refer to the ICMJE Recommendations, which are available at

If authors are non-native speakers of English, their manuscript must be edited by a native English speaker who is specialized in medical editing prior to submission.

Article Types

Submitted articles should be categorized into one of the following categories.

a) Original Research Articles:
Original research articles include manuscripts that encompass the broad range of innovative and impactful clinical and basic research in the field of coloproctology.
b) Review Articles:
Review articles should provide a comprehensive and scholarly account of a topic that has direct relevance to coloproctology.
c) Practice Guidelines:
Practice guidelines are statements that include recommendations intended to optimize patient care that are informed by a systematic review of evidence and an assessment of the benefits and harms of alternative care options.
d) Clinical Research:
Clinical research should describe the purpose, design, methods, results and conclusion of a research and its clinical implications.
e) Case Reports:
Case reports that show originality or have educational implications for diagnosis and treatment are welcomed. Authors should be aware that the Journal publishes only a few case reports per issue.
f) How I Do It:
“How I do it” should be brief descriptions of a new method or technique.
g) Letters to the Editor:
Letters to the editor are brief, constructive commentaries that can be submitted in response to a recently published article in the Journal.

Manuscript Submission

Submit manuscripts electronically via ScholarOne system: in the following order: Title page, main document, tables and figures. The total size of the uploaded files should be within 100 MB.


All authors listed in the manuscript must meet the following criteria of contribution described by the ICMJE in the Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly work in Medical Journals.
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.

The corresponding author must ensure that a manuscript is read and approved by all authors prior to submission.

Contributors who do not meet the criteria mentioned above should not be listed as authors. Guest or honorary authorship is not permitted.

Those who do not qualify for an authorship may be acknowledged individually or together as a group under a single heading with “Acknowledgment” at the end of the manuscript. Examples of activities that do not qualify a contributor for authorship are acquisition of funding; general supervision of a research group or general administrative support; and writing assistance, technical editing, language editing, and proofreading.

Final author order must be established by the end of the revision phase of the peer review process. Adding, deleting or changing the authors’ names and their order is not permitted after the acceptance of the manuscript for publication.

Ethical Considerations

  • Clinical research included in articles, which reports on human subjects, must comply with the provisions of the Declaration of Helsinki, and that the study had been approved by the relevant institutional or national review board. If no approval from any review board was required, it must be explicitly stated in the manuscript.
    The corresponding author must complete Ethical Review Application Checklist for Submission of Academic Papers and upload the checklist to the submission system as “Checklist”. The form is available here.
  • All case studies must clearly indicate that the written consent has been obtained from all patients and relevant persons (such as guardian and family members of the patient) to publish the information, including photographs.
  • Any data or information, such as patient names, initials, hospital patient identification codes (patient ID), specific dates, or any other information, which may identify patients must not be presented anywhere in the manuscript including the figures and tables. All pictures should focus on the affected areas only.
  • Articles reporting on research on human subjects must indicate in the “Materials and Methods” section that the research was approved by the ethics committee of the authors’ affiliated institutions and that the informed consent has been obtained from patients.
  • Articles reporting on data from animal testing must indicate in the “Subjects and Methods” section approval of the testing design by the affiliated institution’s Animal Care and Use Committee.
  • Authors of articles reporting on new DNA sequences must furnish data to the Gene Bank and include the access number for that data in the article.
