GASTROINTESTINAL ENDOSCOPY publishes original papers reporting investigations and observations relating to endoscopic procedures used in the study and treatment of digestive diseases. All submissions undergo peer review. Submissions may be accompanied by supplemental materials posted to the electronic version of the journal; such materials also will be subject to peer review. Careful adherence to submission guidelines will avoid unnecessary delays, as incomplete submissions may be returned to the authors before initiation of the peer review process.

ETHICAL CONCERNS

  • Prospective authors should refer to the Uniform Requirements for Manuscripts Submitted to Biomedical Journals1 (External link http://www.icmje.org ) to familiarize themselves with ethical conventions of publication; specifically, the issues of redundant or duplicate publication, authorship criteria, and potential conflicts of interest.
  • The Editor reserves the right to investigate alleged improprieties related to these conventions.
  • When questions of scientific misconduct or dishonesty in research occur, the Editor reserves the right to proceed according to the guidelines of the Office of Research Integrity.2 Authors may be asked to provide the appropriate documentation of compliance, as well as the data on which the manuscript is based.
  • Investigations involving human subjects or animals must have prior approval of the appropriate institutional review board or an equivalent body.3,4
  • In countries where institutional review is not established practice, a statement must be included in the methods section that the research was carried out in accordance with the Helsinki Declaration.3

REGISTRATION OF HUMAN CLINICAL TRIALS

Gastrointestinal Endoscopy follows the International Committee of Medical Journal Editors (ICMJE)'s Uniform Requirements for Manuscripts Submitted to Biomedical Journals. All prospective human clinical trials eventually submitted in GIE must have been registered through one of the registries approved by the ICMJE, and proof of that registration must be submitted to GIE along with the article. For further details and explanation of which trials need to be registered as well as a list of ICMJE-acceptable registries, please go to External link http://www.icmje.org .

SPECIAL SUBJECT REPOSITORIES

Certain repositories such as PubMed Central ("PMC") are authorized under special arrangement with Elsevier to process and post certain articles such as those funded by the National Institutes of Health under its Public Access policy (see elsevier.com for more detail on our policy).

Articles accepted for publication in an Elsevier journal from authors who have indicated that the underlying research reported in their articles was supported by an NIH grant will be sent by Elsevier to PMC for public access posting 12 months after final publication. The version of the article provided by Elsevier will include peer-review comments incorporated by the author into the article. Because the NIH 'Public Access' policy is voluntary, authors may elect not to deposit such articles in PMC. If you wish to 'opt out' and not deposit to PMC, you may indicate this by sending an e-mail to NIHauthorrequest@elsevier.com.

There will be no need for you to post your manuscript directly to PubMed Central, and any such posting is prohibited. Individual modifications to this general policy may apply to some Elsevier journals and to its society publishing partners.

  • Background
  • Objective
  • Design
  • Setting
  • Patients
  • Interventions

  • Conclusions

Do not include brand names in the abstract; re-write the abstract to include generic terms only. Submissions to Reviews, Brief Reports, Case Series, and At the Focal Point do not require an abstract.

Text Structure

Manuscripts should be structured according to the following:
  • Title: What is the main conclusion of the study?
  • Introduction: Why carry out the study?
  • Background: What is already known on the issue?
  • Methods: How was the study done?
  • Results: What were the main findings?
  • Discussion: What do these results add to the current body of knowledge?
  • The paper's emphasis should be on tables, figures, and/or images. Authors should stress why the results are important and what the study adds to current knowledge.

CONSORT/STROBE

Randomized controlled trials must be presented according to the CONSORT guidelines (External link http://www.consort-statement.org ).5 Observational studies must be presented according to the STROBE guidelines (External link http://www.strobe-statement.org ). The checklist for the appropriate guideline must be filled out and attached to your Original Article submission. Checklists are available as links in the Attach Files part of the submission process.

The paper's emphasis should be on tables, figures, and/or images. Authors should stress why the results are important and what the study adds to current knowledge.

Take-home Message

If you are submitting an Original Article or New Methods article, write 1 to 3 sentences interpreting (not summarizing) your work and placing it into context. What is the significance and what is the most important concept from your study for readers? What are the implications?

Author Contributions

Each submission must include an uploaded file outlining the contribution(s) that each author made toward the production of the article.

Product and Drug Names

Generic drug names should be used; trade names may be inserted in parentheses after the initial mention of the drug. Product names should be treated similarly, listing the manufacturer's name, city, and state in parentheses. Do not put product or drug names in the title or the abstract of the article.

Laboratory Values

Laboratory values should be presented in SI units. For conversion from non-SI units see External link http://www.techexpo.com/techdata/techcntr.html. After laboratory values, normal values should be presented in parentheses in the text.

Abbreviations and Acronyms

Spell out abbreviations and acronyms the first time the terms appear in the text. You may follow the list of standard abbreviations found in the AMA Manual of Style, 10th edition.6

Statistics

  • All studies reporting levels of significance must include the sample size calculation and power used in that calculation. Justification for deviating from calculated sample sizes must be addressed.
  • Statistical techniques that do not appear in the published literature should be presented as an appendix. All but the most standard tests should be referenced.
  • For reporting means, standard deviations, and standard error, the following format should be used: "mean (SD)" and "mean ± SE." For reporting medians, the values of the interquartile range (IQR) and those of the range should be given.
  • Report levels of significance for all comparisons made, whether significant or not, with P-values or confidence intervals.
  • Papers that overstate the level of significance of findings due to multiple comparisons must be adjusted statistically and the results and discussion presented only with respect to the corrected findings. The problem may be avoided through the use of multivariate methods; however, significance levels may be corrected with post-hoc tests, such as Bonferroni's method. Multiple comparisons of data from a single data set typically can occur in either of the two following situations: repeated measurements of a single variable are tested over time, or several correlated variables are used in different tests of hypotheses.
  • Interpretation of results of regression analyses requires that units of continuous variables as well as categories of discrete or ordinal variables be specified. Additionally, for logistic regression and Cox regression analyses, the baseline or reference category of discrete or ordinal variables must also be given.

Figures and Tables

Figures (including color photographs) are published without charge to authors.
  • Instructions for creating figures can be found below and at External link http://ees.elsevier.com/gie/ .
  • It is crucial that you create your figures at the correct resolution before uploading them to the EES website. For step-by-step instructions (with screenshots of common graphics applications for PC or Mac users) on how to create your figures at the proper resolution, see "Application guidelines" at External link http://authors.elsevier.com . For best results, please follow these guidelines carefully.
  • Figure images should be provided in EPS or TIF format. Graphics software such as Photoshop and Illustrator (not presentation software such as PowerPoint, CorelDraw, or Harvard Graphics) should be used to create the figures.
  • Illustrations should be saved at the highest resolution setting and sized as close to a column width (3 to 4 inches) as possible.
  • Upload each part of each figure separately in EES. Do not label figures with numbers or letters; the compositor will use a standardized font. Do be sure to name the figure file with the correct figure number and letter (e.g., Figure 1A). Do not make the figure legend part of the figure tiff file; figure legends must be placed at the end of the Word text file.
  • Use the colors from our "Figure Color Scheme," located at External link http://www.giejournal.org/content/figure_color_scheme, to add color to your figure charts and graphs (not tables).
  • Legends should be typed at the end of the text document and include enough information so that figures can be interpreted without reference to the text. Give staining and magnification for photomicrographs of histologic slides.
  • Tables should be Word documents and should be placed at the end of the text Word document. All tables and figures must be cited in the text in consecutive order. Do not add color to tables; standardized color is added by the compositor.
  • At the discretion of the Editor, images and tables may appear in the print version of the Journal, the electronic version, or both.

Video/Computer Graphics

  • Videos and computer graphics (ie, slide presentations with or without animation) can be submitted through EES. If the file is too large to upload into EES, it can be sent on original, edited CD-ROMs or DVD-Rs in Windows-compatible format to the GIE Editorial Office. Three copies of the disk containing the video/computer graphics should be submitted by mail or courier when the manuscript is submitted. Be sure to include the manuscript title and date of submission so that the disks can be cross-referenced to the manuscript submission. Please indicate the video component on the submission cover page.
  • All videos or graphics submitted must be of the highest quality possible.
  • Submissions of videos that were originally recorded through the S-video or RGB outputs of the endoscope processor are desired.
  • Gastrointestinal Endoscopy may edit any video or computer graphics. Reviewers, following the usual policy with illustrations, may suggest changes in the video or computer graphic.
  • A sound track is highly recommended, but not required.
  • Maximum cumulative length of videos or computer graphics is 8 minutes, and materials may be divided into several smaller clips not to exceed 8 minutes in total. If the video or animation is divided into several clips, each clip should be identified at the beginning of the section (eg, Video Clip 1, Graphic 1) and on the disk. Several videos/graphics may be on the same disk, but if they are separate clips, they must be saved as separate files. When needed, use of simple transitions, eg, fade in/out dissolve, dip to color dissolve, are suggested.
  • Concise legends (typed on a separate page) must accompany each video clip or computer graphic presentation.
  • The following formats for video will be accepted: MPEG-1 or MPEG-2 (.mpg), Quicktime (.mov), or Compuserve GIF (.gif). Please contact the publisher about the use of other formats.
  • A graphic will be used in the text to indicate the location of a video clip or computer graphic component. Videos/computer graphics for accepted manuscripts will not be returned, nor will they be accepted separately from a rejected manuscript.
  • If the article is accepted for publication, the video will be digitized and permanently archived on the Gastrointestinal Endoscopy website (External link http://www.giejournal.org ).

References

  • References must be cited in the text in consecutive order and identified by superscript numbers.
  • It is the author's responsibility to check the accuracy of all references by verifying them against the original documents. Citations can be verified by using PubMed's Citation Matcher ( External link http://www.ncbi.nlm.nih.gov/entrez/query/static/citmatch.html ).
  • Examples of correct forms of reference, in accordance with Uniform Requirements for Manuscripts Submitted to Biomedical Journals,1 are given in the online submission instructions.
  • Follow Index Medicus for journal title abbreviations (External link http://www.ncbi.nlm.nih.gov/nlmcatalog/journals ).
