Laparoscopic repositioning of chronic gastric volvulus in a dog
Bibliographic record
Abstract
A 12-year-old spayed Newfoundland bitch was presented with chronic non-productive vomiting, regurgitation and coughing of six weeks' duration. On clinical examination, the dog was depressed with no other significant findings. Haematology and biochemistry investigations detected no abnormalities. Thoracic and abdominal radiographs revealed a megaoesophagus and an abnormally positioned pylorus. A thoracic and abdominal computed tomography scan confirmed the abnormal position of the stomach, together with moderate aspiration pneumonia. Laparoscopic examination of the peritoneal cavity revealed the greater omentum wrapped over the stomach, with a fold visualised between the abnormally positioned pyloric antrum and the gastric corpus. A 180-degree clockwise gastric rotation was laparoscopically diagnosed and corrected. The normal position of the stomach was confirmed before a laparoscopic-assisted incisional gastropexy was performed. Post-operatively the vomiting and regurgitation resolved and the patient was discharged. Twenty-four hours after discharge, the dog was presented with deteriorating clinical signs of aspiration pneumonia. The owner declined treatment, additional diagnostics as well as a necropsy and requested euthanasia. Chronic gastric volvulus should be considered as a rare differential diagnosis in dogs with non-specific, chronic gastrointestinal signs. Radiography, computed tomography and laparoscopy are valuable diagnostic aids in making this diagnosis. Chronic gastric volvulus can be successfully reduced laparoscopically as reported here for the first time.

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.
