Laparoscopic sleeve gastrectomy is an independent predictor of poor follow-up and reaching ≤ 40% excess body weight loss at 1, 2, and 3 years after bariatric surgery.

LSG remained an independent predictor of poor weight loss at all post-operative time points. Furthermore, the risk of experiencing poor weight loss was significantly higher following LSG compared to LRYGB for patients with high-risk characteristics.
