Duodenal ganglioneuromatosis causing common bile duct obstruction in a dog
Bibliographic record
Abstract
A 3‐year‐old intact female labrador retriever dog was presented for anorexia, weight loss and vomiting. Abdominal ultrasonography revealed a mass of the descending duodenum involving the major duodenal papilla with loss of the normal intestinal wall layering. The distal part of the common bile duct was circumferentially thickened obliterating its lumen and causing extrahepatic biliary obstruction. Exploratory laparotomy was undertaken, total descending duodenum excision with gastrojejunostomy, cholecystojejunostomy and pancreaticojejunostomy procedures were performed. The dog died 3 days postoperatively. Histopathological and immunohistochemistry examinations of the specimens from the duodenectomy demonstrated multinodular to diffuse intestinal ganglioneuromatosis. This is the first reported case of an intestinal ganglioneuromatosis, a rare hyperplastic proliferation of ganglion cells and nerves of the enteric autonomic nervous system, involving the duodenum and causing extrahepatic biliary obstruction.

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.
