Reporting guidelines for specific study designs
For specific study designs, such as randomized control studies, studies of diagnostic accuracy, meta-analyses, observational studies, and nonrandomized studies, authors are encouraged to also consult the reporting guidelines relevant to their specific research design. A good source of reporting guidelines is the EQUATOR Network ( and the NLM (
Original articles report basic or clinical investigations. Although there is no limitation on the length of these manuscripts, the Editorial Board may abridge excessive illustrations and large tables. An original article manuscript should be organized in the following sequence: title page; abstract and keywords; main text (introduction, methods, results, and discussion); acknowledgments; references; tables; figure legends; and figures.
The cover letter should confirm that neither the submitted material nor portions thereof have been published previously or are under consideration for publication elsewhere. It should also state any potential conflict of interest that could influence the authors’ interpretation of the data, such as financial support from or connections to pharmaceutical companies, political pressure from interest groups, or academically related issues.
  • Title page: Include the following items on the title page: the paper’s title, the name of the authors, and the name of their current affiliation. If the author’s affiliation is different, then separate it with a semicolon according to the author’s order. For authors with different affiliations, the authors should be marked “1,” “2,” “3,” and so forth in Arabic numerals, which should appear in superscript at the top-right-hand corner of the author’s name and before the affiliation. At the bottom of the title page, write the principal author’s address, phone, fax, and e-mail address, and, if necessary, state the source of any research funding.
  • Abstract and Keywords: The abstract should be concise, containing no more than 250 words, and describe, using a structured format, the purpose, methods, results, and conclusion of the study. Up to 5 keywords should be listed immediately below the abstract to be used as index terms. We strongly recommend using Medical Subject Headings (MeSH) keywords (
  • Introduction: Briefly describe the purpose of the investigation, including relevant background information.
  • Methods: Describe, in the following order, the research plan, materials (or subjects), and methods used. Explain, in detail, how the disease was confirmed and how subjectivity in observations was controlled. When an experimental methodology is the paper’s main focus, describe the process in detail so as to recreate the experiment as closely as possible. The sources of special chemicals or reagents should be given, along with the source location (company name, city, state/province, and country). Methods of statistical analysis and criteria for statistical significance should be described. Studies performed using clinical samples or data, and those involving animals, must include information on the IRB/ethics committee approval or waiver and informed consent. An example is shown below.
    “We conducted this study in compliance with the principles of the Declaration of Helsinki. The study’s protocol was reviewed and approved by the Institutional Review Board of OO (IRB No. OO). Written informed consents were obtained / Informed consent was waived.”
  • Results: The results should be presented in a logical sequence in the text. Tables and illustrations and repetitively present the same data in different forms should be avoided. The results should not include material appropriate to the discussion.
  • Discussion: Observations pertaining to the results of research and other related materials should be interpreted for your readers. Emphasize new and important observations; do not merely repeat the contents of the results. Explain your interpretation of the observations, along with the limits of their application; connect any conclusions to the purpose of the research. In a concluding paragraph, summarize the results and what they mean.
  • Acknowledgments: All persons who have made substantial contributions, but not met the criteria for authorship, are acknowledged here. All sources of funding applicable to the study should be explicitly stated here.
  • References: In the text, references should be cited with Arabic numerals in brackets, numbered in the order cited. In the references section, the references should be numbered and listed in order of appearance in the text. List all authors for sources with no more than 6 authors; if there are more than 6, list the first 6 authors followed by “et al.” If an article has been published online, but not yet assigned an issue or page numbers, the digital object identifier (DOI) should be supplied. Journal titles should be abbreviated following the MEDLINE style. Other types of references not described below should follow the NLM’s “Samples of Formatted References for Authors of Journal Articles” ( The number of references is limited to 30 for original article.

  • Tables: Tables must be numbered in the order in which they are cited in the text. A table’s caption, to be placed immediately above the table, should concisely describe its contents to enable a reader to understand the table without referring to the text. Each table must be simple and typed on a separate page. Explanatory matter is placed in footnotes below the tabular matter, and not included in the caption. All nonstandard abbreviations are also explained in the footnotes. Footnotes should be indicated by superscript a, b, c, d, etc. Statistical measures, such as SD or SE, should be identified. Vertical rules and horizontal rules between entries should be omitted.
  • Figures: Upload each figure as a single image file in either uncompressed TIFF, PNG, EPS, PDF, or PPT format, with a resolution of at least 600 dpi (dots per inch). It is recommended that drawings and pictures should be in full color. For multiple prints bearing the same figure number, use English letters after numerals to indicate the correct order: e.g., Fig. 1A --, Fig. 1B. Figures should be numbered, using Arabic numerals, in the order in which they are cited. A figure caption should be a one-sentence description, rather than a phrase or a paragraph.

    If any tables or figures are taken or modified from other papers, authors should obtain permission through the Copyright Clearance Center ( or from the individual publisher, except where the materials concerned have been published in an open access journal under the Creative Commons license. For tables or figures from an open access journal, simply verify the source of the journal precisely in the accompanying footnote. Please note the distinction between a free-access journal and an open access journal: it is necessary to obtain permission from the publisher of a freeaccess journal for using tables or figures published therein. Examples are shown below:
    Reprinted (Modified) from Tanaka et al. [48], with permission of Elsevier. OR
    Reprinted (Modified) from Weiss et al. [2], according to the Creative Commons License of OA Publishing London.
  • Video submission: Video clips can be submitted for placement on the journal’s website. All videos are subject to peer review and must be sent directly to the Editor by e-mail. A video file submitted for consideration for publication should be in complete and final format, and at as high a resolution as possible. Any editing of the video will be the responsibility of the author(s). Video files should not exceed 30MB and 5 minutes in duration. We accept all formats of video files, but recommend QuickTime, AVI, MPEG, and RealMedia files. A legend to accompany the video should be double-spaced in a separate file. A still image from the video should be indicated for use in print or on a nonanimated webpage to link to the video. After acceptance for publication of the paper to which any video file relates, all copyrights in the video file are automatically transferred to Annals of Coloproctology.
Case reports will be published only in exceptional circumstances, namely when they illustrate a rare occurrence of clinical importance. Case reports should address issues of importance to medical researchers and should preferably contain helpful illustrations. A case report manuscript should be organized in the following sequence: title page; abstract and keywords; main text (introduction, case report, and discussion); acknowledgments; references; tables; figure legends; and figures. The abstract should be unstructured and not exceed 150 words. There should be no more than 5 figures, including tables, and no more than 15 references.
Reviews are invited by the editor and should be comprehensive analyses of specific topics. They are organized as follows: title page; abstract and keywords; main text (introduction, body text, and conclusion); acknowledgments; references; tables; figure legends; and figures. There should be an unstructured abstract of no more than 200 words. The length of the text, excluding references, tables, and figures, should not exceed 7,500 words. The number of references is limited to 100 for review article.
Editorials are invited by the editor and should be commentaries on articles published recently in the journal. Editorial topics could include active areas of research, fresh insights, and debates in all fields of coloproctology. Editorials should not exceed 2,000 words, excluding references, tables, and figures.
Letters to the editor should include brief important comments, useful to readers, concerning previously published articles in the journal. They should not exceed 1,000 words and up to 10 references. The Editorial Board reserves the right to edit letters to the editor and decide whether they should be accepted or rejected for publication.


Final version
After a paper has been accepted for publication, the author(s) should submit the final version of the manuscript. The names and affiliations of authors should be double-checked, and if the originally submitted image files were of poor resolution, higher resolution image files should be submitted at this time. TIFF, PNG, EPS, PDF, or PPT formats are preferred for submission of digital files of photographic images. Symbols (e.g., circles, triangles, squares), letters (e.g., words, abbreviations), and numbers should be large enough to be legible on reduction to the journal’s column widths. All symbols must be de fined in the figure caption. If references, tables, or figures are moved, added, or deleted during the revision process, renumber them to reflect such changes so that all tables, references, and figures are cited in numeric order.
Manuscript corrections
Before publication, the manuscript editor will correct the manuscript such that it meets the standard publication format. The author(s) must respond within 2 working days when the manuscript editor contacts the author for revisions. If the response is delayed, the manuscript’s publication may be postponed to the next issue.
Gallery proof
The author(s) will receive the final version of the manuscript as a PDF file. Within 2 working days of receipt, authors must notify the Editorial Office (or printing office) of any errors found in the file. Any errors found after this time are the responsibility of the author(s) and will have to be corrected as errata or corrigenda (depending on responsibility for the error).
Errata and Corrigenda
To correct errors in published articles, the corresponding author should contact the journal’s Editorial Office with a detailed description of the proposed correction. Corrections that profoundly affect the interpretation or conclusions of the article will be reviewed by the editors. Corrections will be published as corrigenda (corrections of author’s errors) or errata (corrections of publisher’s errors) in a later issue of the journal.


Accepted manuscripts are published on the implicit understanding that the author(s) will pay the costs of publication, including page charges. The basic page charge for the article is KRW 300,000 for all published manuscripts. Illustrations, photographs, electron micrographs, color plates, and other special illustrations will be reproduced at the author’s expense at cost prices.
