Tube Migration Leading to Gastric Outlet Obstruction: An Unusual Complication of Percutaneous Endoscopic Gastrostomy
Bibliographic record
Abstract
Percutaneous endoscopic gastrostomy (PEG) placement is a well-established technique for administering long-term enteral nutrition. Gastric outlet obstruction is a rare complication of gastrostomy tube placement caused by migration of the tube into pyloric channel or duodenal bulb. A 72-year-old female presented with complaints of nausea and abdominal pain after recent PEG placement. The diagnosis of tube migration leading to gastric outlet obstruction was made after the inflated Mickey balloon was visualized obstructing the pyloric channel. The Mickey tube was carefully extracted with an endosnare. Early recognition of the tube migration leading to obstructive symptoms in a clinically appropriate scenario prevents further complications such as ulceration, necrosis and avoids surgical intervention.

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.
