  • 2023. 02. 28 12th version

Annals of Coloproctology (Ann Coloproctol, ACP) is the official journal of the Korean Society of Coloproctology (KSCP) and the Asia Pacific Federation of Coloproctology (APFCP). ACP was launched in 1985 and was designated as the official journal of APFCP in 2019.

As an international, peer-reviewed, open access journal, ACP aims to contribute to the in-depth development, cure of colorectal diseases, and improvement of public health. The scope of ACP includes basic and clinical research in colorectal surgery, physiology, epidemiology, and pathophysiology. ACP is mainly interested in surgical issues of diseases originating from the lower digestive system such as colon, rectum, anus, and small bowel. These diseases include colorectal cancer, anal cancer, inflammatory bowel disease, benign colonic disease, anorectal disorders, functional diseases, and pelvic floor disorders. In addition, ACP has a regional focus on Asia but welcomes submissions from researchers worldwide.

Contents of ACP is primarily aimed at doctors, nurses, basic researchers, and other health professionals involved in the management of colorectal disease, including colorectal surgeons, surgical oncologists, medical oncologists, radiation oncologists, colorectal pathologists, radiologists, and gastroenterologists. Its contents are also relevant to researchers and clinicians interested in lower gastrointestinal tract disease. ACP may also be of interest to administrators, policy makers, and students seeking to understand recent trends in the field of colon and rectal issues.

ACP publishes original articles, reviews, technical notes, brief communications, guidelines, editorials, letters to the editor, and videos related to the field of coloproctology. ACP is published bimonthly on the last day of February, April, June, August, October, and December.

Manuscripts for submission to ACP should be prepared according to the following instructions. ACP follows the Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly work in Medical Journals ( from the International Committee of Medical Journal Editors (ICMJE).

Table of Contents


Accepted manuscripts are published with the understanding that the author(s) will cover the costs of publication, including page charges. The basic page charge for published manuscripts is USD 500. Any photographs, electron micrographs, color plates, and other special illustrations will also be reproduced at the author’s expense at cost prices.

ACP offers waivers and discounts for authors based in low-income countries as classified by the World Bank ( as of July in the year prior to submission. Requests for waivers should be made at the time of submission. Please contact the Editorial Office ( to request a waiver. In order to ensure that a paper’s waiver status does not influence the editor’s decision, editors are not informed when a waiver has been granted.


ACP adheres to the guidelines and best practices published by professional organizations, including ICMJE Recommendations (; the Principles of Transparency and Best Practice in Scholarly Publishing (, a joint statement by the Committee on Publication Ethics (COPE), the Directory of Open Access Journals (DOAJ), the World Association of Medical Editors (WAME), and Open Access Scholarly Publishers Association (OASPA); and the Good Publication Practice Guideline for Medical Journals ( Furthermore, all processes of handling research and publication misconduct shall follow the applicable COPE flowchart (

Authorship credit should be based on the 4 ICMJE criteria: (1) substantial contributions to conception and design, acquisition of data, and/or analysis and interpretation of data; (2) drafting the article or revising it critically for important intellectual content; (3) final approval of the version to be published; and (4) agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of it are appropriately investigated and resolved. All authors should meet all 4 criteria. The corresponding author must complete and sign the copyright transfer agreement and conflict of interest disclosure form.
  • • A list of each author’s role and ORCID should accompany the submitted paper.
  • • Correction of authorship: After the initial submission of the manuscript, any changes regarding authorship, such as adding or deleting author(s) or changing the order of authors, must be explained in a letter to the editor from the authors involved. The letter must include the following from the corresponding author: (1) an explanation for the change in authorship and (2) a written confirmation (email or letter) from all authors that they agree with the change in authorship. This letter must be signed by all authors of the paper including the author(s) being added or removed. ACP does not alter authorship after publication unless a mistake has been made by the editorial staff. Any changes will be done in accordance with COPE flowcharts, and a correction may be published as a result.
  • • Contributors: Any researcher who have made substantial contributions to the study in terms of idea development, manuscript writing, conducting research, data analysis, and financial support, but do not meet all 4 ICMJE criteria for authorship, should have their contributions acknowledged in the Acknowledgments section of the article. ACP encourages authors to properly acknowledge the contributions of patients and the public to their research when appropriate.
  • • Role of corresponding author: The corresponding author takes primary responsibility for communication with the journal during the manuscript submission, peer review, and publication process, and typically ensures that all the journal’s administrative requirements, such as providing details of authorship, ethics committee approval, clinical trial registration documentation, and gathering conflict of interest statement forms, are properly completed. The corresponding author should be available throughout the submission and peer review process to respond to editorial queries in a timely manner, and after publication, should be available to respond to critiques of the work and cooperate with any requests from the journal for data or additional information or questions about the article.
  • • Recommendations for working with people with personal connections: Authors who intend to include minors (under the age of 19 years) or their family members (such as spouse, children, or relatives) in their research, including publishing or presenting papers together, should clearly indicate this in the cover letter. For further information, please refer to the Guidelines for Preventing Illegitimate Authorship by the National Research Foundation of Korea (
Originality and duplicate publication
All submitted manuscripts must be original and should not be under consideration for publication by other scientific journals at the same time. Duplication of any part of an accepted manuscript in another scientific journal without the approval of the Editorial Board is strictly prohibited. If any instances of duplicate publication are discovered, the authors will be publicly acknowledged in the journal, their affiliated institutions will be notified, and appropriate penalties will be imposed on the authors.
Secondary publication
Manuscripts may be republished if they satisfy the conditions for secondary publication outlined by the ICMJE Recommendations (
Conflict of interest
A conflict of interest exists when an author (or the author’s institution), reviewer, or editor has financial or personal relationships that inappropriately influence (bias) their actions (such relationships are also known as dual commitments, competing interests, or competing loyalties). These relationships vary from being negligible to having great potential for influencing judgment. Not all relationships represent true conflicts of interest. Nevertheless, the potential for a conflict of interest can exist regardless of whether an individual believes that the relationship affects their scientific judgment. Financial relationships (such as employment, consultancies, stock ownership, honorarium, and paid expert testimony) are the most easily identifiable conflicts of interest and the most likely to undermine the credibility of the journal, the authors, and science itself. However, conflicts can also occur from personal relationships, academic competition, or intellectual passion. Conflicts of interest may also arise during the research process; however, the important point is the disclosure itself ( To ensure the credibility of the journal and the authors, it is essential that all conflicts of interest are disclosed. If there are any conflicts of interest, authors should inform the editor and disclose them in the manuscript. In particular, all sources of funding applicable to the study should be explicitly stated. Disclosing conflicts of interest allows editors, reviewers, and readers to approach the manuscript with an understanding of the situation under which the research work was performed.
Statement of human and animal rights
Clinical research should be conducted in accordance with the World Medical Association (WMA) Declaration of Helsinki: Medical Research Involving Human Subjects ( Clinical studies that do not meet the Declaration of Helsinki will not be considered for publication. All clinical studies involving human participants should include a certificate, agreement, or approval from the Institutional Review Board (IRB). For clinical studies with animal subjects, there should be a certificate, agreement, or approval from the Institutional Animal Care and Use Committee (IACUC). ACP will not consider any studies involving humans or animals without appropriate approval. If necessary, the editor or reviewers may request copies of these documents to resolve questions about IRB/IACUC approval and study conduct. For human subjects, identifiable information such as names, initials, hospital numbers, dates of birth, or other protected healthcare information should not be disclosed. For animal subjects, research should adhere to the guidelines outlined in the National or Institutional Guide for the Care and Use of Laboratory Animals and must be performed with ethical consideration for all experimental animals.
Statement of informed consent
Informed consent should be obtained from patients who participated in the clinical investigations, unless waived by the IRB. Copies of written informed consents should be kept for studies involving human subjects. Images of human subjects should only be used if the information is essential for scientific purposes and explicit permission has been obtained as part of the consent. Even with consent, identifying details should be omitted if they are not necessary. Authors must ensure that any alterations made to maintain the anonymity of individuals in photographs do not compromise the scientific accuracy of the image. If consent has not been obtained, it is generally not sufficient to anonymize a photograph simply by using eye bars or blurring the face of the individual concerned.
Registration of clinical trial research
Any research involving clinical trials should be registered with the primary national clinical trial registry site, such as the Korea Clinical Research Information Service (CRIS;, a primary national registry site accredited by the World Health Organization (, or (, a service of the US National Institutes of Health.
Description of participants
Ensure correct use of the terms “sex” (when reporting biological factors) and “gender” (when reporting identity, psychosocial, or cultural factors). Unless inappropriate, the sex and/or gender of study participants, animals, or cells should be reported, and the methods used to determine them should be described. If the study was conduced exclusively in one population, such as one sex, the authors should provide justification for the exclusion of the other population, unless it is obvious (e.g., in the case of prostate cancer). The method used to determine race or ethnicity and its relevance should also be defined by the authors.
Management of research and publication misconduct
In case the journal encounters suspected cases of research and publication misconduct, such as redundant (duplicate) publication, plagiarism, fraudulent or fabricated data, changes in authorship, an undisclosed conflict of interest, ethical problems with a submitted manuscript, a reviewer who has appropriated an author’s idea or data, complaints against editors, and so on, the resolution process will follow the flowchart provided by COPE ( The discussion and decision on the suspected cases are carried out by the Editorial Board in accordance with the Regulations of the Research Ethics Council.
Editorial responsibilities
The Editorial Board is committed to maintaining high standards of publication ethics and will continuously work towards this goal by providing guidelines for retracting articles; preserving the integrity of academic record; prioritizing intellectual and ethical standards over commercial interests; publishing corrections, clarifications, retractions and apologies when necessary; and preventing plagiarism and fraudulent data. The responsibilities of editors include the authority to accept or reject articles; ensuring that there is no conflict of interest with regards to the articles they accept or reject; promoting the publication of corrections or retractions when errors are discovered; and preserving the anonymity of reviewers.


The copyrights for all published materials of ACP are owned by KSCP. The corresponding author must sign and submit the copyright transfer agreement form upon submission. The paper will not be published until the copyright transfer is complete. Permission must be obtained from KSCP for any commercial use of the materials.
Open access policy
ACP is an open access journal distributed under the terms of the Creative Commons Attribution Non-Commercial License (, which permits unrestricted use, distribution, and reproduction in any medium, as long as the original work is properly cited. All contents of the journal are immediately available upon publication without an embargo period.
Authors who wish to reproduce tables or figures published in ACP for scholarly and educational purposes do not need to obtain permission. This is in accordance with the Budapest Open Access Initiative definition of open access and the open access policy of US National Library of Medicine (NLM)’s PubMed Central ( However, proper acknowledgment must be given for the reuse of any borrowed material, by including a footnote on the reproduced table or in the figure legend (e.g., “Reprinted from Ann Coloproctol Year;Vol:Page, available under the Creative Commons License.”) and in the reference list.
Authors who wish to reproduce tables or figures published in ACP for commercial uses must obtain permission. Commercial use refers to any type of reuse for commercial benefit to the user, their place of employment, another entity. Examples of commercial use include (1) reuse by a non-authors, third parties, or other publishers of parts of or all of an article or articles in another publication (journal or book) for sale; (2) systematic distribution of multiple print or electronic copies of items taken from the journal to third parties for marketing purposes; and (3) reuse by an author of portions or all of an article in other publications from commercial organizations.
Article sharing (author self-archiving) policy
ACP is an open access journal, which allows authors to freely share their research in various ways, such as preprint servers, social media platforms, conferences, and educational materials, in accordance with our open access policy. However, authors are strictly prohibited from submitting the same manuscript to multiple journals.
Data sharing policy
ACP encourages data sharing wherever possible, unless this is prevented by ethical, privacy, or confidentiality matters. Authors wishing to do so may deposit their data in a publicly accessible repository and include a link to the DOI within the text of the manuscripts.
ACP accepts the ICMJE Recommendations for data sharing statement policy on clinical trials ( Authors may also refer to the editorial, “Data Sharing statements for Clinical Trials: A Requirement of the International Committee of Medical Journal Editors,” in the Journal of Korean Medical Science vol. 32, no. 7, p. 1051–3 (
Archiving policy
The full text of ACP has been archived in PubMed Central ( and the National Library of Korea ( since 2010 (from the 26th volume). ACP ensures the long-term availability of its contents, even if the journal is no longer in publication, through archiving in PubMed Central, Korea Citation Index (, and the National Library of Korea.
Preprint policy
ACP allows authors to submit preprints to the journal. A preprint refers to a version of a scholarly paper that precedes formal peer review and publication in a peer-reviewed scholarly journal. Submitting a preprint to ACP will not be considered as duplicate submission or publication. ACP advises authors to mention the existence of the preprint, along with its DOI, in the cover letter during the submission process. Failure to do so may result in a plagiarism check program (Similarity Check) flagging the submission for excessive duplication. The preprint will go through the same peer review process as any other submission. If accepted for publication, the authors are encouraged to update the preprint with a link to the published article in ACP, including the DOI. It is highly recommended that authors cite the published article in ACP instead of the preprint in their future submissions to other journals.
Peer review policy
All papers, including those invited by the editor, are subject to a rigorous peer review process. ACP follows a double-blind peer review policy, in which the identities of both the authors and reviewers are kept anonymous throughout the review process. However, the editor managing the review process will have visibility of the authors and reviewers’ identities. The Editorial Board selects reviewers based on expertise, publication history, and past reviews. During the peer review process, reviewers can interact directly or exchange information (e.g., via submission systems or email) with only the editor, which is known as “independent review.” The editor is responsible for the final decision on whether to accept or reject a manuscript. An initial decision is typically made within 4 to 8 weeks of receipt of the manuscript. The review process and editorial decision are not published on the article page.


  • • Online submission: Manuscripts are directly submitted to ACP via the journal’s submission page ( Once you have registered and logged into your account, the online system will lead you through the steps of the submission process. All articles submitted to the journal must comply with the instructions. Failure to do so will result in the return of manuscript and possible delay in publication. For assistance, please contact the Editorial Office (email:, tel: +82-2-2040-7747).
  • • Author’s checklist: You will first be requested to complete the Author Checklist ( Before submitting a new manuscript, please ensure that every point listed in the Author Checklist has been addressed.
  • • Document forms: Before logging into the online submission system, you should prepare the following documents, which you will be asked to upload during electronic submission:
    • - Copyright transfer agreement and conflict of interest disclosure form
    • - Cover letter: A cover letter must be included, indicating the address and email address of the corresponding author.
    • - English proofreading (nonobligatory): Authors may choose to provide a certificate verifying that their manuscript has been edited by an English proofreading service.
Peer review process
  • • Review process: ACP reviews all received manuscripts. A manuscript is first reviewed for its format and then sent to a minimum of 2 independent expert reviewers of the field to assess the quality of the paper. If deemed necessary, a review of statistics may be requested. Authors’ names and affiliations are removed during peer review. The acceptance criteria for all papers are based on the quality and originality of the research and its clinical and scientific significance. The decision to accept or reject a manuscript is based on the critiques and recommended decisions of the reviewers. An initial decision will normally be made within 4 weeks of receiving a manuscript, and reviewers’ comments are sent by email to the corresponding author. Revised manuscripts must be submitted online by the corresponding author. The corresponding author must indicate, item-by-item, the alterations that have been made in response to each of the reviewers’ comments. Failure to resubmit the revised manuscript within 8 weeks of the editorial decision is regarded as a withdrawal. A final decision on acceptance or rejection for publication is forwarded to the corresponding author by the Editorial Office. Certain publication types, including editorials, errata, corrigenda, retractions, withdrawals, and letters to the editor, are reviewed by the Editorial Board without external peer review.
  • • Appeals of decisions: Any appeal against an editorial decision must be made within 2 weeks of the date of the decision letter. Authors who wish to appeal a decision should contact the Editor-in-Chief, explaining in detail their reasons for their appeal. All appeals will be discussed with at least 1 other associate editor. If consensus cannot be reached thereby, an appeal will be discussed at a full editorial meeting. The process of handling complaints and appeals follows the guidelines of COPE ( ACP does not consider second appeals.


ACP focuses on original articles containing clinical and experimental studies, editorials, brief communications, technical notes, letters to the editor, video, invited review articles, and guidelines. Effective July 2023, ACP no longer accepts case report submissions. Any physicians or researchers throughout the world can submit a manuscript provided its scope is appropriate. Manuscripts should be submitted in English. Medical terminology should be written in accordance with the most recent edition of Dorland’s Illustrated Medical Dictionary.

It should have a minimum width of 107 mm and a minimum resolution of 300 dpi for color figures, 500 dpi for black-and-white figures, and 1,000 dpi for line art figures. It is recommended that the 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 1-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 free-access journal for using tables or figures published therein. Examples are shown in the following: “Reprinted (Modified) from Tanaka et al. [48], with permission of Elsevier.” OR “Reprinted (Modified) from Weiss et al. [2], in accordance with the Creative Commons License.

TIFF and PDF 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 defined 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.
Galley 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 the 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 the responsibility for the error).
Process after proofreading
After proofreading, the manuscript abstract will appear on the journal homepage and PubMed as an epub ahead of print. The abstract will be replaced with the final version of the full article once the article has been published.
Errata and Corrigenda
To correct errors in published articles, the corresponding author should contact the 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.
