Laparoscopic sleeve gastrectomy (LSG) provides 60–70% excess weight loss and 50–60% type 2 diabetes remission at 5–7 years, with efficacy comparable to Roux-en-Y gastric bypass (RYGB) and superior safety for super-obese patients (BMI > 60).
Sleeve gastrectomy is currently the most common and effective surgical option for severe obesity, offering significant long-term weight loss and diabetes remission rates comparable to more complex bypass surgeries, with a strong safety profile especially for patients with very high BMI.

Longitudinal gastric resection provides 60–70 % of excess body weight loss (EWL) within 5–7 years and remission of type 2 diabetes in 50–60 % of cases, comparable with the results of gastric bypass surgery. For patients with superobesity, this technique remains highly effective and safe.
Why this rating
Based on RCTs (SLEEVEPASS), meta-analyses, and large registry data (Dutch registry, >2900 patients).
