Biliary atresia and survival into adulthood without transplantation: a collaborative multicentre clinic review
Bibliographic record
Abstract
BACKGROUND: Biliary atresia is a progressive biliary injury which occurs only in infants. AIMS: To review the experience of patients surviving into adulthood without the need for liver transplantation in childhood. METHODS: A multicentre review of patients with biliary atresia treated surgically who survived into adulthood without the need for transplantation. RESULTS: Twenty-two patients were identified across four centres. Median age at the last follow-up was 25 years (range: 18-46), and 21 patients had clinical features of portal hypertension. At last follow-up values of liver enzymes varied from normal to 15 × the upper limit of normal (ULN) for ALT (median 2.11 × ULN) and 9 × the ULN for ALP (median 2.02 × ULN). Six patients had a serum bilirubin > 50 μmol/l. Pruritus and jaundice were noted in 8 of 20 patients (40%) and 11 of 22 patients (50%) respectively. Thirteen patients (59.1%) were shown to have imaging features of sclerosing cholangitis, with strictures of intrahepatic bile duct(s) (IHBD), dilatation of IHBD (n = 8), or stone(s) within the IHBD (n = 5). A history of presumed bacterial cholangitis was present in 11 patients (50%). Successful pregnancies were recorded in three of fourteen female patients. Four patients underwent transplant between the ages of 20-27 years. Twenty-one patients (95.5%) were alive, including 18 (81.8%) with their native liver at the time of last follow-up. CONCLUSIONS: Some patients treated for biliary atresia will survive into adulthood with their native liver, but commonly with secondary biliary disease including cholangitis and portal hypertension.

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.
