A Case Report of a Bleeding Duodenal Gastro-Intestinal Stromal Tumor and its Emergent Management
Bibliographic record
Abstract
A gastrointestinal stromal tumor (GIST) arising in the duodenum is a rare subtype of mesenchymal tumor. GISTs have a reported incidence of 11.9–19.6 per million population and duodenal GISTs make up just 5% of these tumors. Common presentation of duodenal GISTs is through an upper gastrointestinal bleed, of which, they are responsible for less than 1% of all gastrointestinal bleeding. In an elective setting, surgical management remains the mainstay of treatment. In this Case Report, the emergent management of a localized duodenal resection was performed by an acute care surgeon, in an unstable patient. The risk factors for malignancy include tumor size and a high mitotic cell index. Tumor recurrence is determined by tumor size, tumor rupture, high mitotic cell index, a non-gastric location and gastrointestinal bleeding.

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.
