Gastric Outlet and Duodenal Obstruction as a Complication of Migrated Gastrostomy Tube: Report of Two Cases and Literature Review
Bibliographic record
Abstract
Percutaneous endoscopic gastrostomy (PEG) is a well-recognized procedure for providing enteral feeding and long-term enteral nutritional support. Although it is mostly well tolerated, complications, sometimes mechanical in nature, do occur. Rare, and often initially unrecognized, late complications of PEG tube placement are gastric outlet obstruction and duodenal obstruction. Simple adjustment of the gastrostomy tube will lead to the improvement of the patient's clinical condition and prevent further complications. Physicians should be aware of and suspect gastric outlet and duodenal obstruction as rare late complications of PEG tube placement. Simple adjustment of the gastrostomy tube can resolve the problem without unnecessary medical tests and overly aggressive care. Here, we present two interesting cases of elderly women who developed mechanical obstruction after inadvertent migration of the gastrostomy tube.

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.
