Gastrointestinal Endoscopy publishes original, peer-reviewed articles on endoscopic procedures used in the study, diagnosis, and treatment of digestive diseases. Articles report on outcomes research, prospective studies, and controlled trials of new endoscopic instruments and treatment methods. Online features include full text of all articles, video and audio clips, and MEDLINE links to related articles. Category 1 CME credit can be earned by reading the text material and taking the CME examination online. Gastrointestinal Endoscopy has become the international forum for the newest developments in the specialty, bringing readers challenging reports from leading authorities throughout the world. The journal regularly publishes abstracts of important articles from other leading clinical publications, complete with commentaries from a panel of experts.
Aim: Gastrointestinal Endoscopy will be the preeminent advocate for the science and practice of endoscopy in the world. We will provide the highest quality endoscopic information at the point of care and at the cutting edge of science. We will continue to seek out and publish the best original articles, editorials and reviews as well as exciting new techniques, video cases and society guidelines.
Scope: Gastrointestinal Endoscopy is truly integrated into nearly all aspects of gastroenterology and hepatology as well as diseases and organs accessed via the GI tract. As such, we will review and publish articles not just studies directly involving endoscopy, but also conditions broadly relevant to the GIH community where endoscopy may play a role including inflammatory bowel disease, functional GI diseases and obesity.

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.
Table of Contents
- Prospective authors should refer to the Uniform Requirements for Manuscripts Submitted to Biomedical Journals1 (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. If your research involves interacting with living human subjects or with the data from living human subjects and if you intend to make the results of your research public (eg, publish an article in GIE), your research meets the definition of human subjects research and requires IRB review. This includes retrospective chart reviews.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
- GIE runs CrossCheck (iThenticate) on every article submitted.
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 email@example.com and explain the reasons.

New SubmissionsSubmission to this journal proceeds totally online, and you will be guided stepwise through the creation and uploading of your files. The system automatically converts your files to a single PDF file, which is used in the peer-review process. As part of the Your Paper Your Way service, you may choose to submit your manuscript as a single file to be used in the refereeing process. This can be a PDF file or a Word document, in any format or lay-out that can be used by referees to evaluate your manuscript. It should contain high enough quality figures for refereeing. If you prefer to do so, you may still provide all or some of the source files at the initial submission. Please note that individual figure files larger than 10 MB must be uploaded separately.
Please note: If your article is selected for revision or acceptance, you will, at that point, have to follow the usual journal requirements for submitting separate files in the appropriate formats.References
There are no strict requirements on reference formatting at submission. References can be in any style or format as long as the style is consistent. Where applicable, author(s) name(s), journal title/book title, chapter title/article title, year of publication, volume number/book chapter and the pagination must be present. Use of DOI, along with the preceding information, is highly encouraged. The reference style used by the journal will be applied to the accepted article by Elsevier at the proof stage. Note that missing data will be highlighted at proof stage for the author to correct.Formatting requirements
There are no strict formatting requirements, but all manuscripts must contain the essential elements needed to convey your manuscript, for example Abstract, Keywords, Introduction, Materials and Methods, Results, Conclusions, Artwork and Tables with Captions. If your article includes any Videos and/or other Supplementary material, this should be included in your initial submission for peer review purposes. Divide the article into clearly defined sections. Please do not format your manuscript in double column layout.Use of wordprocessing software
Regardless of the file format of the original submission, at revision you must provide us with an editable Word file of the entire article. Keep the layout of the text as simple as possible. Most formatting codes will be removed and replaced on processing the article. The electronic text should be prepared in a way very similar to that of conventional manuscripts (see also the Guide to Publishing with Elsevier: https://www.elsevier.com/guidepublication). See also the section on Electronic artwork. To avoid unnecessary errors you are strongly advised to use the 'spell-check' and 'grammar-check' functions of your wordprocessor.Figure captions
Ensure that each illustration has a caption. A caption should comprise a description of the illustration (not on the figure itself). Keep text in the illustrations themselves to a minimum but explain all symbols and abbreviations used.JOURNAL PUBLISHING AGREEMENT
- At the time an article is accepted and sent to Elsevier for production, a Journal Publishing Agreement will be e-mailed to the corresponding author. This original document, containing the author(s) ink signatures, should be returned to Elsevier at the following address. This must be on file before publication can occur.

Examples of financial conflicts include employment, consultancies, stock ownership, honoraria, paid expert testimony, patent applications, and research and travel grants within 3 years of beginning the work submitted. If there are no conflicts of interest, authors must state that there are none. These disclosures will appear with the article in print and online. Authors must use the GIE disclosure form, available as a link in the Attach Files part of the submission process.
Associate Editors and Reviewers will recuse themselves from involvement in processing manuscripts when they identify a conflict of interest.For a complete explanation of what does and does not constitute a conflict of interest, please see Gastrointest Endosc 2006;63(7):33A-35A or view the document online at www.giejournal.org or www.asge.org.
TitleThe title should be descriptive, but not overly long. Do not include brand names or acronyms in the title. If the article describes an animal study, indicate that in the title.
AbstractFor Original Articles and New Methods and Materials, a structured abstract of no more than 250 words should use all of the following headings:
- Background and Aims
Do not include brand names in the abstract; re-write the abstract to include generic terms only. Submissions to Reviews 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.
Randomized controlled trials must be presented according to the CONSORT guidelines (http://www.consort-statement.org).5 Observational studies must be presented according to the STROBE guidelines (http://www.strobe-statement.org ). Meta-analyses must be presented according to the PRISMA guidelines (http://prisma-statement.org/statement.htm). The checklist for the appropriate guideline must be filled out and attached to your Original Article or New Methods 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.
Each author must have made a contribution toward the production of the article, as recommended at http://www.icmje.org, authorship criteria.Author Contributions
Each author must have made a contribution toward the production of the article, as recommended at http://www.icmje.org, authorship criteria.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 seehttp://www.techexpo.com/techdata/techcntr.html. After laboratory values, normal values should be presented in parentheses in the text. A separate Word file listing all abbreviations and acronyms will need to be uploaded during the submission process.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.6Statistics
- 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 TablesFigures (including color photographs) are published without charge to authors.
- Instructions for creating figures can be found below and at http://www.editorialmanager.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 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 (eg, 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 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.
- Random figures will be checked for image manipulation.
- 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, please email the GIE Editorial Office at email@example.com for special uploading instructions. 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.
- Each video file must be less than 100 MB in size. If the file is larger than 100 MB, you will need to break it up into two or more smaller files.
- 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 (http://www.giejournal.org).
- 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 (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 (http://www.ncbi.nlm.nih.gov/nlmcatalog/journals).
- The list of references, in numeric sequence, should be typed at the end of the article. In the submitted version of the manuscript, references should not appear as footnotes or endnotes, and if you have used a program such as EndNote or Reference Manager to create them, the links between the reference numbers and the citations must be removed using the following steps: (1) Using the "Select All" feature (Ctrl-A for PCs. Cmd-A for Macs), highlight the entire text of the file, including the references. (2) Use the keystroke command Ctrl-6 for PCs or Cmd-6 for Macs. (3) Save. This will remove the links (permanently) without disturbing the reference numbers or the citations. It is recommended that you save one copy of your manuscript with the EndNote links in place (for your reference) and one copy of your manuscript without the EndNote links (for submission purposes).
- If excerpts from other copyrighted works are included, the author(s) must obtain written permission from the copyright owners and credit the source(s) in the article. These permissions must be submitted to the Editorial Office before publication can occur.
- Preprinted forms for use by authors in these cases can be obtained from Elsevier's Rights Department, Philadelphia, PA, USA: phone (+1) 215-239-3804, fax (+1) 215-239-3805.
- Requests may also be completed online via the Elsevier homepage (https://www.elsevier.com/authors/obtaining-permission-to-re-use-elsevier-material).
The journal encourages authors to supplement in-article microscopic images with corresponding high resolution versions for use with the Virtual Microscope viewer. The Virtual Microscope is a web based viewer that enables users to view microscopic images at the highest level of detail and provides features such as zoom and pan. This feature for the first time gives authors the opportunity to share true high resolution microscopic images with their readers. More information and examples are available at https://www.elsevier.com/about/content-innovation/virtual-microscope. Authors of this journal will receive an invitation e-mail to create microscope images for use with the Virtual Microscope when their manuscript is first reviewed. If you opt to use the feature, please contact firstname.lastname@example.org for instructions on how to prepare and upload the required high resolution images.ARTICLES IN PRESS
