    Aims & scope

    Gastrointestinal (GI) endoscopy is developing rapidly: Modern endoscopic imaging offers a plethora of detailed visual information and endoscopic procedures are becoming increasingly sophisticated and complex. Therefore endoscopists need a new appropriate tool for visual transmission of proceedings in endoscopy. The innovative Video Journal and Encyclopedia of GI Endoscopy takes these developments into account and aims to be the premium and first choice international reference for endoscopic findings and procedures. The focus on high-quality video demonstrations of endoscopic findings and procedures offers a completely new way of presenting the work of GI experts and allows for easy comprehension of information. Additional concise manuscripts to each video detail the procedures and the findings in a bullet point style. All articles are peer-reviewed and available both online and on mobile devices. The unique format of the Video Journal and Encyclopedia of GI Endoscopy provides two elements:
    An EXPERT VIDEO ENCYCLOPEDIA as a reference tool with systematic step-by-step demonstrations of common and rare GI pathologies and up-to-date endoscopic procedures. The video sequences in this section are of high educational impact and allow endoscopists and other health care providers to recognize a wide array of pathological findings, review existing techniques, and acquire new endoscopic techniques for implementation in their own clinical work.
    A SCIENTIFIC VIDEO JOURNAL and premium reference for findings and techniques, demonstrating cutting edge endoscopic techniques and scientific results as well as clinical cases. In the journal section of VJGIEN original research will be published reporting latest results in respect to endoscopic procedures used in the treatment of gastrointestinal diseases.

Authors should include a statement in the manuscript that informed consent was obtained for experimentation with human subjects. The privacy rights of human subjects must always be observed.

    Conflict of interest

    All authors must disclose any financial and personal relationships with other people or organizations that could inappropriately influence (bias) their work. Examples of potential conflicts of interest include employment, consultancies, stock ownership, honoraria, paid expert testimony, patent applications/registrations, and grants or other funding. See also http://www.elsevier.com/conflictsofinterest. Further information and an example of a Conflict of Interest form can be found at: http://help.elsevier.com/app/answers/detail/a_id/286/p/7923.

    VJGIEN requires full disclosure of all potential conflicts of interest. All sources of funding supporting the work are to be declared. At the end of the manuscript text, under a subheading "Conflict of Interest", all authors must disclose any financial and personal relationships with other people or organizations that could inappropriately influence (bias) their work. If there are no conflicts of interest, the authors should state, "The authors declare that there are no conflicts of interest."

    Submission declaration

    Submission of an article implies that the work described has not been published previously (except in the form of an abstract or as part of a published lecture or academic thesis or as an electronic preprint, see http://www.elsevier.com/postingpolicy), that it is not under consideration for publication elsewhere, that its publication is approved by all authors and tacitly or explicitly by the responsible authorities where the work was carried out, and that, if accepted, it will not be published elsewhere including electronically in the same form, in English or in any other language, without the written consent of the copyright-holder.

    Authorship

    All authors should have made substantial contributions to all of the following: (1) the conception and design of the study, or 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 submitted.

    Changes to authorship

    This policy concerns the addition, deletion, or rearrangement of author names in the authorship of accepted manuscripts:
    Before the accepted manuscript is published in an online issue: Requests to add or remove an author, or to rearrange the author names, must be sent to the Journal Manager from the corresponding author of the accepted manuscript and must include: (a) the reason the name should be added or removed, or the author names rearranged and (b) written confirmation (e-mail, fax, 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. Requests that are not sent by the corresponding author will be forwarded by the Journal Manager to the corresponding author, who must follow the procedure as described above. Note that: (1) Journal Managers will inform the Journal Editors of any such requests and (2) publication of the accepted manuscript in an online issue is suspended until authorship has been agreed.
    After the accepted manuscript is published in an online issue: Any requests to add, delete, or rearrange author names in an article published in an online issue will follow the same policies as noted above and result in a corrigendum.

    Reporting clinical trials

    Randomized controlled trials should be presented according to the CONSORT guidelines. At manuscript submission, authors must provide the CONSORT checklist accompanied by a flow diagram that illustrates the progress of patients through the trial, including recruitment, enrollment, randomization, withdrawal and completion, and a detailed description of the randomization procedure. The CONSORT checklist and template flow diagram can be found on http://www.consort-statement.org.

    Registration of clinical trials

    Registration in a public trials registry is a condition for publication of clinical trials in this journal in accordance with International Committee of Medical Journal Editors (ICMJE, http://www.icmje.org) recommendations. Trials must register at or before the onset of patient enrolment. The clinical trial registration number should be included at the end of the abstract of the article. A clinical trial is defined as any research study that prospectively assigns human participants or groups of humans to one or more health-related interventions to evaluate the effects of health outcomes. Health-related interventions include any intervention used to modify a biomedical or health-related outcome (for example drugs, surgical procedures, devices, behavioural treatments, dietary interventions, and process-of-care changes). Health outcomes include any biomedical or health-related measures obtained in patients or participants, including pharmacokinetic measures and adverse events. Purely observational studies (those in which the assignment of the medical intervention is not at the discretion of the investigator) will not require registration.

    Submit your article
    Please submit your article via http://ees.elsevier.com/vjgien.

    Referees

    Please submit the names and institutional e-mail addresses of several potential referees. For more details, visit our Support site. Note that the editor retains the sole right to decide whether or not the suggested reviewers are used.



    Your submission consists of up to five items:

    • 1. Video file (mandatory)
      If your video file is bigger than 500 MB please contact the Editorial Coordinator: VJGIEN@elsevier.com
    • 2. Accompanying manuscript (mandatory)
      The structure of your manuscript depends on the section you would like to submit it to. For details and template please see "Choose the Article Type".
    • 3. Journal Publishing License Agreement (mandatory)
      Please carefully select the Creative Commons Attribution License (see paragraph "Open Access") you wish to apply to your article and submit the respective agreement form along with your article
    If you require professional voiceover and/or editing of text slides (integration of text slides into your video at the positions defined in the voiceover script template), please also submit the following items. Please note that these services will be charged extra.
    • 4. Text slides (PPT file)
      Use of the template (see "Choose the Article Type") is mandatory. Please submit if you require professional editing.
    • 5. Voiceover script (excel file)
      Use and submission of the voiceover script template is mandatory if you require professional voiceover. (We recommend to also use the template when creating your own voiceover and for correct positioning of text slides in your video.)

    Preparing the video

    • Your video should have the appropriate length to address the topic in question adequately, but should not extend approx. 10 minutes.
    • Please be sure that your video file shows all relevant aspects.
    • Please do not insert an introductory slide (title, author names and affiliations) - this will be done in a consistent manner by our multimedia team.
    • Your video should include text slides (see "Preparing the text slides") to highlight the most important aspects of your findings and may also include explanatory figures. Please ensure to use only core information. The use of the template is mandatory.
    • We strongly encourage you to use histology and/or radiology images in your video for teaching purposes.
    • Please deliver a voiced-over video: While conducting the procedure, narrate throughout in present tense, as if you were teaching a colleague to do the procedure. Including your own 'tips and tricks' along with the basic steps of the procedure will help to enhance the video. It is important for any live narration or discussion to be captured with minimal background noise. It is recommended that a lavaliere/lapel microphone be used on the individual(s) speaking for best quality and clarity. Professional voiceover can be arranged at additional cost (please contact the Editorial Coordinator).
    • Optional for the section "Supplementation to the Encyclopedia": If you wish, please send us your picture (.jpg or .tif format) for publication on our website.

    Digital file formats

    • Formats accepted: MPG (.mpg), MP4 (.mp4), Apple Quick Time (.mov), Microsoft Audio/Video Interlaced format (.avi)
    • Upper limit for the size of files is 500 MB
    • If you have any questions please contact the Editorial Coordinator: VJGIEN@elsevier.com

    Preparing the text slides

    The text slides should highlight the most important aspects of your video. Please use the template set of slides (see "Choose the Article Type"). The position of each slide within the video is indicated in the voiceover script template.

    1. Conflict of Interest/CC License
      Please enter the title of your video, state any conflicts of interest (please also state if there are no conflicts) and choose the appropriate CC license based on your Journal Publishing License Agreement.
    2. Background
      Please briefly describe the background of your publication in bullet points
    3. Take Home Message/Impact on Clinical Practice
      This slide will conclude your video. Please enter in bullet points.
    You may also insert additional slides at other positions if appropriate. Please use our flexible slide template for this purpose.

    If you intend to submit a voiced-over video, please insert the text slides at the positions defined in the voiceover script template (esp. if narration is required while the slides are shown). Please pay special attention to correct spelling and grammar as well as uniform layout of your slides. Any corrections to the text slides will significantly delay publication of your video!
    Alternatively, the slides can be edited into your video by our Multimedia Team. In this case, submission of the separate text slide file is mandatory. Please note that this service will be charged extra.

    Please make sure to use Arial or Arial narrow no smaller than 24 pt in order to allow for all information to be legible also on mobile devices with a small screen (smartphone).

    Preparing the voiceover

    If you intend to request professional voiceover, please use the mandatory script template (see "Choose the Article Type") and fill it out according to the instructions. We recommend use of the template even if you are going to submit an already voiced video. The template will help you prepare the voice stream according to our requirements.

    If possible, please provide an already voiced-over video. If necessary, professional voiceover can be arranged at additional cost. Please contact the Editorial Coordinator for more information.

    The voiceover should be an expert explanation of the procedure, including tips and tricks and imitating a tutorial situation, thus providing a 'take-home-message'. It can also include an explanation on equipment and materials. Please ensure that the text is in present tense. The language should be vivid as if the user was attending a live process ("Now you can see …", "This is …").

    IMPORTANT: Please ensure the length of the voice over fits well with the length of your video. The maximum average word count per 10 seconds is 15.

    To prepare a voiceover script you will need to watch the video in a format that allows you to make note of the start and end time for each piece of narration. Time intervals should be short (no more than 30 seconds) to ensure exact matching of the spoken text and the images, and long pauses should be avoided. Voiceover is welcome for text slides (please do not simply read the slides but summarize in your own words). Please provide start and end time in the following format: hr:min:sec, e.g. 00:00:00.

    It is mandatory that you "time" the audio narration to match the length of the video where possible - reading the written script aloud while you watch the selected clip is one way to do this. The voiceover script template will alert you if your word count exceeds the maximum average word count of 15 words in 10 seconds.

    Please specify how long your video file is (time) and which size it has (data). You can give this information in the voiceover script.
    Ensure that the information on the slides can easily be read and understood within the given time.

    Preparing the manuscript

    It is important that the text files be saved in the native format of the wordprocessor used. The text should be in single-column format. Keep the layout of the text as simple as possible. Most formatting codes will be removed and replaced on processing the article. In particular, do not use the wordprocessor's options to justify text or to hyphenate words. However, do use bold face, italics, subscripts, superscripts etc. When preparing tables, if you are using a table grid, use only one grid for each individual table and not a grid for each row. If no grid is used, use tabs, not spaces, to align columns. The electronic text should be prepared in a way very similar to that of conventional manuscripts (see also the Guide to Publishing with Elsevier: http://www.elsevier.com/guidepublication). To avoid unnecessary errors you are strongly advised to use the 'spell-check' and 'grammar-check' functions of your wordprocessor.

    Style
    The manuscript is considered to accompany the video. It is therefore necessary to keep the manuscript short. With the exception of the manuscript parts Abstract and Discussion (see manuscript template), please use bullet-point style. A bullet point is considered a statement of up to 3 sentences referring to a precise question.

    The manuscript template can be used for all article types, however, each article type has different requirements. Each paragraph heading will detail (in brackets) which article types it applies to. If no information is given, the paragraph is mandatory for all types.

    After choosing an article type, please read the manuscript template carefully and delete all paragraphs that do not apply before you start writing. All instructions and examples are written in grey font and should be deleted before submission.

    Details on article structure
    You will find more detailed information on the individual parts of each article type in the manuscript template (see " Choose the Article Type").

    Essential title page information

    Title. Concise and informative. Titles are often used in information-retrieval systems. Avoid abbreviations and formulae where possible.
    Author names and affiliations. Where the family name may be ambiguous (e.g., a double name), please indicate this clearly. Present the authors' affiliation addresses (where the actual work was done) below the names. Indicate all affiliations with a lower-case superscript letter immediately after the author's name and in front of the appropriate address. Provide the full postal address of each affiliation, including the country name and, if available, the e-mail address of each author.
    Corresponding author. Clearly indicate who will handle correspondence at all stages of refereeing and publication, also post-publication. Ensure that phone numbers (with country and area code) are provided in addition to the e-mail address and the complete postal address. Contact details must be kept up to date by the corresponding author.
    Present/permanent address. If an author has moved since the work described in the article was done, or was visiting at the time, a 'Present address' (or 'Permanent address') may be indicated as a footnote to that author's name. The address at which the author actually did the work must be retained as the main, affiliation address. Superscript Arabic numerals are used for such footnotes.

    Structured abstract

    A structured abstract, by means of appropriate headings, should provide the context or background for the research and should state its purpose, basic procedures (selection of study subjects or laboratory animals, observational and analytical methods), main findings (giving specific effect sizes and their statistical significance, if possible), and principal conclusions. It should emphasize new and important aspects of the study or observations.

    Keywords

    Immediately after the abstract, provide a maximum of 6 keywords, using American spelling and avoiding general and plural terms and multiple concepts (avoid, for example, 'and', 'of'). Be sparing with abbreviations: only abbreviations firmly established in the field may be eligible. These keywords will be used for indexing purposes.

    Abbreviations

    Define abbreviations that are not standard in this field in a footnote to be placed on the first page of the article. Such abbreviations that are unavoidable in the abstract must be defined at their first mention there, as well as in the footnote. Ensure consistency of abbreviations throughout the article.

    Units

    Follow internationally accepted rules and conventions: use the international system of units (SI). If other units are mentioned, please give their equivalent in SI.

    Artwork

    Image manipulation
    Whilst it is accepted that authors sometimes need to manipulate images for clarity, manipulation for purposes of deception or fraud will be seen as scientific ethical abuse and will be dealt with accordingly. For graphical images, this journal is applying the following policy: no specific feature within an image may be enhanced, obscured, moved, removed, or introduced. Adjustments of brightness, contrast, or color balance are acceptable if and as long as they do not obscure or eliminate any information present in the original. Nonlinear adjustments (e.g. changes to gamma settings) must be disclosed in the figure legend.

    Electronic artwork
    General points
    • Make sure you use uniform lettering and sizing of your original artwork.
    • Embed the used fonts if the application provides that option.
    • Aim to use the following fonts in your illustrations: Arial, Courier, Times New Roman, Symbol, or use fonts that look similar.
    • Number the illustrations according to their sequence in the text.
    • Use a logical naming convention for your artwork files.
    • Provide captions to illustrations separately.
    • Size the illustrations close to the desired dimensions of the printed version.
    • Submit each illustration as a separate file.
    A detailed guide on electronic artwork is available on our website:
    http://www.elsevier.com/artworkinstructions
    You are urged to visit this site; some excerpts from the detailed information are given here.
    Formats
    If your electronic artwork is created in a Microsoft Office application (Word, PowerPoint, Excel) then please supply 'as is' in the native document format.
    Regardless of the application used other than Microsoft Office, when your electronic artwork is finalized, please 'Save as' or convert the images to one of the following formats (note the resolution requirements for line drawings, halftones, and line/halftone combinations given below):
    EPS (or PDF): Vector drawings, embed all used fonts.
    TIFF (or JPEG): Color or grayscale photographs (halftones), keep to a minimum of 300 dpi.
    TIFF (or JPEG): Bitmapped (pure black & white pixels) line drawings, keep to a minimum of 1000 dpi.
    TIFF (or JPEG): Combinations bitmapped line/half-tone (color or grayscale), keep to a minimum of 500 dpi.
    Please do not:
    • Supply files that are optimized for screen use (e.g., GIF, BMP, PICT, WPG); these typically have a low number of pixels and limited set of colors;
    • Supply files that are too low in resolution;
    • Submit graphics that are disproportionately large for the content.

    Illustration services

    Elsevier's WebShop (http://webshop.elsevier.com/illustrationservices) offers Illustration Services to authors preparing to submit a manuscript but concerned about the quality of the images accompanying their article. Elsevier's expert illustrators can produce scientific, technical and medical-style images, as well as a full range of charts, tables and graphs. Image 'polishing' is also available, where our illustrators take your image(s) and improve them to a professional standard. Please visit the website to find out more.

    Figure captions
    Ensure that each illustration has a caption. Supply captions separately, not attached to the figure. A caption should comprise a brief title (not on the figure itself) and a description of the illustration. Keep text in the illustrations themselves to a minimum but explain all symbols and abbreviations used.

    Tables

    Number tables consecutively in accordance with their appearance in the text. Place footnotes to tables below the table body and indicate them with superscript lowercase letters. Avoid vertical rules. Be sparing in the use of tables and ensure that the data presented in tables do not duplicate results described elsewhere in the article.

    References

    Citation in text
    Please ensure that every reference cited in the text is also present in the reference list (and vice versa). Any references cited in the abstract must be given in full. Unpublished results and personal communications are not recommended in the reference list, but may be mentioned in the text. If these references are included in the reference list they should follow the standard reference style of the journal and should include a substitution of the publication date with either 'Unpublished results' or 'Personal communication'. Citation of a reference as 'in press' implies that the item has been accepted for publication.

    Reference links
    Increased discoverability of research and high quality peer review are ensured by online links to the sources cited. In order to allow us to create links to abstracting and indexing services, such as Scopus, CrossRef and PubMed, please ensure that data provided in the references are correct. Please note that incorrect surnames, journal/book titles, publication year and pagination may prevent link creation. When copying references, please be careful as they may already contain errors. Use of the DOI is encouraged.

    Web references
    As a minimum, the full URL should be given and the date when the reference was last accessed. Any further information, if known (DOI, author names, dates, reference to a source publication, etc.), should also be given. Web references can be listed separately (e.g., after the reference list) under a different heading if desired, or can be included in the reference list.

    Reference style
    Text: Indicate references by number(s) in square brackets in line with the text. The actual authors can be referred to, but the reference number(s) must always be given.
    List: Number the references (numbers in square brackets) in the list in the order in which they appear in the text.

    Submission checklist

    The following list will be useful during the final checking of an article prior to sending it to the journal for review. Please consult this Guide for Authors for further details on any item.

    Ensure that you have:

    • chosen one of the available article types and used the mandatory templates for your submission
    • made up your mind if you prefer to insert the text slides yourself and create your own voiceover (no extra costs), or if you will request professional voiceover and/or editing upon submission (extra cost, longer production time)
    • selected a CC license that defines how others may use your open access video and article once published (Journal Publishing License Agreement), and included the license information both in your manuscript and the appropriate text slide in your video
    • closely followed the instructions while preparing manuscript, text slides and voiceover

    Ensure that the following items are present:

    One author has been designated as the corresponding author with contact details:

    • E-mail address
    • Full postal address
    • Phone numbers
    All necessary files have been uploaded:
    • Video
    • Manuscript
    • Journal Publishing License Agreement
    (optional:)
    • Voiceover script
    • Text slides

    Further considerations:

    • Manuscript and text slides have been 'spell-checked' and 'grammar-checked'
    • All author names and affiliations have been entered correctly both in the manuscript and in EES
    • Any additional text slides have been prepared using the flexible slide template
    • References are in the correct format for this journal
    • All references mentioned in the Reference list are cited in the text, and vice versa
    • Permission has been obtained for use of copyrighted material from other sources (including the Web)
    • Conflict of Interest Statement has been included on the manuscript and on the appropriate text slide in the video
    • All ethical standards have been considered and included in the manuscript

    Use of the Digital Object Identifier

    The Digital Object Identifier (DOI) may be used to cite and link to electronic documents. The DOI consists of a unique alpha-numeric character string which is assigned to a document by the publisher upon the initial electronic publication. The assigned DOI never changes. Therefore, it is an ideal medium for citing a document, particularly 'Articles in press' because they have not yet received their full bibliographic information. Example of a correctly given DOI (in URL format; here an article in the journal Physics Letters B):
    http://dx.doi.org/10.1016/j.physletb.2010.09.059
    When you use a DOI to create links to documents on the web, the DOIs are guaranteed never to change.

    Proofs

    During production, proofs of the edited video and the typeset manuscript will be emailed to the corresponding author separately. In order to ensure fast production, please respond within 7 days.

    One set of page proofs (as PDF files) will be sent by e-mail to the corresponding author (if we do not have an e-mail address then paper proofs will be sent by post) or, a link will be provided in the e-mail so that authors can download the files themselves. Elsevier now provides authors with PDF proofs which can be annotated; for this you will need to download Adobe Reader version 7 (or higher) available free from http://get.adobe.com/reader. Instructions on how to annotate PDF files will accompany the proofs (also given online). The exact system requirements are given at the Adobe site: http://www.adobe.com/products/reader/tech-specs.html.
    If you do not wish to use the PDF annotations function, you may list the corrections (including replies to the Query Form) and return them to Elsevier in an e-mail. Please list your corrections quoting line number. If, for any reason, this is not possible, then mark the corrections and any other comments (including replies to the Query Form) on a printout of your proof and return by fax, or scan the pages and e-mail, or by post. Please use this proof only for checking the typesetting, editing, completeness and correctness of the text, tables and figures. Significant changes to the article as accepted for publication will only be considered at this stage with permission from the Editor. We will do everything possible to get your article published quickly and accurately – please let us have all your corrections within 7 days. It is important to ensure that all corrections are sent back to us in one communication: please check carefully before replying, as inclusion of any subsequent corrections cannot be guaranteed. Proofreading is solely your responsibility. Note that Elsevier may proceed with the publication of your article if no response is received.

    Offprints

    The corresponding author, at no cost, will be provided with a personalized link providing 50 days free access to the final published version of the article on ScienceDirect. This link can also be used for sharing via email and social networks. For an extra charge, paper offprints can be ordered via the offprint order form which is sent once the article is accepted for publication. Both corresponding and co-authors may order offprints at any time via Elsevier's WebShop (http://webshop.elsevier.com/myarticleservices/offprints). Authors requiring printed copies of multiple articles may use Elsevier WebShop's 'Create Your Own Book' service to collate multiple articles within a single cover (http://webshop.elsevier.com/myarticleservices/booklets).
