Magnetic Duodeno-Ileostomy (MagDi)
Magnetic Duodeno-Ileostomy (MagDi) is an innovative, minimally invasive bariatric procedure designed to help patients achieve significant weight loss and improve metabolic health. By utilizing specially designed magnets to create a secure connection (anastomosis) between the duodenum and the ileum, this technique offers a novel approach to weight management without the need for traditional surgical stapling or suturing in the digestive tract.

What Is Magnetic Duodeno-Ileostomy (MagDi)?
Magnetic Duodeno-Ileostomy, commonly referred to as MagDi, is a cutting-edge metabolic and weight loss procedure. Unlike traditional bariatric surgeries that rely heavily on surgical staples or sutures to alter the digestive tract, MagDi uses the power of magnetic compression to create a new pathway for food. This connection, known as an anastomosis, is formed between the upper part of the small intestine (the duodenum) and the lower part (the ileum).
By rerouting the digestive system, the MagDi procedure limits the absorption of calories and nutrients, which may promote weight loss and support improved metabolic function. Magnetic compression anastomosis is designed as an alternative to traditional hand-sewn or stapled connections, without the need for surgical staples or sutures. This procedure is an option for patients seeking a less invasive alternative to traditional Gastric Bypass or Gastric Sleeve surgeries.
How the MagDi Procedure Works
The MagDi procedure is a carefully orchestrated, minimally invasive process that combines endoscopic and laparoscopic techniques. Our experienced bariatric surgeons perform this procedure with precision and care, ensuring the highest level of safety.

The magnets can be placed one of two ways: swallowed and guided into position endoscopically, or placed surgically through small openings in the stomach and small bowel. In the swallowed approach, the process begins in our outpatient department, where you swallow the first specially designed magnet. This magnet travels naturally through your digestive system, first into the stomach, then into the upper part of the small intestine (the duodenum). About two hours later, you are brought into the operating room.
Using advanced laparoscopy, a minimally invasive technique guided by a small camera, our surgical team locates the first magnet and guides it further down to the lower part of the small intestine (the ileum). At the same time, a thin scope is used to place the second magnet into the stomach, then carefully guide it just past the stomach’s lower opening (the pylorus) and into the duodenum. In the surgical approach, both magnets are placed directly through small openings in the stomach and small bowel. Either way, the two magnets are then aligned so they can connect.
Once the magnets connect, they create a strong hold that gently compresses the tissue between them. Our surgical team then closes any small gaps in the surrounding tissue to prevent future complications, and you are moved to the recovery area.
Over the next two to three weeks, steady pressure from the magnets allows the tissue between them to break down naturally, while the surrounding tissue heals and joins together. The material holding the magnets in place dissolves over about two weeks. By the third week, the magnets detach and pass safely into your digestive tract. Your body’s natural digestive motion then smooths this new connection into its permanent shape. The magnets continue through your digestive system and leave your body naturally within 24 to 48 hours.
Benefits of the MagDi Procedure
Choosing the right weight loss surgery is a deeply personal decision. The MagDi procedure offers several unique advantages for patients looking to improve their health and achieve lasting weight loss.
Minimally Invasive Approach
Because MagDi relies on magnetic compression rather than extensive cutting and stapling, it is considered highly minimally invasive. This approach typically results in less trauma to the digestive tissues.
Minimally invasive surgical techniques are associated with reduced postoperative pain, shorter hospital stays, and faster overall recovery times.
Reduced Risk of Leaks
One of the primary concerns with traditional intestinal surgery is the risk of anastomotic leaks at the staple or suture lines. The magnetic compression used in MagDi creates a secure, uniform seal as the tissue heals, which is designed to lower this risk.
Early clinical studies of this magnet-based technique report no anastomotic leaks, bleeding, or strictures, though as with any surgery, other complications can occur. Research is ongoing.
Improvement in Metabolic Conditions
Like other metabolic surgeries, MagDi is designed to help improve or resolve obesity-related comorbidities.
Early studies of this magnet-based technique report improvements in blood sugar control among patients with Type 2 diabetes, though most published research to date involves small patient groups followed over the short term.
By altering how the body processes food, the procedure may help support metabolic health as part of a comprehensive weight loss plan.
Recovery and What to Expect
Recovery from the MagDi procedure is generally smoother and faster than recovery from traditional open surgeries. Because the procedure is minimally invasive, most patients experience only mild discomfort, which can be easily managed with prescribed medications.
Following the procedure, you will be closely monitored by our team. You will begin a carefully structured liquid diet to allow your new digestive pathway to heal. Over the course of several weeks, you will gradually transition to pureed foods, soft foods, and eventually solid foods. Our dedicated nutrition and counseling support team will provide you with a detailed dietary plan to ensure you receive adequate nutrition while maximizing your weight loss results.
During the two to three weeks following the procedure, the magnets will remain in place, doing their work to create the anastomosis. You will not feel the magnets during this time. Once the connection is fully formed, the magnets will pass naturally through your digestive system, typically within 24 to 48 hours after detaching.
Comprehensive lifestyle changes, including dietary modifications and regular physical activity, are essential for maintaining weight loss after bariatric surgery. Our team is committed to providing the ongoing support you need to succeed on your journey.

Frequently Asked Questions
Where can I find the MagDi procedure?
Long Island Laparoscopic Doctors offers the MagDi procedure for patients across Long Island, NY, including Setauket, East Setauket, and Suffolk County. Our Master Surgeons provide unparalleled expertise in a compassionate, supportive environment, ensuring you receive the highest quality care close to home.
How is MagDi different from Gastric Bypass or Gastric Sleeve?
Unlike Gastric Bypass or Gastric Sleeve, the MagDi procedure does not require cutting, stapling, or removing part of the stomach. Instead, two magnets are used to create a new connection in the small intestine. This may make MagDi a good option for patients seeking a less invasive alternative, though your surgeon can help determine which procedure best fits your goals.
How long does the MagDi procedure take?
The MagDi procedure begins with a short outpatient visit, where you swallow the first magnet. About two hours later, our surgical team completes the laparoscopic and endoscopic portion of the procedure. Many patients return home the same day or after a short period of observation.
Will I need to follow a special diet after the MagDi procedure?
Yes. After the MagDi procedure, you will follow a structured diet that gradually progresses from liquids to pureed, soft, and eventually solid foods. Our nutrition and counseling support team will guide you through each stage to support healing and long-term weight loss success.
Is the MagDi procedure covered by insurance?
Coverage for the MagDi procedure varies by insurance plan and individual circumstances. During your consultation, our team can help you explore your coverage options and other ways to make treatment accessible.
Am I a good candidate for the MagDi procedure?
Ideal candidates for the MagDi procedure are adults struggling with obesity, typically those who are approximately 100 pounds overweight with a BMI of 35 or higher, or a BMI of 30 or higher with weight-related comorbidities such as Type 2 diabetes or hypertension. During your consultation, our bariatric surgeons will evaluate your medical history to determine if MagDi is the safest and most effective option for your specific needs.
Is the MagDi procedure reversible?
Yes, the MagDi procedure is reversible. It is similar to a SADI (Single Anastomosis Duodeno-Ileostomy) procedure, but is designed to reduce certain surgical risks associated with traditional stapled or sutured connections. If additional intervention is needed, it can also be converted to a full SADI procedure. Your provider can help determine the best path forward based on your results and goals. If you have had prior bariatric surgery and are experiencing issues, we also specialize in revisional bariatric surgery to provide a continuation of care.
