Balloon Occluded Retrograde Transvenous Obliteration of Bleeding Stomal Varices Using Sodium Tetradecyl Sulfate Foam: A Case Report
Bibliographic record
Abstract
Stomal varices can develop secondary to portal hypertension in patients with a stoma. The bleeding is often recurrent and may be fatal with mortality rates of 3–4% (1). Treatment options include 1) direct pressure or ligation (1), 2) direct percutaneous embolization of the feeding portal branch using a coil or of the varix using glue (2, 3), 3) systemic therapy with vasoactive drugs (4), 4) surgical management (1, 5), 5) transjugular intrahepatic portosystemic shunt (TIPS) or balloon occluded retrograde transvenous obliteration (BRTO) (6, 7). We present a patient with recurrent bleeding from a stomal varix that was controlled with BRTO using sodium tetradecyl sulfate (STS) (Omega Laboratories Ltd., Quebec, ONT, Canada) foam.

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.
