Diagnostic Characteristics of Given Video Capsule Endoscopy in Diagnosis of Celiac Disease: A Meta-Analysis
Bibliographic record
Abstract
BACKGROUND AND AIMS: In the view of small sample sizes of the studies published so far, the value of video capsule endoscopy (VCE) in diagnosing celiac disease (CD) is yet to be determined. The aim of this work was to systemically determine the overall diagnostic characteristics of VCE in diagnosing noncomplicated CD, compared to the gold standard, using meta-analysis. PATIENTS AND METHODS: An extensive literature search was performed looking for prospective, controlled trials, with investigators blinded to results of the pathology of small-bowel biopsies. Two independent authors performed data extraction and assessment of the methodologic quality of each trial. Diagnostic characteristics of each trial were collected, and pooled sensitivity, specificity, likelihood ratios, and diagnostic odds ratios were computed. Description of complications and costs was included, if reported. RESULTS: A total of three studies met the inclusion criteria (n = 107; 63 with CD and 44 without). The overall pooled VCE sensitivity was 83% (95% confidence interval [CI] = 71-90%) and specificity was 98% (95% CI = 88-99.6%). No major complications were reported. The costs were mentioned only in one study. CONCLUSIONS: The overall diagnostic characteristics of VCE, when used to diagnose celiac disease, though good with an experienced eye, could not justify the routine use of VCE as an alternative to the pathology of small-bowel biopsies. More studies are needed with proper cost-benefit analysis.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
