Routine Elective Gastrojejunostomy Tube Changes Are Associated With Reduced Tube Complications and Radiation Exposure
Bibliographic record
Abstract
Gastrojejunostomy tubes (GJTs) can be a long-term solution for patients with intragastric feeding intolerance. Our retrospective study of 101 patients correlates the frequency of routine and urgent GJT changes, as well as complications and radiation exposure. Over a 2.75-year median duration, 60%, 33%, and 28% of patients had >1 episodes of a tube dislodgement/malpositioning, blockage, or leakage, respectively. Aspiration pneumonia hospital admission was required for 23% of patients. Patients with <1 routine tube change/year had more urgent changes/year (3.0) compared to patients with 1-2 (1.2) or >2 (0.8) routine yearly change. These patients required more frequent sedation for tube placement (21% vs 4.7%, P = 0.03) and experienced greater annual radiation exposure (9599 vs 304.5 and 69.1 μGym 2 , P = 0.01 and 0.008, respectively). Overall, aiming for a routine tube change at least every 6-12 months is associated with fewer urgent changes and complications as well as reduced radiation exposure and sedation requirements.

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.
