Surgical resection of arteriovenous malformation of the pancreatic head with acute pancreatitis: a case report
Bibliographic record
Abstract
Arteriovenous malformations (AVMs) are uncommon in the gastrointestinal tract, particularly in the pancreas. AVMs cause complications, including gastrointestinal bleeding, portal hypertension and pancreatitis. Therefore, a treatment strategy is not yet established. Surgical treatment or transcatheter arterial embolization is performed in patients with AVM, considering their conditions. A 54-year-old man presented with acute abdominal pain was diagnosed with acute pancreatitis due to AVM of the pancreatic head using dynamic computed tomography. Endoscopic ultrasonography further revealed meandering blood vessels in the pancreatic head. The patient underwent subtotal stomach-preserving pancreaticoduodenectomy. Histological examination revealed AVM of the pancreatic head with chronic pancreatitis. The patient had a good postoperative clinical course and was discharged on postoperative day 22. He remained asymptomatic. Pancreaticoduodenectomy can be considered an effective treatment method for selected cases of symptomatic AVM of the pancreatic head.

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.
