Abstract
Gallbladder torsion is a rare cause of abdominal pain; however, it is important to diagnose pre-operatively. We report two cases of gallbladder torsion, both of which were not recognized until the time of surgery. Both patients were elderly thin females, presenting with right upper quadrant pain, and on examination had a positive Murphy's sign, and pre-operative imaging was suggestive of acalculus cholecystitis. One patient was initially managed by percutaneous insertion of a cholecystostomy tube, with progression to a laparoscopic cholecystectomy after a failure of resolution of symptoms. The second patient was taken to theater shortly after presentation, with the gallbladder torsion recognized intra-operatively. In both cases, the gallbladder was distorted and a routine laparoscopic cholecystectomy was performed with good recovery following. These two cases highlight the need for gallbladder torsion to be considered as a diagnostic possibility in those presenting with right upper quadrant pain, particularly those groups at most risk, including elderly thin females. Whilst other causes of cholecystitis can be managed non-operatively, at least in the acute phase, gallbladder torsion requires urgent operative intervention.

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 it
