Complication of a Percutaneous Endoscopic Gastrostomy Tube Causing Duodenal Ischemia
Bibliographic record
Abstract
A 33-year-old woman with a percutaneous endoscopic gastrostomy tube was admitted with bilious vomiting, 1 month after her feeding tube was replaced by a temporary Foley catheter. A computed tomography scan of her abdomen revealed a 4.5 cm by 7.5 cm fluid-filled structure in the distal duodenum surrounding the Foley feeding tube. Approximately 100 mL of fluid was aspirated from the Foley's balloon port. We hypothesized that the Foley catheter was flushed inappropriately through the balloon port, causing an iatrogenic ischemic duodenal injury. Conservative management was successful in the intensive care unit. This case highlights an unusual complication of percutaneous endoscopic gastrostomy tubes. In addition, it emphasizes the temporary nature of Foley catheters as replacement gastrostomy tubes, and the importance of training in the handling of feeding tubes.

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.
