Abstract: Background Magnetic anastomosis has the potential to reduce anastomosis complications such as leaks and bleeding, as well as reduce complex procedure steps and time to create a safe anastomosis. We report the procedure feasibility and 30-day results of a new surgical technique and new self-forming nitinol magnetic anastomosis procedure (SNAP-PS) and delivery devices on post-sleeve gastrectomy patients. Methods Prospective non-randomized single-centre trial. Surgery consisted of creating a side-to-side duodenal-ileal anastomosis 300 cm from the IC valve using a new self-forming magnetic (SFM) octagonal anastomosis. The proximal SFM was deployed through the endoscope, and the distal SFM through a 5 mm laparoscopic trocar. Results A total of 3 patients were recruited, with a mean age of 36.3 25–42) years, sex-ratio (100% F) of 100%, and initial BMI of 41.0 ± 1.4 kg/m2. All procedures were performed using a combination of endoscopy and laparoscopy. There was no conversion or peri-operative mortality. All SFMs were delivered and connected with no delivery malfunctions and completed in an anastomosis creation time on average of 30.6 minutes (enterotomy to magnet coupling). 0 procedure adverse events (AE) occurred, and 0 AD occurred during the 30-day follow-up period. All patients tolerated the surgery and were discharged within 24 hours. Conclusion Preliminary and procedural feasibility data for these new devices suggest that SNAP-PS is feasible and safe. Based on prior studies, it provides a minimally invasive surgical option for patients needing additional weight loss and improved comorbidities. Additional follow-up is required.
