Biodegradable biliary stents placement using a “kissing‐stent” technique for management of a recalcitrant stricture post‐live donor liver transplant
Bibliographic record
Abstract
BACKGROUND: Biliary complications are common in pediatric liver transplant. Strictures resistant to interventional radiology procedures can be extremely challenging to manage and may result in the need of surgery or retransplantation. METHODS: This case report illustrates the use of biodegradable stents post left lateral segment live donor liver transplant in a pediatric patient with a recalcitrant chronic stricture of the biliary-enteric anastomosis. The patient developed a high stricture requiring multiple interventions and eventual access of both the segment II and segment III ducts of the graft. RESULTS: To ensure adequate biliary drainage, two biodegradable stents were deployed using a "kissing-stent" technique. The stents were successfully deployed and allowed the patient to remain free from an internal-external biliary drain for 11 months, with eventual redeployment of an additional biodegradable stent. CONCLUSION: In patients with recalcitrant stenosis of the biliary anastomosis, biodegradable stents may provide durable drainage, optimizing graft function and delaying retransplantation in addition to keeping patients without external devices, thus improving quality of life.

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.
