About the Journal of Digestive Disorders and Diagnosis

A peer-reviewed, open-access journal dedicated to advancing diagnosis, treatment, and research in gastrointestinal and hepatobiliary diseases through rapid dissemination of high-quality clinical and translational science.

JDDD's mission is to serve as a trusted, comprehensive, and freely accessible resource for the latest findings and advancements in digestive health. We publish multidisciplinary content that informs evidence-based practice, drives mechanistic discovery, and shapes patient-centered care strategies. Our commitment extends beyond publication—we actively support authors through transparent editorial workflows, ethical stewardship, and global visibility initiatives.

We champion research excellence by:

• Ensuring scientific integrity: Rigorous peer review by subject matter experts in gastroenterology, hepatology, pancreatic diseases, inflammatory bowel disease, gastrointestinal oncology, and advanced endoscopy.
• Accelerating knowledge dissemination: Rapid editorial decisions (average 12 days to first decision) and immediate online publication upon acceptance.
• Maximizing research impact: Open access licensing (Creative Commons CC BY 4.0) enables unrestricted sharing, citation, and reuse by clinicians, educators, and guideline developers worldwide.
• Supporting diverse methodologies: Original research, systematic reviews, meta-analyses, case series, technical innovations, editorials, and hypothesis-generating reports.
• Promoting ethical transparency: Mandatory conflict of interest disclosure, institutional review board approval documentation, and adherence to COPE guidelines for publication ethics.

JDDD publishes research across the entire spectrum of digestive disorders, reflecting the anatomical and functional complexity of the gastrointestinal system. Our scope encompasses clinical investigations, translational research, diagnostic innovations, therapeutic trials, and epidemiological studies addressing diseases of the digestive tract and accessory organs.

All published articles are immediately and permanently available online without subscription fees or paywalls. This unrestricted access maximizes your research's visibility, citation potential, and real-world impact—enabling clinicians in resource-limited settings, medical students, policymakers, and patient advocacy groups to benefit from your findings.

JDDD recognizes that timely dissemination is critical in rapidly evolving fields like inflammatory bowel disease biologics, endoscopic innovation, and hepatocellular carcinoma management. Our streamlined editorial workflow delivers first decisions within approximately 12 days and publishes accepted manuscripts online within 2 days of final acceptance. Authors receive regular status updates and can track their submissions through our manuscript management system.

Every submission undergoes evaluation by independent experts with specialized knowledge in the relevant subdiscipline. Reviewers assess study design, statistical methodology, clinical relevance, reproducibility, ethical compliance, and contribution to existing literature. Constructive feedback strengthens manuscripts regardless of final decision, and authors are given fair opportunity to address reviewer concerns through revision.

JDDD maintains reasonable Article Processing Charges (APCs) designed to reflect global economic diversity. Fees can be covered by authors, funding agencies, or institutional memberships. We offer APC waivers or discounts for corresponding authors from low- and middle-income countries, early-career researchers, and unfunded studies demonstrating significant clinical or scientific merit. Contact our editorial office to discuss eligibility.

JDDD values the scholarly contributions of peer reviewers and editorial board members. Reviewers and editors who provide thorough, timely reports receive recognition through certificates of service and APC discounts on future submissions. This acknowledgment supports professional development, tenure portfolios, and continuing medical education requirements.

JDDD provides multiple submission pathways to accommodate diverse author preferences and institutional workflows. Before submission, authors should carefully review our Instructions for Authors, which detail formatting requirements, ethical guidelines, authorship criteria, conflict of interest policies, and required documentation.

Upon acceptance and peer review completion, articles are published under a Creative Commons Attribution 4.0 International (CC BY 4.0) license.
