Portland Debuts Next-Gen Magnetic Bariatric Surgery
As a site for magnetic anastomosis duodeno-ileostomy (DI) bypass, Adventist Health Portland is helping advance a new generation of bariatric care focused on less invasive surgical innovation. The procedure uses magnets to create a connection within the small intestine rather than traditional stapling or suturing. Once the connection forms, the magnets naturally pass through the body without leaving a permanent implant behind. Early studies have shown promising outcomes for weight loss and diabetes improvement, while reducing some of the operative risks like bleeding and leaks when making new connections. This technology results in shorter, safer surgery. Additionally, it is fully reversible and creates the important hormone changes in the body that lead to durable weight loss without some of the downsides of traditional bariatric procedures.
Published clinical studies reported successful creation of the connection in all study patients, with no device-related leaks, bleeding, or infections in early cohorts. Researchers are also continuing to study newer minimally invasive approaches and long-term outcomes as the technology evolves.
For patients, the innovation is not simply about new technology, it is about expanding access to additional treatment options that may better fit individual health goals and recovery needs. As obesity and diabetes rates continue to rise nationwide, emerging procedures like magnetic DI bypass represent an important area of advancement in metabolic and bariatric medicine. Adventist Health Portland’s participation as a pilot site reflects its commitment to bringing leading-edge therapies to the region while maintaining rigorous clinical oversight and patient safety standards. The procedure is preformed using DaVinci robotic surgical technology to provide a minimal invasive approach to surgery and is often done in just 3 tiny incisions.
The program combines advanced surgical techniques with long-term multidisciplinary support, including nutrition counseling, behavioral health resources, and ongoing follow-up care. Like all bariatric procedures, patient selection, education, and lifelong support remain critical to achieving successful outcomes and improving overall health.
“Bariatric surgery continues to evolve rapidly, and magnetic anastomosis technology is one of the most exciting advancements we’ve seen in years,” said Dr. Ryland Stucke. “As a pilot site, we have the opportunity to help evaluate innovative approaches that may improve recovery and outcomes while continuing to prioritize the highest standards of patient safety and quality care.”
Innovation at Adventist Health Portland is paired with a strong focus on quality and safety. The program received American College of Surgeons Comprehensive Center for Obesity Medicine in 2025. They were also named an Aetna Institute of Quality® bariatric facility, a United Healthcare Center of Excellence in Bariatrics and received a Blue Distinction from Blue Cross Blue Shield .
