Magnetic Surgery Duodeno-Ileostomy
MagDI™ System

What is Magnetic Surgery Duodeno-Ileostomy (DI)?

Magnetic Surgery Duodeno-Ileostomy is an innovative, minimally invasive procedure that enhances weight loss and metabolic health by modifying the digestive process using advanced magnetic anastomosis technology. It offers a promising surgical option for individuals with obesity and type 2 diabetes, serving as a less invasive alternative (without traditional surgical cuts, sutures, or staples) to traditional weight loss surgeries like gastric bypass or as part of a staged approach to procedures such as SADI-S (Single Anastomosis Duodeno Ileal Bypass with Sleeve Gastrectomy)

How Does It Work?

This procedure uses magnetic compression anastomosis without incisions, sutures, or staples to create a direct side-to-side connection between the duodenum (the first part of the small intestine) and the ileum (the last part of the small intestine). Because only a portion of the food bypasses the normal digestive pathway, this approach reduces the risk of severe malnutrition, making it a safer initial option.

✅ Significant Weight Loss – By modifying nutrient absorption and gut hormone response.
✅ Diabetes & Metabolic Benefits – Enhancing insulin sensitivity and blood sugar control.
✅ Minimally Invasive Surgery – Using laparoscopic techniques with a magnetic device, reducing scarring and recovery time.

Benefits of Magnetic DI Surgery

✅ Less Invasive – Unlike gastric bypass or sleeve gastrectomy, this procedure does not involve removing part of the stomach.
✅ Faster Recovery – Patients typically experience shorter hospital stays and quicker return to normal activities.
✅ Preserves Anatomy – Unlike other bariatric procedures, the stomach and intestines remain intact.
✅ Promotes Natural Hormonal Changes – Improving appetite regulation and metabolic function.
✅ Potential Reversibility – If needed, the magnetic connection can be closed with staples, providing flexibility for long-term management.

What to Expect Before & During Surgery

Before Surgery

✔️ Comprehensive Evaluation – Your medical team will assess your health, weight, and metabolic status.
✔️ Preoperative Preparation – Dietary and lifestyle modifications may be recommended before surgery.

✔️ Initial Magnet Placement – You will be guided to drink and swallow the first small magnet 3 hrs. before the procedure and have abdominal X-rays to check position in the bowel

During Surgery

✔️ The procedure is performed endoscopically to place a second magnet in the first portion of the duodenum and laparoscopically assisted to connect the two magnets to create a precise, secure connection between the duodenum and ileum.
✔️ The surgery typically takes 1 hour with minimal incisions.

Who is a Candidate?

This procedure may be an option if you:

✔️ Have a BMI of 35+ or a lower BMI with metabolic conditions like type 2 diabetes.
✔️ Have struggled with traditional weight loss methods (diet, exercise, medications).
✔️ Want a less invasive alternative to gastric bypass.
✔️ Are looking for a potentially reversible weight loss solution.

An evaluation with our team will help determine if this procedure is right for you.

Recovery & Results

✔️ Most patients go home the same day.
✔️ Gradual diet progression from liquids to solids over a few weeks.
✔️ The connection between the duodenum and the ileum will get completed by itself with the magnets in about 3 weeks and then weight loss occurs steadily, along with improvements in diabetes and metabolic health.

Frequently Asked Questions (FAQs)

❓ How is Magnetic DI Surgery different from gastric bypass?
It does not involve cutting or rerouting the stomach like gastric bypass. Instead, it uses magnetic technology to create a controlled, reversible connection between different sections of the small intestine.

❓ Is this a permanent procedure?
It is potentially reversible, making it a more flexible option than traditional bariatric surgeries.

❓ Will I need to take vitamins after surgery?
Since food bypasses part of the intestine, some patients may need nutritional supplements to prevent deficiencies. Your doctor will provide guidance.

❓ How much weight can I expect to lose?
Patients typically experience substantial weight loss [30%] within the first year, along with improved metabolic health.

❓ Are the Magnets approved by the FDA?
The MagDI™ System was cleared for use in magnetic compression anastomosis by the U.S. Food and Drug Administration (FDA) in 20241

❓ Is the procedure covered by insurance?
Because is a new procedure, most of insurance companies would not cover it, but we offer a very affordable self-pay option because is an outpatient procedure.
