Transradial left gastric artery embolization to treat severe obesity: A pilot study
Bibliographic record
Abstract
BACKGROUND: Bariatric surgery is currently the only effective treatment with long-lasting results to treat severe obesity. OBJECTIVES: We performed a pilot study to evaluate the feasibility, safety and efficacy of percutaneous distal embolization of the left gastric artery (LGA) using a transradial approach. METHODS AND RESULTS: . We successfully injected 300-500 μm polyvinyl alcohol particles using 5Fr catheters and all distal LGA were occluded at the end of procedures. Mean procedure duration was 24 ± 13 min and mean fluoroscopy time was 10 ± 5 min. Six patients reported mild transient epigastric discomfort, which resolved with proton pump inhibitors. At 2 months, the average weight loss was of 7 ± 6 kg (median loss: -10 kg [-2, -11]), 6 ± 12 kg (median loss: -9 kg [-16, +4]) at 6 months and 13 ± 17 kg (median loss: -11 kg [0, -25]) up to 12 months after index procedures. CONCLUSION: Percutaneous transradial LGA embolization appears to be a promising technique to reduce the obesity burden. Randomized trials are required to further delineate the risk/benefit ratio, potential clinical indications and long term results.

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.
