Case 273: Pancreatic Duct–to–Portal Vein Fistula with Secondary Portal Vein Pyophlebitis—A Rare Complication of Chronic Pancreatitis
Bibliographic record
Abstract
History A 55-year-old man with a history of chronic pancreatitis secondary to chronic alcohol abuse presented to the hospital with acute abdominal pain, generalized weakness, weight loss, and pyrexia. A clinical examination revealed he was tender to touch in the upper abdomen. Laboratory tests revealed a serum alkaline phosphatase level of 370 U/L (6.1 µkat/L) (normal range, 30–130 U/L [0.5–2.2 µkat/L]), a lipase level of 172 U/L (2.9 µkat/L) (normal range, 0–60 U/L [0–1.0 µkat/L]), a C-reactive protein level of 159 mg/L (1514 nmol/L) (normal value, <8.0 mg/L [76.2 nmol/L]), and a white cell count of 7 × 109/L (normal range, [4–11] × 109/L). During the present admission, the patient underwent urgent CT for his acute symptoms. His relevant medical history included a hospital admission 2 months earlier for abdominal discomfort. Given his history of chronic pancreatitis, baseline abdominal MRI was performed to determine the cause of his symptoms and to assess the pancreas.

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.
