Instructions for Authors

Journal of Clinical Gastroenterology is a peer-reviewed journal directed to an audience of clinical practitioners. The Journal publishes original articles, review articles, research reports, case reports, letters, meeting reports, and announcements pertinent to its mission. The goal of the Journal is to publish material in all areas of gastroenterology, hepatology and nutrition that will assist the practitioner in making clinical decisions.

Ethical/Legal Considerations
A submitted manuscript must be an original contribution not previously published (except as an abstract or a preliminary report), must not be under consideration for publication elsewhere, and, if accepted, must not be published elsewhere in similar form, in any language, without the consent of Lippincott Williams & Wilkins. Each person listed as an author is expected to have participated in the study to a significant extent. Although the editors and referees make every effort to ensure the validity of published manuscripts, the final responsibility rests with the authors, not with the Journal, its editors, or the publisher.

A conflict of interest disclosure and funding declaration must be included on the title page of the manuscript and in Editorial Manager. Authors with nothing to declare should provide a statement to that effect. Manuscripts submitted without the required disclosures will be returned to the authors.

Declaration of Funding Source: ACKNOWLEDGMENT OF GRANTS OR FINANCIAL SUPPORT MUST BE DECLARED. Authors of all articles in which the effect of a drug, appliance, or treatment is evaluated must also acknowledge all support from the manufacturer of such drug, appliance, or treatment or its competitor. Authors of review articles, editorials, letters to the editor, and other commentaries must disclose any financial interests that might have an impact on the views expressed in the article, editorial, letter, or commentary. The Declaration of Funding Source statement will be included in the published article or commentary.

Patient anonymity and informed consent: It is the author's responsibility to ensure that a patient's anonymity be carefully protected and to verify that any experimental investigation with human subjects reported in the manuscript was performed with informed consent and following all the guidelines for experimental investigation with human subjects required by the institution(s) with which all the authors are affiliated. Authors should mask patients' eyes and remove patients' names from figures unless they obtain written consent from the patients and submit written consent with the manuscript.

Copyright: All authors must sign a copy of the Journal's "Authorship Responsibility, Financial Disclosure, and Copyright Transfer.” A copy of the form is made available to the submitting author within the Editorial Manager submission process. Co-authors will automatically receive an Email with instructions on completing the form upon submission.

Conflicts of Interest
Authors must state all possible conflicts of interest in the manuscript, including financial, consultant, institutional and other relationships that might lead to bias or a conflict of interest. If there is no conflict of interest, this should also be explicitly stated as none declared.  All sources of funding should be acknowledged in the manuscript. All relevant conflicts of interest and sources of funding should be included on the title page of the manuscript with the heading “Conflicts of Interest and Source of Funding:”. For example:

Conflicts of Interest and Source of Funding: A has received honoraria from Company Z. B is currently receiving a grant (#12345) from Organization Y,  and is on the speaker’s bureau for Organization X – the CME organizers for Company A. For the remaining authors none were declared.

Each author must complete and submit the journal’s copyright transfer agreement, which includes a section on the disclosure of potential conflicts of interest based on the recommendations of the International Committee of Medical Journal Editors, “Uniform Requirements for Manuscripts Submitted to Biomedical Journals” (

A copy of the form is made available to the submitting author within the Editorial Manager submission process. Co-authors will automatically receive an Email with instructions on completing the form upon submission.


Open access
Authors of accepted peer-reviewed articles have the choice to pay a fee to allow perpetual unrestricted online access to their published article to readers globally, immediately upon publication. Authors may take advantage of the open access option at the point of acceptance to ensure that this choice has no influence on the peer review and acceptance process. These articles are subject to the journal's standard peer-review process and will be accepted or rejected based on their own merit.

The article processing charge (APC) is charged on acceptance of the article and should be paid within 30 days by the author, funding agency or institution. Payment must be processed for the article to be published open access. For a list of journals and pricing please visit our Wolters Kluwer Open Health Journals page.

A) Creating Digital Artwork

1. Learn about the publication requirements for Digital Artwork:  

2. Create, Scan and Save your artwork  and compare your final figure to the Digital Artwork Guideline Checklist (below).

3. Upload each figure to Editorial Manager in conjunction with your manuscript text and tables.


B)  Digital Artwork Guideline Checklist

Here are the basics to have in place before submitting your digital artwork:

  Artwork  should be saved as TIFF, EPS, or MS Office (DOC, PPT, XLS) files. High resolution PDF files are also acceptable.

  Crop out any white or black space surrounding the image.

  Diagrams, drawings, graphs, and other line art must be vector or saved at a resolution of at least 1200 dpi. If created in an MS Office program, send the native (DOC, PPT, XLS)  file.

  Photographs, radiographs and other halftone images must be saved at a resolution of at least 300 dpi.

  Photographs and radiographs with text must be saved as postscript or at a resolution of at least 600 dpi.

  Each figure must be saved and submitted as a separate file. Figures should not be embedded in the manuscript text file.



  Cite figures consecutively in your manuscript.

   Number figures in the figure legend in the order in which they are discussed.

   Upload figures consecutively to the Editorial Manager web site and enter figure numbers consecutively in the Description field when uploading the files. 

Figure legends: Include legends for all figures. They should be brief and specific, and they should appear on a separate manuscript page after the references. Use scale markers in the image for electron micrographs, and indicate the type of stain used.

Color figures: The journal accepts for publication color figures that will enhance an article. Authors who submit color figures will receive an estimate of the cost for color reproduction. If they decide not to pay for color reproduction, they can request that the figures be converted to black and white at no charge.

Tables: Create tables using the table creating and editing feature of your word processing software (e.g., Word, WordPerfect). Cite tables consecutively in the text, and number them in that order. Each table should appear on a separate page and should include the table title, appropriate column heads, and explanatory legends (including definitions of any abbreviations used). Do not embed tables within the body of the manuscript. They should be self-explanatory and should supplement, rather than duplicate, the material in the text.

Case Reports:
Due to the large number of manuscripts we receive and limited publication space, we will only accept case reports that report or confirm a totally new observation or drug interaction.

Supplemental Digital Content

Supplemental Digital Content (SDC): Authors may submit SDC via Editorial Manager to LWW journals that enhance their article's text to be considered for online posting. SDC may include standard media such as text documents, graphs, audio, video, etc. On the Attach Files page of the submission process, please select Supplemental Audio, Video, or Data for your uploaded file as the Submission Item. If an article with SDC is accepted, our production staff will create a URL with the SDC file. The URL will be placed in the call-out within the article. SDC files are not copy-edited by LWW staff, they will be presented digitally as submitted. For a list of all available file types and detailed instructions, please visit

SDC Call-outs:
Supplemental Digital Content must be cited consecutively in the text of the submitted manuscript. Citations should include the type of material submitted (Audio, Figure, Table, etc.), be clearly labeled as "Supplemental Digital Content," include the sequential list number, and provide a description of the supplemental content. All descriptive text should be included in the call-out as it will not appear elsewhere in the article.
We performed many tests on the degrees of flexibility in the elbow (see Video, Supplemental Digital Content 1, which demonstrates elbow flexibility) and found our results inconclusive.

List of Supplemental Digital Content:
A listing of Supplemental Digital Content must be submitted at the end of the manuscript file. Include the SDC number and file type of the Supplemental Digital Content. This text will be removed by our production staff and not be published.
Supplemental Digital Content 1. wmv

SDC File Requirements:
All acceptable file types are permissible up to 10 MBs. For audio or video files greater than 10 MBs, authors should first query the journal office for approval. For a list of all available file types and detailed instructions, please visit

Style: Pattern manuscript style after the American Medical Association Manual of Style (9th edition). Stedman's Medical Dictionary (27th edition) and Merriam Webster's Collegiate Dictionary (10th edition) should be used as standard references. Refer to drugs and therapeutic agents by their accepted generic or chemical names, and do not abbreviate them. Use code numbers only when a generic name is not yet available. In that case, supply the chemical name and a figure giving the chemical structure of the drug is required. Copyright or trade names of drugs should be capitalized and placed in parentheses after the name of the drug. Names and locations (city and state in USA; city and country outside USA) of manufacturers of drugs, supplies, or equipment cited in a manuscript are required to comply with trademark law and should be provided in parentheses. Units of measure should be expressed in the metric system, and temperatures should be expressed in degrees Celsius. Conventional units should be written as SI units as appropriate.

Page Proofs and Corrections

Corresponding authors will receive electronic page proofs to check the copyedited and typeset article before publication.
