Barium Retention Following Examination for Pylorus Stenosis
Bibliographic record
Abstract
Barium retention is a rare complication of upper gastrointestinal tract examination when using barium sulphate as a contrast agent. We present a case of rare barium retention and precipitation in the stomach in terrain of chronic gastrostasis and the review of literature on complications of barium sulphate administration. A 38-year-old patient was diagnosed with benign pylorostenosis. After consulting radiology department barium contrast-enhanced X-ray has been indicated. The diagnostic process and the resulting treatment of the complications are described. Patient's informed consent was obtained. The use of barium sulphate as a contrast agent led to stasis and impaction of the contrast agent, which led to emergency surgery. Histology proved malignant stenosis of the pylorus. The resection edges proved insufficient and a repeated resection was performed. At the time of submission the patient has no confirmed metastatic lesions. In cases of suspected gastrostasis and serious stenosis of the intestine, use of barium sulphate should be avoided and iodine-based contrast agents should be used instead.

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.
