Early Re-Initiation of Semaglutide Post Sleeve Gastrectomy in Youth

This is a Phase 3a, randomized, parallel-controlled trial designed to compare the early re-initiation of semaglutide, starting two weeks after sleeve gastrectomy, to standard care (no pharmacotherapy following surgery). The trial will involve 150 youth with severe obesity who have been on semaglutide 2.4 mg weekly for at least 3 months prior to surgery. Participants will be randomized to either (1) semaglutide 2.4 mg weekly or (2) standard care for 24 months. Primary, secondary, and tertiary outcomes will be assessed at multiple time points: 1-month, day of surgery, and 1-, 3-, 6-, 9-, 12-, 18-, and 24-months postoperatively. We hypothesize that early re-initiation of semaglutide will be safe, well-tolerated, and lead to greater improvements in obesity, cardiometabolic risk, and eating behaviors.

Tailored One Anastomosis Gastric Bypass

One Anastomosis Gastric Bypass (OAGB) is the most common metabolic and bariatric surgery (MBS) in Israel, recognized for its effectiveness in achieving sustainable weight loss and mitigating obesity-related diseases. The metabolic outcomes of OAGB are significantly influenced by the length of the biliopancreatic limb (BPL). The objective of this study is to determine whether tailoring the BPL length to the total small bowel length (TSBL) results in more effective weight loss compared to patients undergoing OAGB with a fixed BPL of 180 cm. Efficacy and safety of this approach will also be evaluated, ensuring it does not lead to long-term morbidity or negatively impact patients' quality of life.
