Endoscopic Ultrasound–Guided Choledochoduodenostomy With Lumen-Apposing Metal Stent Through Duodenal Stent, a Success Case, and a Salvage Case
Bibliographic record
Abstract
Endoscopic ultrasound-guided choledochoduodenostomy (EUS-CD) has become a feasible alternative technique in cases of malignant bile duct obstruction, especially when the endoscopic retrograde cholangiopancreatography is not feasible or has failed. In the case of duodenal obstruction, when a duodenal stent has been initially placed, performing endoscopic retrograde cholangiopancreatography could be quite difficult with a low success rate. Thus, EUS-CD could be a good alternative. In this study, we present 2 particularly challenging endoscopic cases in which EUS-CD was performed with a lumen-apposing metal stent inserted through a previously placed duodenal stent.

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.
