Intraoesophageal migration of Teflon pledgets used for hiatal hernia repair: a serious adverse event
Bibliographic record
Abstract
11 months following an elective paraoesophageal hernia repair, a female patient presents to the emergency department with severe dysphagia. A CT showed a distention of the distal oesophagus caused by a foreign body and dense material inside and outside the oesophagus wall. A gastroscopy confirmed the presence of a bezoar and secondary oesophagitis due to the intraoesophageal migration of Teflon pledgets. Even when used appropriately, only for the crus repair, the use of Teflon pledgets may result in fistulisation through the oesophagus. This complication suggests that the use of Teflon pledgets to buttress a hiatal hernia repair should be used with caution and that an alternative technique (eg, resorbable pledgets) could be preferred.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
