Magnetic devices have been successfully used in bariatric surgery. To the date the only reported use of the magnet was for liver retraction. This study is to demonstrate the safety and viability of using the magnetic system as a second surgical assistant in bariatric surgery and not only for liver retraction.


Patients undergoing primary laparoscopic sleeve gastrectomy (SG), one-anastomosis gastric bypass (OAGB), and Roux-en-Y gastric bypass (RYGB) or revisional surgery by single-port or port-reduced approach.

Also others procedures like Nissen/Sleeve gastrectomy or general surgery. The magnetic system can be used like a second assistant in the steps of the surgery for example: liver retraction, upper retraction of gallbladder, retraction of the stomach, upper retraction of jejuno-jejunal anastomosis performing a gastric bypass or closing mesenteric defects liker intermesenteric or Petersen´s defect.

Using the single-port device or port-reduced approach to obtain better aesthetic results.
