AIMS AND SCOPE
Digestive Endoscopy is the official journal of the Japan Gastroenterological Endoscopy Society and the Asian Pacific Society for Digestive Endoscopy. Digestive Endoscopy serves as a medium for presenting original articles that offer significant contributions to knowledge in the broad field of endoscopy.
The Journal also includes Reviews, New Instruments and Techniques, Clinical Trial Notes, Case Reports, Endoscopic Images of Interest, How I do it, Editorials, Letters to the Editor, abstracts and news items that may be of interest to endoscopists.

EDITORIAL REVIEW AND ACCEPTANCE
The acceptance criteria for all papers are the quality and originality of the research and its significance to our readership. Except where otherwise stated, manuscripts are peer reviewed by two anonymous reviewers and the Editor. The Editorial Board reserves the right to refuse any material for publication and advises that authors should retain copies of submitted manuscripts and correspondence as material cannot be returned. Final acceptance or rejection rests with the Editorial Board.
Manuscripts should be written so that they are intelligible to the professional reader who is not a specialist in the particular field. Where contributions are judged as acceptable for publication on the basis of scientific content, the Editor or the Publisher reserves the right to modify typescripts to eliminate ambiguity and repetition and improve communication between author and reader. If extensive alterations are required, the manuscript will be returned to the author for revision.

SUBMISSION OF MANUSCRIPTS
Manuscripts can be submitted online at http://mc.manuscriptcentral.com/den. Authors must supply an email address as all correspondence will be by email. Two files should be supplied: the covering letter and the manuscript (in Word or rich text format (.rtf)). The covering letter should be uploaded as a file not for review.
All articles submitted to be the Journal must comply with these instructions. Failure to do so will result in return of the manuscript and possible delay in publication. For assistance, please contact the Editorial Office of Digestive Endoscopy (email: digestive_endoscopy@jges.or.jp; phone: +81 3 3291 4111; fax: +81 3 3291 5568).
Authors please note that Word 2007 is not yet compatible with journal production systems. Unfortunately, the journal cannot accept Microsoft Word 2007 documents until such time as a stable producion version is released. Please use Word's 'Save As' option therefore to save your document as an older (.doc) file type.
• Submissions should be double-spaced.
• All margins should be at least 30 mm.

• Do not use Enter at the end of lines within a paragraph.
• Turn the hyphenation option off; include only those hyphens that are essential to the meaning.
• Specify any special characters used to represent non-keyboard characters.
• Take care not to use I (ell) for 1 (one), O (capital o) for 0 (zero) or ß (German esszett) for β (Greek beta).
• Use a tab, not spaces, to separate data points in tables. If you use a table editor function, ensure that each data point is contained within a unique cell (i.e. do not use carriage returns within cells).
Each figure should be supplied as a separate file, with the figure number incorporated in the file name. For submission, low-resolution figures saved as .jpg or .bmp files should be uploaded, for ease of transmission during the review process. Upon acceptance of the article, high-resolution figures (at least 300 d.p.i.) saved as .eps or .tif files should be uploaded. Digital images supplied only as low-resolution files cannot be used. Further instructions are available at the submission site (http://mc.manuscriptcentral.com/den).

Covering letter
Papers are accepted for publication in the journal on the understanding that the content has not been published or submitted for publication elsewhere. This must be stated in the covering letter.
The covering letter must contain an acknowledgment that all authors have contributed significantly, and that all authors are in agreement with the content of the manuscript.
In keeping with the latest guidelines of the International Committee of Medical Journal Editors, each author's contribution to the paper is to be quantified.
Authors should declare any financial support or relationships that may pose conflict of interest.
If tables or figures have been reproduced from another source, a letter from the copyright holder (usually the Publisher stating authorization to reproduce the material, must be attached to the covering letter.

Author material archive policy
Authors who require the return of any submitted material that is accepted for publication should inform the Editorial Office after acceptance. If no indication is given that author material should be returned, Blackwell Publishing will dispose of all hardcopy and electronic material two months after publication.

ETHICAL CONSIDERATIONS
Authors must state that the protocol for the research project has been approved by a suitably constituted Ethics Committee of the institution within which the work was undertaken and that it conforms to the provisions of the Declaration of Helsinki in 1995 (as revised in Tokyo 2004), available at http://www.wma.net/e/policy/b3.htm. Digestive Endoscopy retains the right to reject any manuscript on the basis of unethical conduct of either human or animal studies.
All investigations on human subjects must include a statement that the subject gave informed consent and patient anonymity should be preserved.
In general, submission of a case report should be accompanied by the written consent of the subject (or parent/guardian) before publication; this is particularly important where photographs are to be used or in cases where the unique nature of the incident reported makes it possible for the patient to be identified. While the Editorial Board recognizes that it might not always be possible or appropriate to seek such consent, the onus will be on the authors to demonstrate that this exception applies in their case.
Any experiments involving animals must be demonstrated to be ethically acceptable and where relevant conform to national guidelines for animal usage in research.

COPYRIGHT
Authors publishing in the Journal will be asked to sign an Exclusive Licence Form. In signing the form it is assumed that authors have obtained permission to use any copyrighted or previously published material. All authors must read and agree to the conditions outlined in the form, and must sign the form or agree that the corresponding author can sign on their behalf. Articles cannot be published until a signed form has been received. Authors can download the form from http://www.blackwellpublishing.com/pdf/den_elf.pdf

STYLE OF THE MANUSCRIPT
Manuscripts should follow the style of the Vancouver agreement detailed in the International Committee of Medical Journal Editors' revised 'Uniform Requirements for Manuscripts Submitted to Biomedical Journals: Writing and Editing for Biomedical Publication,' as presented at http: //www.ICMJE.org/.
Spelling. The Journal uses US spelling and authors should therefore follow the latest edition of the Merriam-Webster's Collegiate Dictionary.
Abbreviations. Standard abbreviations may be used and should be defined in the abstract and on first mention in the text. In general, however, abbreviations should be used sparingly and only where they ease the reader's task by reducing repetition of long, technical terms. Initially use the word in full, followed by the abbreviation in parentheses. Thereafter use the abbreviation.
Units. SI units (metre (m), kilogram (kg) etc.) must be used wherever possible. Statistics and measurements should always be given in numerals; that is, 10 mm. Confusing mathematical notation, and particularly subscripts and superscripts, should be avoided.
Trade names. Chemical substances should be referred to by the generic name only. Trade names should not used. Drugs should be referred to by their generic names. If proprietary drugs have been used in the study, refer to these by their generic name, mentioning the proprietary name, and the name and location of the manufacturer, in parentheses.

PARTS OF THE MANUSCRIPT
Manuscripts should be presented in the following order: (i) title page, (ii) abstract and key words, (iii) text, (iv) acknowledgments, (v) references, (vi) appendices, (vii) figure legends, (viii) tables (each table complete with title and footnotes) and (ix) figures. Footnotes to the text are not allowed and any such material should be incorporated into the text as parenthetical matter.
Title page
The title page should contain (i) the title of the paper, (ii) the full names of the authors and (iii) the addresses of the institutions at which the work was carried out together with (iv) the name, full postal and email address, plus facsimile and telephone numbers, of the author to whom correspondence about the manuscript, proofs and requests for offprints should be sent. The present address of any author, if different from that where the work was carried out, should be supplied in a footnote.
The title should be short, informative and contain the major key words. A short running title (less than 40 characters, including spaces) should also be provided.
Abstract and key words
A structured abstract of 250 words or fewer (using no abbreviations, footnotes, trade names or references) is required for Original Articles and New Instruments and Techniques. Abstracts should be structured in four paragraphs using the following subtitles: Aim, Methods, Results and Conclusion. Non-structured abstracts of less than 200 words are required for Case Reports, Endoscopic Images of Interest, How I do it, and Reviews. The abstract should not contain references.
Up to five key words (for the purposes of indexing) should be supplied below the abstract, in alphabetical order, and should be taken from those recommended by the US National Library of Medicine's Medical Subject Headings (MeSH) browser list (www.nlm.nih.gov/mesh/meshhome.html).

Appendices
These should be placed at the end of the paper, numbered in Roman numerals and referred to in the text. If written by a person other than the author of the main text, the writer's name should be included below the title.
Tables
Tables should be self-contained and complement, but not duplicate, information contained in the text. Tables should be numbered consecutively in Arabic numerals. Each table should be typed on a separate page with a comprehensive but concise legend above the table. Vertical lines should not be used to separate columns. Column headings should be brief, with units of measurement in parentheses; all abbreviations should be defined in footnotes. Footnote symbols: †, ‡, §, , should be used (in that order) and *, **, *** should be reserved for P-values. Statistical measures such as SD or SEM should be identified in the headings. The table and its legend/footnotes should be understandable without reference to the text.
Figures
All illustrations (line drawings and photographs) are classified as figures. Figures should be cited in consecutive order in the text. Figures should be sized to fit within the column (88 mm), intermediate (120 mm) or the full text width (180 mm). Magnifications should be indicated using a scale bar on the illustration. Line figures should be sharp, black and white graphs or diagrams, drawn professionally or with a computer graphics package. Lettering must be included and should be sized to be no larger than the journal text. Magnifications should be indicated using a scale bar on the illustration.
Color figures
Colour figure files should be set up as CMYK (cyan, magenta, yellow, black) and not as RGB (red, green, blue) so that colours as they appear on screen will be a closer representation of how they will print in the Journal.
Supporting information (video)
Supporting Information is provided by the authors to support the content of an article but they are not integral to that article. They are hosted online together with the articles but do not appear in the print version of the article. Supporting Information must be submitted together with the article for peer review. They can be in the form of tables, figures, appendices, audio and video. Reference to Supporting Information in the main body of the article is allowed. However, it should be noted that excessive reference to a piece of Supporting Information may indicate that it would be better suited as a proper reference or fully included figure/table. The materials are published as they are supplied and are not checked or typeset in any way. All Supporting Information files should come with a legend, listed at the end of the main article. Each figure and table file should not be larger than 5MB, although video files may be larger.
Video formats accepted: MPEG, QuickTime, and AVI. MPEG if the preferred format. Videos should be maximum 5 minutes long. If your video is longer, it must be split into a series of multiple videos and submitted as Video 1, 2, 3 etc. Each video must be accompanied by a legend in the main text of the manuscript under the Supporting Information header that explains readers what happens in each Supporting Information video. The legends must state what type of file is used, e.g. MPEG, QuickTime or AVI.
Figure legends
Legends should be self-explanatory and typed on a separate page. The legend should incorporate definitions of any symbols used and all abbreviations and units of measurement should be explained so that the figure and its legend is understandable without reference to the text. (Provide a letter stating copyright authorization if figures have been reproduced from another source.)
