Pre‐pouch ileitis after colectomy in paediatric ulcerative colitis
Bibliographic record
Abstract
UNLABELLED: Colectomy and ileal pouch anal anastomosis (IPAA) is a potentially curative option for patients with ulcerative colitis (UC). A rare, postoperative complication is terminal ileitis which has been poorly documented in paediatric patients. A search of our paediatric inflammatory bowel disease (IBD) database revealed two boys with UC who were resistant to medical therapy. They each underwent colectomy with IPAA. One year later, both children represented with bloody diarrhoea and weight loss. Several endoscopies and biopsies showed acute on chronic mucosal inflammation in the pouch and up to 50 cm into the terminal ileum (TI). Biopsies revealed mixed inflammatory infiltrate with no granulomas. CONCLUSION: Development of terminal ileitis after colectomy and IPAA can occur in children with UC. Although every effort should be made to exclude Crohn's disease as a cause of the terminal ileitis, this poorly defined condition should not be considered to be against the diagnosis of UC. More research is needed to develop a better understanding of the aetiopathogenesis of this uncommon condition.

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.
