Magnet surgery: a new way to treat obesity and diabetes?
NCT ID NCT06232746
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a new magnetic device that creates a connection between two parts of the small intestine, bypassing some of the digestive tract. The goal was to see if this procedure is safe and feasible for adults with obesity and type 2 diabetes. Only 9 people took part, and the study focused on whether the device could be placed correctly and create a working connection without major complications.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Magnetic anastomosis device (DI Biofragmentable Magnet System)
- What this could lead to
- If successful, this could offer a less invasive surgical option to help with weight loss and improve blood sugar control in people with obesity and type 2 diabetes.
- What could go wrong
- This is a very small, early feasibility study with only 9 participants. The device may not work as intended, and there are risks like bowel perforation, obstruction, or bleeding. Long-term benefits are unknown.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. 18-65 years of age, inclusive, at the time of informed consent 2. BMI 30-40 kg/m2 3. T2DM (defined as HbA1c ≥ 6.5%) without previous sleeve gastrectomy and without plan to perform a concurrent sleeve gastrectomy 4. Agrees to refrain from any type of additional bariatric or reconstructive surgery that would affect body weight for the duration of the study 5. If a child-bearing female, subject must commit to not becoming pregnant and agree to use contraception for the duration of the study 6. Willing and able to comply with protocol requirements Exclusion Criteria: 1. Type 1 diabetes 2. Use of injectable insulin 3. Uncontrolled T2DM 4. Plan to perform a sleeve gastrectomy with the jejuno-ileal anastomosis procedure 5. Uncontrolled hypertension, dyslipidemia or sleep apnea 6. Prior intestinal, colonic or duodenal surgery, other than bariatric 7. Prior surgery, trauma, prostheses, disease or genetic expression which prevent or contra-indicate the procedure, including scarring and abnormal anatomy. 8. Refractory gastro-esophageal reflux disease (GERD) 9. Barrett's disease 10. Helicobacter pylori positive and/or active ulcer disease 11. Large hiatal hernia 12. Inflammatory bowel or colonic diverticulitis disease 13. Any anomaly precluding orogastric access by gastroscope and catheters, and manipulation techniques. 14. Implantable pacemaker or defibrillator 15. Psychiatric disorder, except well-controlled depression with medication for \> 6 months 16. History of substance abuse 17. Woman who is either pregnant or breast feeding 18. Woman of childbearing potential who does not agree to use an effective method of contraception. 19. Any comorbidity or current status of subject's physiological fitness that in the surgeon's or anesthesiologist's opinion represents safety concerns that make the subject medically unfit for the procedure, including any significant congenital or acquired anomalies of the GI tract at or distal to the placement of the magnets. 20. Unhealed ulcers, bleeding lesions, tumor, or any other lesion at target magnet deployment site 21. Expected need for MR imaging within the first 2 months after the procedure 22. Any anomaly preventing/contraindicating endoscopic or laparoscopic access and procedures 23. Had surgical or interventional procedure within 30 days prior to procedure 24. Any scheduled surgical or interventional procedure planned within 30 days postprocedure 25. Any stroke/TIA within 6 months prior to consent 26. Requires chronic anticoagulation therapy (except aspirin) 27. Active infections requiring antibiotic therapy, unless resolved before undergoing the study procedure 28. Unable to comply with the follow-up schedule and assessments 29. Recent tobacco or nicotine product cessation within \< 3 months prior to informed consent 30. Known allergies to the device components or contrast media 31. Limited life expectancy due to terminal disease 32. Currently participating in another clinical research study with an investigational drug or medical device 33. Any condition that, in the investigator's opinion, may preclude completion of followup assessments through Day 360 (e.g., a medical condition that may increase the risk associated with study participation or may interfere with interpretation of study results, inability to adhere to the visit schedule, or poor compliance with treatment regimen)
