Abstrakt: Background: Less invasive and safer anastomotic techniques are desirable. We aimed to determine technical feasibility and safety of sutureless duodeno-ileal side-to-side anastomosis in obese patients using self-assembling magnets.
Methods: This was an open-label, prospective, and single-arm study including obese patients (BMI 30-50 kg/m 2 ) with type II diabetes. The ileal magnet was deployed laparoscopically, and the duodenal magnet was deployed endoscopically. Both magnets were coupled under laparoscopic and fluoroscopic guidance. The primary endpoints were technical feasibility and safety. The secondary endpoints were patency of the anastomosis, HbA1c reduction, and weight loss 12 months after the procedure.
Results: A total of 8 patients were enrolled in the study; median age was 51.5 years (range: 34-65), and median BMI was 38.8 kg/m 2 (range: 35-47.9). The mean procedural duration was 63.5 min (range: 41-95). No intraoperative complications were recorded, and no major postoperative morbidity related to the procedure occurred. Magnets were expelled at a median of 29.5 days after the procedure with no associated complications. Upper endoscopy at 12 months confirmed patent anastomoses with healthy-appearing mucosa in all patients. HbA1c reduced below 7.0% in 6 out of 8 (75%) patients, and greater than 5% of total body weight loss was observed in 7 out of 8 (87.5%) patients at 12 months.
Conclusions: Sutureless duodeno-ileal side-to-side anastomosis using self-assembling magnets is feasible and safe in obese patients, and a dual-path enteral diversion with large-caliber and durable anastomosis can be achieved.
