Enactment from October, 1981
Recently revised on February 1, 2024
Clinical Endoscopy (CE) is an open-access and peer-reviewed journal that helps researchers, technicians, and practicing physicians stay up to date on global advances in experimental, diagnostic, and therapeutic endoscopic techniques used in the treatment of disorders of the gastrointestinal and pancreaticobiliary tracts. CE publishes well-structured original articles, state-of-the-art review articles, instructive case reports, image of interest, video of interest, brief reports, and letters to the editor on all subjects in the field of experimental, diagnostic, and therapeutic endoscopy, as well as newer technologies. In addition, the editorials explore challenging issues and encourage debate among physicians on the topics of peptic ulcer disease, inflammatory bowel disease, pancreaticobiliary disease, and gastrointestinal cancer. CE also publishes special issues that feature articles focusing on current practices and the latest advances in equipment and techniques used for the endoscopic management of obesity and disorders of the gastrointestinal and pancreaticobiliary tracts for clinicians who are concerned about the clinical manifestations of these disorders. The journal will try to publish outstanding original articles and reviews as well as articles describing new emerging techniques and practice guidelines. CE is published bimonthly (on the 30th of January, March, May, July, September, and November).
Manuscripts submitted for publication in CE should be prepared according to the instructions. For issues not addressed in these instructions, the author should refer to the Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals (http://www.icmje.org/recommendations) from the International Committee of Medical Journal Editors (ICMJE).

For the policies on research and publication ethics not stated in the Instruction, the guidelines of the Committee of Publication Ethics (COPE; https://publicationethics.org/) or Good Publication Practice Guidelines for Medical Journals (https://kamje.or.kr/) should be applied.
Research ethics
Manuscripts with the following misconduct or dishonest acts cannot be published either online or in the journal.
• Forgery (fabrication): recording or reporting on made-up data or research results that do not exist.
• Alteration (falsification): manipulating research data, equipment, processes, or results intentionally to distort research contents or results.
• Plagiarism: using others’ ideas, research processes, contents, and/or results without proper authorization or citations.
Statement of human and animal rights and informed consent
Any investigations involving humans or animals should be approved by the Institutional Review Board (IRB) or the Animal Care Committee, respectively, of the institution(s) where the research was conducted. CE will not consider publishing any reports on studies involving humans or animals which have not received appropriate approval. Informed consent should be obtained from patients who participated in the clinical investigations, unless the relevant IRB waived this requirement. Human subjects' names, initials, hospitals, dates of birth, or other personal or identifying information should not be used. Images of human subjects should not be used unless the information is essential for scientific purposes, and explicit permission has been provided. Even when consent is provided, identifying details should be omitted if they are not essential. If identifying characteristics are altered to protect anonymity, authors should ensure that such alterations do not distort scientific meaning. If consent has not been obtained, it is generally insufficient to anonymize a photograph simply by using eye bars or blurring the face of the individual concerned. If the experiments involve animals, the research should be based on national or institutional guidelines for animal care and use. A statement describing whether the study was conducted with the approval of the IRB (with or without patient informed consent) or animal care committee must be provided in manuscripts describing human or animal research, respectively. CE may also request documentation of approval by the IRB or the Animal Care Committee for other types of articles when necessary. The content of each article is the responsibility of the authors and not of CE.
Originality and duplicate publication
Manuscripts that are under review or published by other journals will not be accepted for publication in CE. Any part of the accepted manuscript should not be duplicated in any other scientific journal without permission from the Editorial Board, although the figures and tables can be used freely if the original source is verified according to the Creative Commons Attribution Noncommercial License (https://creativecommons.org/licenses/by-nc/4.0/). It is mandatory for all authors to resolve any copyright issues when citing a figure or table from another journal that is not open access.
Authorship
All authors must have made a significant intellectual contribution to the manuscript according to the criteria formulated by the International Committee of Medical Journal Editors (ICMJE). Each author should have sufficiently participated in the work to take public responsibility for the content. Authorship credit should be based on (1) substantial contributions to conception and design, acquisition of data, 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 the work are appropriately investigated and resolved. All authors should meet criteria 1, 2, 3, and 4. All authors must state that they have approved the final submitted draft.
• Author contributions: Author contributions should be written according to "Contributor Roles in CRediT" format (https://casrai.org/credit/).
• Contributors: Any researcher who does not meet all four ICMJE criteria for authorship discussed above but contributes substantively to the study in terms of idea development, manuscript writing, conducting research, data analysis, and financial support should have their contributions listed in the Acknowledgments section of the article.
• Correction of authorship: Any changes to the author list after submission, such as a change in the order of the authors or the deletion or addition of authors, should only be made before the manuscript has been accepted and must be approved by the Editor. To request such a change, the Editor must receive the following from the corresponding author: (a) an explanation for the change to the author list and (b) written confirmation (e-mail, letter) from all authors that they agree with the addition, removal, or rearrangement. In the case of addition or removal of authors, this includes confirmation from the author being added or removed.
• Role of the 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 are met, such as providing details of authorship, ethics committee approval, clinical trial registration documentation, and gathering conflict of interest forms and statements. 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, additional information, or questions about the article.
Registration of clinical trial research
Any research involving a clinical trial should be registered with a primary national clinical trial registration site such as CRIS (https://cris.nih.go.kr/cris/index/index.do) or other primary national registry sites accredited by the World Health Organization (https://www.who.int/clinical-trials-registry-platform) or clinicaltrials.gov (http://clinicaltrials.gov/), a service of the United States National Institutes of Health.
Conflicts 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). The impact of these relationships can vary from being negligible to having a great potential for influencing reporting or 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, honoraria, and paid expert testimony) are the most easily identifiable conflicts of interest and are the most likely to undermine the credibility of the journal, authors, and science itself. However, conflicts can occur for other reasons, such as personal relationships, academic competition, and intellectual passion (http://www.icmje.org/conflicts-of-interest/). Authors must disclose any potential conflicts of interest in the manuscript. Conflicts of interest may occur during the research process; however, disclosure itself is an important point that can negate the conflict. Disclosure allows the editors, reviewers, and readers to approach the manuscript with an understanding of the situation in which the research work was performed.
Management of research and publication misconduct
When the journal faces suspected cases of research or publication misconduct, such as redundant (duplicate) publication, plagiarism, the use of fraudulent or fabricated data, changes in authorship, undisclosed conflicts of interest, ethical problems with a submitted manuscript, a reviewer who has appropriated an author’s idea or data, or complaints against editors, a resolution process will be undertaken. The resolution process will follow the flowchart provided by the Committee on Publication Ethics (COPE) (http://publicationethics.org/resources/flowcharts). Discussions and decisions regarding suspected cases of research or publication misconduct will be conducted by the Editorial Board.
Editorial responsibilities
The Editorial Board will continuously work to monitor and safeguard publication ethics through guidelines for retracting articles; the maintenance of the integrity of the academic record; ensuring that business needs do not compromise intellectual or ethical standards; publishing corrections, clarifications, retractions, and apologies when needed; and ensuring that there is no plagiarism or fraudulent data in publications. Editors have the following responsibilities: the responsibility and authority to reject/accept articles, to ensure the absence of conflicts of interest with respect to articles they reject/accept, the acceptance of a paper when reasonably certain, the publication of corrections or retractions when errors are found, and the preservation of the anonymity of reviewers.
2. Editorial policy
Copyright
The copyright of any paper published in this journal belongs to the Korean Society of Gastrointestinal Endoscopy. However, the legal responsibility remains with the authors. Public announcements of the content before publication are allowed only if required as a result of a public health emergency. All authors must sign the Transfer of Copyright Agreement when they submit their manuscript. The paper will not be published until the copyright transfer is complete.
Open access policy
CE is an open-access journal distributed under the terms of the Creative Commons Attribution Noncommercial License (https://creativecommons.org/licenses/by-nc/4.0/), which permits unrestricted noncommercial use, distribution, and reproduction in any medium, provided that the original work is properly cited. It is not necessary to request permission from the publisher to use the tables or figures of articles published in CE in other journals or books for scholarly and educational purposes.
Data sharing
CE encourages data sharing wherever possible unless ethical, privacy, or confidentiality concerns prevent this. Authors may deposit their data in a publicly accessible repository and include a link to the DOI within the text of the manuscript.
Archiving policy
CE provides electronic backup and preservation of access to the journal content from the 44th volume, 2011, in the event the journal is no longer archived in PubMed Central (https://www.ncbi.nlm.nih.gov/pmc/journals/1800/) or the National Library of Korea (https://www.nl.go.kr/). Authors can archive the publisher’s version/PDF of a previously published article.
Preprint policy
A preprint is a version of a scholarly paper preceding formal peer review and publication in a peer-reviewed scholarly journal. CE allows authors to submit preprints to the journal, without considering this to be a duplicate submission or publication. CE recommends that authors disclose the existence of a preprint with its DOI in a letter to the editor during the submission process. Otherwise, a plagiarism check program—Similarity Check (Crosscheck)—may flag the manuscript as containing excessive duplications. A preprint submission will be processed using the same peer-review process as a regular submission. If a preprint is accepted for publication, the authors should update the information on the preprint site with a link to the article published in CE, including the DOI for the CE article. It is strongly recommended that authors cite the article in CE instead of the preprint in their next submission to journals.
3. Manuscript submission and peer review
Manuscript submission
Any physician or researcher involved in clinical or basic research on gastrointestinal endoscopy can submit a manuscript for publication in CE. Please visit the manuscript management system (https://submit.e-ce.org/), as only online submissions will be considered for publication. Please consult the submission checklist (https://submit.e-ce.org/about/Checklist.php) prior to submission to ensure that all required elements have been included. The Copyright Transfer Agreement (https://submit.e-ce.org/about/Author.php) should be signed by all authors and submitted to the editorial office by fax or regular mail upon acceptance of the manuscript. The corresponding author should submit the manuscript.
Peer review
Every submitted manuscript will be peer-reviewed by at least two reviewers before a decision is made to accept, reject, or return it for revision. The review system is single-blinded, so the authors cannot identify the reviewers. The review process is conducted using a manuscript management system. If the authors are asked to revise the manuscript, they should revise it based on the reviewers’ comments or provide a reasonable answer to the reviewers’ comments, justifying why a suggested revision has not been made. The authors should reply and upload the revised manuscript within eight weeks after receiving the review results. Otherwise, the manuscript is considered to have been withdrawn. However, the authors can extend the revision period if more time is required.
Submission from editorial board members
All manuscripts from editors, employees, or members of the editorial board are processed in the same way as other unsolicited manuscripts. During the review process, editors, employees, or members of the editorial board will not engage in the selection of reviewers or the decision-making process for manuscripts on which they are authors. Editors will not handle their own manuscripts even if they are commissioned articles.
4. Publication types
Original articles
These describe new findings from clinical studies or basic research that may contribute to clinical diagnosis and treatment, or an understanding of pathogenesis or epidemiology.
Review articles
A concise compilation of the knowledge and skills in a specific area to provide hints for patient management or outline recent research activity. A review article is usually invited by the editorial board.
Systematic review and meta-analysis
These answer well-defined research questions by appraising the current literature. These should follow the PRISMA guidelines (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). In addition, CE recommends registration of the protocol of the systematic review and meta-analysis in the PROSPERO database (International Prospective Register of Systematic Reviews).
Editorials
Editorials express opinions on current topics of interest or provide comments on papers published elsewhere in the same issue. Editorials are usually solicited by the editor.
Case reports
A report on a single case or an analysis of a few cases to add to the clinical spectrum. The case should be clinically significant, new, and rare.
Image of issue
This format is to present state-of-the-art still images that will interest and help readers in the evaluation of unusual features of common conditions or in the diagnosis of unusual cases.
Video of issue
This format is to introduce state-of-the-art video that will interest and aid in the evaluation of unusual features of common conditions or in the diagnosis of unusual cases.
Brief reports
Reserved for the rapid and concise circulation of simple, but meaningful, data, remarkable preliminary findings before publication of a full report, or a follow-up study.
Letters to the editor
Any comments or opinions on published papers or suggestions for the journal are welcomed.
5. Manuscript preparation
The manuscript should be prepared using Microsoft Word. It should be formatted with double line spacing and 10-point font on A4-sized paper. The pages should be numbered consecutively, beginning from the title page.
Standard metric units
These units are used to describe length, height, weight, and volume. The unit of temperature is the degree Celsius (°C). All other units are expressed according to the International System of Units (SI). All units must be preceded by a single space, except for the percentage (%).
Reporting guidelines for specific study designs
Authors are encouraged to consult the reporting guidelines relevant to their specific research design. Good sources of reporting guidelines are the EQUATOR Network (https://www.equator-network.org/home/) and the United States National Institutes of Health/National Library of Medicine (https://www.nlm.nih.gov/services/research_report_guide.html).
CONSORT/STROBE/PRISMA: Randomized controlled trials must be presented according to the CONSORT guidelines (http://www.consort-statement.org). Observational studies must be conducted according to the STROBE guidelines (https://www.strobe-statement.org). Meta-analyses must be presented according to the PRISMA guidelines (http://www.prisma-statement.org/PRISMAStatement).
The checklist for the appropriate guidelines must be filled out and attached to the submission. Checklists are available as links in the Attach Files section of the submission process.
Cover letter
A cover letter should inform the editor that neither the submitted material nor portions of it have been published previously, or are under consideration for publication elsewhere. When more than one related manuscript has been published or is under consideration for publication in this or other journals, the authors must declare this in their letter and enclose copies of those publications for editorial perusal. Failure to do so may lead to automatic rejection of the submitted manuscript. The corresponding author certifies that all listed authors participated meaningfully in the study and that they have seen and approved the final manuscript.
The manuscript should be in the following order: Original articles: title page (including ethical statements, conflicts of interest, funding, acknowledgments, author contributions), abstract, main body (introduction, methods, results, discussion), references, figure legends, tables, and figures.
