Prevalence and Predictive Factors of Histopathological Complications in Children with Esophageal Atresia
Bibliographic record
Abstract
Objectives Endoscopic follow-up after esophageal atresia (EA) tracheoesophageal fistula (TEF) repair is recommended to detect esophageal histopathological complications. We investigated the prevalence of histopathologically proven esophageal complications (peptic esophagitis, gastric metaplasia, and eosinophilic esophagitis) and assessed the predictors of these complications in children with EA-TEF. Materials and Methods This is a prospective longitudinal cohort study performed between September 2005 and December 2014 comprising 77 children with EA-TEF followed-up until February 2017. Univariate analysis was performed using the Wilcoxon's rank-sum test for continuous variables and the Pearson's chi-square test for categorical variables. Multivariable analysis was performed using a Cox regression hazard model. The association between clinical factors and histopathologically proven complications was estimated using a Cox regression hazard model with time until the appearance of complications as the time scale. Results All 77 children received proton pump inhibitors (PPIs) (n = 73) or H2 receptor antagonists (H2RA). A total of 252 endoscopies were performed in 73 children (median 2.6/child, range: 1–29). Median age at study completion was 4.9 years (range: 2.3–11.5 years). Histopathologically proven complications occurred in 38 children (52%): peptic esophagitis (n = 32, 44%), eosinophilic esophagitis (n = 15, 21%), and gastric metaplasia (n = 9, 12%). A total of 82% patients were on PPI or H2RA at the time of diagnosis of histological complication. Multivariable Cox regression analysis showed that patients with recurrent anastomotic strictures (>3 dilations) had a higher risk of occurrence of histopathologically proven complications over time (hazard ratio: 3.11, 95% confidence interval [CI]: 1.53–6.34). On univariate analysis, the result of the first endoscopy was not associated with the occurrence of histopathologically proven complications (odds ratio: 0.8, 95% CI: 0.16–3.95). Conclusion Histopathologically proven complications with potential long-term consequences occurred in approximately 50% of children after EA-TEF repair. A history of recurrent anastomotic strictures is associated with the occurrence of these complications. The result of the first endoscopy does not predict the histopathological outcome. Children with EA-TEF warrant close and systematic long-term follow-up at specialized multidisciplinary clinics with endoscopic evaluation.

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.
