A Simple Endoscopic Score Modified for the Upper Gastrointestinal Tract in Crohn’s Disease [UGI-SES-CD]: A Report From the ImageKids Study
Bibliographic record
Abstract
OBJECTIVE: There is no standardized endoscopic description of upper gastrointestinal [UGI] disease in Crohn's disease [CD]. We prospectively applied the Simple Endoscopic Score for CD [SES-CD] to the UGI tract as a planned sub-study of the multicentre prospective ImageKids study. We aimed to assess the utility of the UGI-SES-CD and its clinical significance in paediatric CD. DESIGN: Patients underwent an oesophagogastroduodenoscopy [EGD], ileocolonoscopy, and magnetic resonance enterography [MRE] with explicit clinical data recorded. SES-CD was scored at each region [oesophagus, stomach body, antrum, and duodenum]. Half of the patients were followed for 18 months, when a repeat MRE was performed. RESULTS: A total of 202 children were included 56% males, mean age 11.5 ± 3.2 years, median weighted Paediatric Crohn's Disease Activity Index [wPCDAI 25]). UGI-SES-CD score ranged 0-17, with 95 [47%] having a UGI-SES-CD ≥1; no narrowing was detected. UGI-SES-CD ≥1 was associated with higher: wPCDAI [32.5 vs 20; p = 0.03]; Physician's Global Assessment [PGA] of inflammation (45 mm visual analogue score [VAS] vs 30 mm VAS; p = 0.04); ileocolonoscopic SES-CD [10 vs 7; p = 0.004], faecal calprotectin [717 µg/g vs 654 µ/g; p= 0.046]; and radiological global assessment of damage by MRE [7 mm VAS vs 0; p = 0.04]. In all, 81 patients were followed for 18 months and no association was identified between initial UGI SES-CD and markers of disease course such as surgery, MRE assessment, or treatment escalation. CONCLUSION: UGI-SES-CD is an easily reported objective scoring system and is associated with a more severe disease phenotype but not with disease course.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
