[Long term outcomes after bariatric and metabolic surgery].

At long (=5 years) and very long term (=10 years) bariatric and metabolic surgery (BMS) is the only treatment that allows a significant and durable weight loss concomitant with a control of the different obesity related diseases. Regardless of the surgical technique, BMS significantly decrease long-term mortality (-30% at 15 years). The maximum weight loss is reached at postoperative year 2. Beyond, a weight regain and is usually observed in all procedures. The variability of long-term outcomes underlines the importance of multidisciplinary care throughout follow-up. In 2017, Roux-en-Y-gastric bypass and sleeve gastrectomy were the most popular bariatric procedures and seem to have comparable long-term outcomes.
