Preoperative Total Abdominal Fat Area (TAFA) is an independent predictor of excellent weight loss outcomes following laparoscopic sleeve gastrectomy, with lower TAFA predicting higher likelihood of achieving >75% excess weight loss and >30% total weight loss.
If you are considering sleeve gastrectomy, ask your surgeon about measuring your abdominal fat area (via CT or MRI) before surgery. A lower abdominal fat area is associated with a significantly higher chance of achieving excellent weight loss results. This metric offers more predictive power than BMI alone.
Total abdominal fat area (p = 0.033) and BMI (p = 0.003) were independent predictors of %TWL ≥30%. ... it was determined that a lower abdominal fat area independently predicted excellent weight loss outcomes 1 year postoperatively in our cohort [OR: 0.996 (95% confidence interval: 0.993–0.998), p = 0.001].
Why this rating
Retrospective cohort study with a validation set, showing statistical significance (p<0.05) and good model calibration, but limited by single-center design and small sample size.
