Scope

Manuscript Scope and Types

The journal publishes original research, clinical trials, reviews, and translational studies in intestinal research.

Article types include original research, clinical trials, systematic reviews, meta analyses, cohort studies, brief reports, and methodological innovations. Case based learning is considered when clinical insights are substantial.

Submissions should demonstrate gastrointestinal relevance, clear methodology, and appropriate statistical reporting.

Preparation

Before You Submit

Confirm scope fit, authorship order, and ethical approvals before submission.

  • Verify reporting guideline alignment for the study design
  • Prepare ethics approvals and consent statements
  • Confirm data availability and funding disclosures
  • Review references and include DOIs when available

A concise cover letter should summarize novelty, clinical relevance, and study design. Provide preprint disclosures when applicable.

Authorship

Authorship and Contributions

Authorship should reflect substantial contributions and shared accountability for the work.

  • Confirm that all authors approve the submitted version
  • Describe author contributions using a consistent role description
  • Identify the corresponding author for editorial communication
  • Disclose funding sources and sponsor roles

Gift authorship and honorary attribution are not acceptable. Contributors who do not meet authorship criteria should be acknowledged in a separate section.

Cover Letter

Cover Letter and Suggested Reviewers

A focused cover letter improves editorial screening and reviewer matching.

  • Summarize the main clinical contribution in two or three sentences
  • Explain how the study advances gastrointestinal practice
  • List key outcomes and any trial registration details
  • Suggest reviewers with relevant expertise and no conflicts

Provide institutional email addresses for suggested reviewers and note any conflicts to avoid assignment delays.

Structure

Manuscript Structure

Use a standard structure to support reviewer assessment and clinical translation.

  • Title page with author affiliations and corresponding author contact
  • Structured abstract with objectives, methods, results, and conclusions
  • Keywords aligned with gastrointestinal outcomes
  • Main text with Introduction, Methods, Results, Discussion
  • Funding, conflicts, and author contributions
  • References with complete citation details

Abstracts should include key numerical results and clear conclusions aligned with the data.

Title Page

Title Page and Correspondence

A complete title page enables accurate indexing and efficient communication.

  • Full author names with institutional affiliations
  • Corresponding author email and mailing address
  • Running title that reflects the main outcome
  • Word count for the main text

Include ORCID identifiers where available to improve attribution and indexing accuracy.

Formatting

Formatting and Style

Consistent formatting improves reviewer feedback and indexing accuracy.

  • Define abbreviations at first use
  • Include units for all measurements
  • Keep tables and figures close to their first citation
  • Use consistent terminology for outcomes and interventions

Ensure that numbers in the abstract match the main text, tables, and figures to avoid review delays.

Files

File Formats and Naming

Consistent file formats support efficient production and accurate archiving.

  • Submit the manuscript in an editable format
  • Provide figures as separate high resolution files
  • Name files clearly with figure or table numbers
  • Check that supplementary files are labeled and referenced

Clear file naming reduces production questions and speeds proof preparation.

Abstract

Abstract Guidance

Structured abstracts should summarize objectives, methods, outcomes, and clinical significance.

  • Include key numerical results and confidence intervals
  • State the study population and setting
  • Report the primary endpoint clearly
  • Avoid undefined abbreviations

A strong abstract improves discoverability and supports accurate indexing in gastrointestinal databases.

Imaging

Imaging and Figure Requirements

Provide high resolution images and clear captions with modality details.

  • Include scale bars or acquisition details for imaging
  • Describe imaging protocols and device models
  • Ensure image adjustments are applied uniformly
  • Provide raw data if requested for verification

For endoscopy, intestinal MRI, ultrasound, or CT imaging, report acquisition parameters and post processing methods.

Figures

Tables and Figures

Clear visuals improve reviewer interpretation and reader comprehension.

  • Number tables and figures consecutively
  • Provide detailed captions that stand alone
  • Report units and statistical markers consistently
  • Ensure legends match data in the main text

Avoid embedding tables as images to support accessibility and accurate indexing.

Methods

Methods and Statistical Reporting

Transparent methods improve reproducibility and clinical interpretation.

  • Describe study setting, recruitment, and sample size rationale
  • Define primary and secondary outcomes before analysis
  • Report effect sizes, confidence intervals, and missing data handling
  • State statistical software and version details

Describe subgroup analyses with justification and avoid over interpretation of exploratory findings.

References

References and Citations

Accurate citations support reviewer assessment and improve cross platform linking.

  • Use recent and relevant gastrointestinal literature
  • Include DOIs where available
  • Verify author names, journal titles, and publication years
  • Cite data sources and clinical guidelines appropriately

Reference accuracy improves citation tracking and supports readers who want to verify findings.

Acknowledgments

Acknowledgments and Funding

Disclose support and contributions that do not meet authorship criteria.

List funding sources, grant numbers, and sponsor roles. Acknowledge technical support or data collection assistance in a dedicated section.

Transparent funding disclosure strengthens trust and supports compliance reporting.

Ethics

Ethics and Compliance

All studies involving humans require ethics approval and informed consent.

  • Ethics approval identifiers and oversight body
  • Informed consent statements and privacy protections
  • Clinical trial registration for interventional studies
  • Conflict of interest and funding disclosures

Animal studies should follow recognized welfare guidelines and include protocol approval identifiers.

Registration

Clinical Trial Registration

Interventional studies should be registered in a recognized trial registry before enrollment.

  • Provide registry name and identifier in the manuscript
  • Explain protocol deviations with justification
  • Include primary endpoint details from the registry
  • Report recruitment dates and study status

Registration promotes transparency and helps readers evaluate study integrity.

Privacy

Patient Privacy and Images

Patient privacy must be protected in text, figures, and supplementary material.

  • Remove identifiers from imaging and clinical photographs
  • Confirm consent for any identifiable images
  • Describe privacy protections for datasets
  • Limit sensitive details in case descriptions

If patient consent is required, include a clear statement in the manuscript.

Data

Data Availability and Sharing

Include a data availability statement with repository details or access conditions.

  • Public repositories such as Zenodo, Figshare, or Dryad
  • Institutional repositories with persistent identifiers
  • Controlled access repositories for sensitive clinical data
  • Supplementary files with supporting tables

Provide data dictionaries and readme files for complex datasets and analysis pipelines.

Supplement

Supplementary Materials

Supplementary materials support transparency and reproducibility.

  • Additional tables, figures, or extended methods
  • Appendices for protocols or survey instruments
  • Code scripts or analysis workflows
  • Data dictionaries and variable descriptions

Label supplementary files clearly and reference them within the main text.

Guidelines

Reporting Guidelines

Use reporting frameworks appropriate to study design.

  • CONSORT for randomized trials
  • PRISMA for systematic reviews
  • STROBE for observational studies
  • CARE for case reports

Include trial registration identifiers and describe protocol deviations when applicable.

Preprints

Preprints and Prior Publication

Preprint posting should be disclosed at submission and referenced in the cover letter.

Provide the preprint link and version date so reviewers can assess changes and avoid duplication.

Prior publication of substantial portions of the work should be declared to avoid redundancy.
