Diabetes improvement and bariatric surgery—review of laparoscopic Roux-en-Y gastric bypass vs. laparoscopic vertical sleeve gastrectomy
Bibliographic record
Abstract
Obesity and type 2 diabetes mellitus (T2DM) are globally escalating major health care issues. For both obesity and T2DM management, it has been well established that bariatric surgery is superior to lifestyle and medical management alone. Over the past two decades, the introduction of laparoscopic vertical sleeve gastrectomy (LVSG) has seen a marked rise in usage, and combined with laparoscopic Roux-en-Y gastric bypass (LRYGB), these two procedures represent more than 80% of all bariatric surgeries globally. However, the differences in effectiveness between these two procedures have been less clearly defined. This article will serve as a focused review of the literature comparing LRYGB and LVSG for T2DM management. Based on our review, we believe that both procedures are very effective at improving T2DM care, especially compared with conventional medical management. However, there may be a modest benefit to be had by using LRYGB over LVSG.

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.
