Jejunal intussusception: a cause of upper gastrointestinal bleeding?
Bibliographic record
Abstract
Intussusception is an important cause of abdominal pain in the paediatric population and is the most common abdominal emergency in early childhood. Intussusception in adults is, however, rare and can lead to diagnostic challenges for admitting physicians/surgeons. We present a case of a 76-year-old lady with history of a recent myocardial infarction and vasculitis presenting with melaena and bleeding per rectum, with suspicion of haematochezia. She complained of abdominal pain but was not clinically obstructed. Gastroscopy performed was negative. Colonoscopy was attempted; however, it was inconclusive because of active bleeding. A CT angiogram of the abdomen was performed, which showed a jejunal intussusception. There was no evidence of vasculitis or small bowel obstruction. She was not considered fit for surgery and was managed conservatively.

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.
