MagDI™ (Magnetic Duodeno-Ileostomy) is a groundbreaking approach to hypoabsorptive weight loss surgery. This new FDA-cleared procedure utilizes advanced Magnetic Compression Anastomosis (MCA) to create a suture-free, staple-free ileal bypass in the digestive system.

Sleeve gastrectomy is paired with a side-to-side duodeno-ileal (DI) bipartition to deliver enhanced weight loss and marked improvements in metabolic health, offering patients a path to wellness with fewer risks and a faster recovery.

What is the MagDI System?

MagDI Side to Side Magnetic Duodeno Ileostomy in Tijuana Mexico
Side-to-Side Linear Magnetic Duodeno-Ileostomy (MagDI) is an advancement in bariatric surgery that uses magnetic compression anastomosis to create a union between two parts of the small intestine without cutting, stapling, or stitching at the site.

Patients have reported an average excess weight loss of ~70–75% at 12 months postoperatively.

This paradigm shift, developed by GT Metabolic, consists of a pair of powerful, self-aligning magnets that gently compress and fuse the intestinal tissue. A naturally secure connection is gradually (over a few weeks) formed, creating a new pathway for food to travel. Having served their purpose, the magnets are naturally passed through the digestive tract.

A study looked at a group of patients after one year of GT MagDI surgery. Showed 100% success in magnetic placement and no complications, and improvement in diabetic patients. This study’s 1-year results demonstrate that the MagDI procedure is technically reliable and notably safe, with mild but statistically significant weight loss, and exhibits promising benefits for the management of Type 2 diabetes.

MagDI represents a less invasive, forward-thinking option for patients seeking long-term weight loss solutions with a reduced risk of complications. Magnetic Duodeno-Ileostomy can be performed as a stand-alone procedure or as a revision of a gastric sleeve. MagDI is reserved for individuals with obesity classified as class II and III.

How is MagDI performed?

MagDI Bipartition procedure is performed in a combination of laparoscopy and endoscopy, cooperative surgery. A sleeve is created by surgically resecting a portion of the stomach. Then, the duodenum is joined to the distal ileum (the lower part of the intestine) with a less invasive magnetic technique. The slow compression of magnets creates the fusion of two parts of the intestine over a few weeks. No magnets are left behind, as the biofragmentable magnets are naturally expelled during the healing process.

Details of Operation

  1. The procedure begins in the Outpatient Department, where the patient ingests the first (distal) magnet. This magnet travels naturally through the stomach and duodenum, advancing past the Ligament of Treitz.
  2. After two hours, the patient is brought to the operating room. A laparoscopic procedure is initiated to capture the first magnet with a positioning device and guide it to a more distal location in the ileum. Simultaneously, a second (proximal) magnet is introduced via gastroscopy into the antrum of the stomach. This second magnet is then advanced into the duodenum to a position approximately 2 cm beyond the pylorus. The two segments of the intestine are brought together in an anticolic manner, allowing the magnets to attract and clamp the intervening tissue, thereby creating a future connection. The minor mesenteric defect is then closed, and the patient is transferred to the ward for recovery.
  3. Over the subsequent two to three weeks, the pressure from the magnets causes the trapped tissue to undergo necrosis. The magnets are held together by an absorbable material that dissolves within this period. At approximately two to three weeks, the magnets pass through the newly formed opening (anastomosis) into the distal lumen. This initially oval-shaped anastomosis is gradually remodeled into a circular shape by natural peristalsis. Once they have passed through the anastomosis, the joined magnets travel through the cecum, transverse colon, and left colon, typically reaching the rectum for expulsion within 24 to 48 hours.

6 Benefits of MagDI Magnetic Duodeno Ileostomy -Mexico Bariatric Center

Benefits of MagDI

Here are six key benefits of Magent-Assisted Intestinal Union:

  1. Lower risk of complications: Early clinical trials reported no leaks or bleeding.
  2. Minimally invasive: No cutting or piercing of the small intestine is required.
  3. Stronger, natural healing: The technique encourages uniform healing and a durable connection.
  4. Future surgical flexibility: Preserves intestinal anatomy, allowing for potential reversals or additional procedures.
  5. Faster recovery: Most patients return home the same day or the following morning, based on the surgeon’s recommendation.
  6. Biofragmentable Magnets: These magnets break down after the anastomosis is formed. This means there is no need for a second endoscopic procedure to remove them.

MagDI Comparison to Other Bariatric Procedures

MagDI Comparison Chart to Traditional Weight Loss Surgeries - Mexico Bariatric Center

Gastric Sleeve (VSG): A surgical procedure that removes a portion of the stomach. MagDI can be added to boost weight loss by creating malabsorption.

Gastric Bypass (RNY): This procedure creates a small stomach pouch and reroutes the upper part of the small intestine. MagDI is less invasive and more effective.

Mini Gastric Bypass: The mini gastric bypass is similar to RNY but uses one less connection. MagDI is more effective and has less risk of complications.

Ileal Metabolic Surgeries:

  • BPD/DS: Stomach restriction + distal intestinal bypass. MagDI offers the same hormonal benefits with fewer nutritional deficiencies.
  • SADI-S: Simplified version of BPD/DS with one anastomosis. MagDI produces the same results with less invasiveness.
  • SASI-S: Combines sleeve and mini bypass with more effective results. MagDI establishes the side-by-side connection using a more straightforward technique.

The duodenal switch class of surgeries combines stomach restriction with intestinal bypass to create strong weight control and metabolic effects. However, it also has a higher risk of nutritional deficiencies and surgical complexity.

Pros vs. Cons of MagDI

Pros:

  • Minimally Invasive: MagDI is a less invasive alternative to traditional bariatric surgery, using magnets instead of staples or sutures to create the connection.
    The procedure can lead to weight loss and improvement in T2DM by altering hormone levels and reducing calorie absorption.
  • Revision Option: MagDI can be used as a revision option for the gastric sleeve
  • Manage Type 2 Diabetes: According to a study, over half of obese patients with Type 2 diabetes either reduced or eliminated their diabetes medications by 9–12 months after MagDI.

Cons:

  • Potential Complications: Although generally considered safe, possible complications may include diarrhea and nutrient deficiencies if not managed through dietary changes and supplementation.
  • Few clinical results are available: Researchers are currently conducting clinical trials to evaluate MagDI’s long-term safety and efficacy.
