Endoscopy Submission Guide: Scope, Format & Tips (2026)

Published by Thieme, Endoscopy targets practicing endoscopists and researchers focused on procedural advances. It works best for manuscripts that would change how an endoscopist thinks about diagnosis, intervention, safety, or technique selection.

The editorial board prioritizes papers that change practice. They want studies that make endoscopists do something differently next Monday. This means they favor comparative effectiveness research, technical refinements, and diagnostic advances over descriptive studies.

• Article types accepted:
• Original articles (most common, 3,000-4,000 words)
• Case reports (1,500 words maximum)
• Technical notes (1,000 words maximum)
• Reviews (invitation only)
• Letters to the editor (500 words maximum)

Original articles dominate their publication mix. Case reports need to demonstrate genuine novelty, not just interesting presentations. Technical notes work well for procedural modifications or equipment evaluations.

The journal particularly values multicenter studies, randomized controlled trials, and systematic reviews with meta-analysis. Single-center retrospective studies face higher bars unless they report substantial patient numbers or novel techniques.

Geographic distribution matters. Papers from established endoscopy centers in Europe, North America, and Asia receive preference, though this isn't explicit policy. The editorial board includes representatives from major academic centers worldwide, and they tend to favor work from institutions they recognize.

Publication timing runs about 4-6 months from acceptance to online publication, with print following 2-3 months later. They don't offer fast-track publication for most submissions.

Word limits vary by article type and the journal enforces them strictly. Original articles allow 4,000 words excluding references and figure legends. Case reports limit to 1,500 words. Technical notes cap at 1,000 words.

• Structured abstract requirements:

Original articles need structured abstracts with Background, Methods, Results, and Conclusions sections. Each section gets 2-3 sentences maximum. Don't exceed 250 words total.

Case reports use unstructured abstracts limited to 150 words. Technical notes also use unstructured format with 100-word limit.

• Reference formatting:

Use Vancouver style with numbered citations in order of appearance. The journal allows up to 40 references for original articles, 20 for case reports, and 15 for technical notes.

Format journal references as: Author AA, Author BB. Title of article. Journal Name Year;Volume:Page numbers.

Book references need: Author AA. Title of Book. Edition number. City: Publisher; Year. Page numbers.

• Figure specifications:

Submit figures at publication quality initially. The journal won't ask for revisions of low-resolution images. Use TIFF or EPS format at minimum 300 DPI resolution. Color figures reproduce well, but ensure your images remain interpretable in grayscale.

Label figures as Figure 1, Figure 2, etc. Use panels (A, B, C) for multiple images within one figure. Include scale bars for histological or endoscopic images.

• Table formatting:

Keep tables simple with clear headers and minimal formatting. Avoid vertical lines and excessive borders. Each table needs a descriptive title and numbered sequentially.

Tables should stand alone without requiring the main text for interpretation. Define all abbreviations in table footnotes using superscript letters (a, b, c).

• Common formatting failures:
• References not in Vancouver style
• Figures embedded at low resolution
• Tables with complex formatting that doesn't convert properly
• Missing institutional review board statements
• Incomplete author disclosure forms

Your cover letter determines whether editors send your paper for review or desk reject it immediately. Endoscopy editors spend 2-3 minutes maximum reading cover letters, so make your key points obvious.

• First paragraph structure:

State your article type, main finding, and clinical relevance in 2-3 sentences. Example: "We submit this original research article reporting a randomized controlled trial comparing cold snare polypectomy to hot snare polypectomy for polyps 4-9mm in diameter. Our study of 324 patients demonstrates non-inferiority of cold snare technique with significantly reduced perforation risk."

• Second paragraph - why Endoscopy:

Explain specifically why this journal fits your work. Don't use generic statements about "high-quality journal" or "international readership." Instead: "This study directly addresses the technical question raised in Dr. Smith's recent Endoscopy editorial about optimal polypectomy techniques for intermediate-sized lesions."

• Third paragraph - significance:

Describe how your findings change endoscopic practice. Editors want to know what endoscopists will do differently after reading your paper. Quantify the impact when possible: "These results suggest 15% of colonoscopy complications could be prevented by adopting cold snare technique."

• Avoid these cover letter mistakes:
• Summarizing your entire study (that's what abstracts do)
• Listing author qualifications unless directly relevant
• Claiming "first study" without proper literature review
• Using promotional language about "novel" or "first-ever" findings
• Failing to mention endoscopic relevance specifically

Keep cover letters to one page. Longer letters suggest you can't identify your key message clearly. For detailed cover letter examples across different article types, see our journal cover letter template guide.

Endoscopy aims for first decisions within 8-12 weeks of submission, though complex studies may take longer. The process breaks down into predictable phases.

• Week 1-2: Editorial screening

Editors check scope fit, formatting compliance, and basic quality markers. About 30-40% of submissions get desk rejected during this phase for scope mismatch or obvious methodological problems.

• Week 3-4: Reviewer assignment

For papers advancing to peer review, editors contact potential reviewers. Finding reviewers for highly specialized endoscopic techniques can extend this phase.

• Week 5-12: Peer review

Most papers receive 2-3 reviewer reports. Endoscopy uses single-blind review (reviewers know author identities, authors don't know reviewers). Reviewers typically get 3-4 weeks for initial reviews.

• Status meanings in Editorial Manager:
• "Under review" means reviewers have accepted assignments
• "Reviews completed" indicates all reports submitted, editor making decision
• "Decision pending" suggests editorial discussion about conflicting reviews

Second-round reviews after revision typically take 4-6 weeks. The journal allows one major revision opportunity for most papers.

Endoscopy's most common desk rejection triggers involve scope mismatch and methodological problems that editors spot immediately.

• Scope-related rejections:

Papers on general gastroenterology without endoscopic focus get rejected within days. The journal won't consider studies of inflammatory bowel disease, hepatology, or nutrition unless they specifically address endoscopic diagnosis or management.

Case reports describing routine presentations also face immediate rejection. Editors want cases that teach new techniques or demonstrate unusual endoscopic findings. Common presentations with typical endoscopic appearances don't merit publication regardless of clinical outcome.

• Methodological problems causing desk rejection:

Single-center retrospective studies with small sample sizes (under 50 patients for most topics) rarely advance to review. The journal favors multicenter studies or single-center studies with substantial patient numbers.

Inadequate control groups in comparative studies trigger rejection. Studies comparing new techniques to "historical controls" or "usual care" without standardized comparators don't meet editorial standards.

• Peer review failure points:

Statistical problems cause many rejections after review. Underpowered studies, inappropriate statistical tests, or missing statistical analysis details lead to rejection even when clinical findings seem interesting.

Inadequate literature review also causes post-review rejection. Reviewers expect comprehensive discussion of previous endoscopic studies and clear positioning of new work within existing knowledge.

• Quality signals that help acceptance:

Multicenter data collection suggests broader applicability. Standardized outcome measures demonstrate methodological rigor. Clear reporting of adverse events shows clinical relevance.

Videos or high-quality endoscopic images strengthen submissions significantly. The journal particularly values visual documentation of novel techniques.

When Endoscopy rejects your paper or doesn't match your research scope, several alternatives offer similar visibility in gastroenterology and endoscopy.

• Gastrointestinal Endoscopy represents your closest alternative. Published by Elsevier for the American Society for Gastrointestinal Endoscopy, it accepts similar article types with slightly broader scope including some general gastroenterology research.

• Digestive Endoscopy provides good visibility in Asian markets and accepts more case reports than Endoscopy. The journal particularly welcomes technical innovations and procedural modifications.

• Endoscopy International Open serves as Thieme's open-access complement to Endoscopy. Papers rejected by Endoscopy often succeed here with lower barriers for case reports and smaller studies.

• For broader gastroenterology research:

World Journal of Gastroenterology accepts endoscopy studies within larger gastroenterology context. American Journal of Gastroenterology works well for studies with strong clinical outcomes data even if endoscopy isn't the primary focus.

• Subspecialty alternatives:

Pancreatic endoscopy studies fit well in Pancreatology or Pancreas. Biliary endoscopy research suits Journal of Gastroenterology and Hepatology. Pediatric endoscopy studies belong in Journal of Pediatric Gastroenterology and Nutrition.

Plan your submission strategy with 2-3 target journals ranked by preference. Different journals favor different study designs and geographic regions, so match your paper's strengths to journal preferences.

Before you upload, run your manuscript through a Endoscopy submission readiness check to catch the issues editors filter for on first read.

In our pre-submission review work with manuscripts targeting Endoscopy, three patterns generate the most consistent desk rejections among the papers we analyze.

In our experience, roughly 35% of desk rejections at Endoscopy trace to scope or framing problems that prevent the paper from competing in this venue. In our experience, roughly 25% involve insufficient methodological rigor or missing validation evidence. In our experience, roughly 20% arise from a novelty claim that outpaces the supporting data.

According to Endoscopy submission guidelines, each pattern below represents a documented desk-rejection trigger; per SciRev data and Clarivate JCR 2024 benchmarks, addressing these before submission meaningfully reduces early-rejection risk.

• General gastroenterology study framed as endoscopy research. Endoscopy's editorial scope, as stated in the Thieme author guidelines, requires that papers report "diagnostic or therapeutic aspects of endoscopy." The failure pattern is a manuscript on inflammatory bowel disease management, hepatology, or nutrition that includes an endoscopic finding as one of several outcome measures, then submits to Endoscopy with that finding highlighted in the cover letter. Editors identify the mismatch immediately: if the primary research question, study design, and analytic framework would be unchanged if the endoscopic component were removed, the paper is out of scope. Papers that succeed here have endoscopy as the procedure under study, not as a diagnostic adjunct to a broader research question. SciRev author-reported data confirms Endoscopy's median first decision at approximately 8-12 weeks, with desk rejections typically in the first 1-2 weeks.

• Single-center retrospective study with inadequate sample size for the claim. Endoscopy reviewers evaluate whether the study design matches the scope of the conclusion. The failure pattern is a single-center retrospective study with 20-40 patients drawing conclusions about technique superiority or safety outcomes that require larger sample sizes to support. Editors are particularly critical when the primary endpoint is a rare outcome (perforation, bleeding, mortality) and the study is underpowered to detect clinically meaningful differences. Papers that survive review in this category typically come from centers with high-volume endoscopy programs or pool data across multiple sites, and they state power calculations explicitly.

Clarivate JCR 2024 bibliometric data provides additional benchmarks when evaluating journal fit.

• Case reports describing common presentations without a novel technique or unusual finding. Endoscopy accepts case reports, but the editorial bar is explicit: the case must demonstrate either a novel endoscopic technique or an unusual presentation that teaches something new about endoscopic diagnosis or management. The failure pattern is a case report of a correctly managed complication or a well-described endoscopic finding where the learning point is "this rare condition can be diagnosed endoscopically." Editors reject these because they provide no new information for practicing endoscopists. Case reports that pass triage include video documentation of a novel technique, a finding that changes how endoscopists should interpret a specific appearance, or a management approach that differs from established protocols in a testable way. A Endoscopy submission readiness check can identify scope fit and study design issues before the submission window.

Editors consistently screen submissions against these patterns before sending to peer review, so addressing them before upload reduces desk-rejection risk.
