A Rare Case of Anterograde Gastroduodenal Intussusception Caused by Migrated Percutaneous Endoscopic Gastrostomy Feeding Tube
Bibliographic record
Abstract
Gastroduodenal intussusception is a critical condition in which stomach protrudes into the duodenum. It is a very rare condition in adults. Most common causes include intra luminal lesions in the stomach including benign or malignant tumors of the stomach. Most common tumors included are gastrointestinal stromal tumors (GISTs), gastric carcinoma, gastric lipoma, gastric leiomyoma, and gastric schwannoma. It is extremely rare to be caused by migration of percutaneous feeding tube. A 50-year-old woman with a past medical history (PMH) of dysphagia status post percutaneous endoscopic gastrostomy (PEG) tube, history of spastic quadriplegia, presented with acute nausea, vomiting and abdominal distention, and was found to have gastroduodenal intussusception in computed tomography (CT) scan. Condition resolved after retracting PEG tube. Endoscopy did not reveal any intra luminal lesions. External fixation using Avanos Saf-T-Pexy T-fasteners was performed to prevent recurrence of this condition. Most common of causes of gastroduodenal intussusception are GIST tumors of stomach. CT abdomen is the most accurate test and upper endoscopy is needed to rule out any intra luminal causes. Treatment of choice is either endoscopic or surgical resection. External fixation is essential to prevent recurrence.

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.
