Abstract

fetched live from OpenAlex

Minimally invasive surgery may be further advanced with the novel biofragmentable magnetic anastomosis compression system. Two magnets may be swallowed, or placed by flexible endoscopy, in a side-to-side magnetic jejuno-ileostomy (MagJI) bipartition for weight and type 2 diabetes (T2D) reduction. MagJI markedly reduces the major complications of enterotomy, stapling/suturing, and retained foreign materials. This was a prospective first-in-human investigation of feasibility, safety, and preliminary efficacy in adults with body mass index (BMI, kg/m 2 ) ≥ 30.0– ≤ 40.0. After serial introduction via swallowing or endoscopy, linear magnets were laparoscopically guided to the distal ileum and proximal jejunum where they were aligned. Magnets fused over 7–21 days forming jejuno-ileostomy. Primary endpoints: feasibility and severe adverse event (SAEs) incidence (Clavien-Dindo grade); secondary endpoints: weight, T2D reduction. Between 3–1 - 2024 and 6–30 - 2024, nine patients (mean BMI 37.3 ± 1.1) with T2D (all on T2D medications; mean HbA1 C 7.1 ± 0.2%, glucose 144.8 ± 14.3 mg/dL) underwent MagJI. Mean procedure time: both magnets swallowed, 86.7 ± 6.3 min; one magnet swallowed with second delivered endoscopically, 113.3 ± 17.0 min. Ninety-day feasibility confirmed in 100.0%: 0.0% bleeding, leakage, infection, mortality. Most AEs grade I–II; no SAEs. At 6-month radiologic confirmation, all anastomoses were patent. Excess weight loss 17.5 ± 2.8 kg; mean BMI reduction 2.2 ± 0.3, HbA1 C 6.1 ± 0.1% ( p < 0.01), glucose 115.5 ± 6.5 mg/dL ( p = 0.19); 83.0% dropped below 6.5% HbA1 C and had markedly reduced anti-T2D medications. The swallowable, biofragmentable magnetic anastomosis system appeared to be feasible and safe in achieving incisionless, sutureless jejuno-ileostomy. The first-in-human MagJI procedure may offer minimally complicated anastomosis creation and moderate MBS weight loss and T2D reduction.

Not 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.
