Interventional radiology-assisted transgastric endoscopic drainage of peripancreatic fluid collections
Bibliographic record
Abstract
Summary: Peripancreatic fluid collections (PFCs) occur as a consequence of pancreatitis. Most PFCs resolve spontaneously, although 1%-2% persist and may require intervention. Conventional transluminal endoscopic drainage methods require the PFC to be bulging into the gastric wall; however, it is not uncommon for this to be absent. Imaging guidance for transluminal endoscopic PFC drainage allows the endoscopist to localize nonbulging pseudocysts that cannot be localized using endoscopy alone, to identify and avoid vascular structures between the cyst and the gastric lumen, and to reveal solid or necrotic components within the pseudocyst cavity. Although endoscopic ultrasound (EUS) has been used to meet this need, timely access to therapeutic EUS remains a limiting factor at many centres. We report our technique and experience performing transgastric endoscopic drainage of PFCs under computed tomography (CT) interventional radiology guidance.

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.
