The present study evaluates an innovative solution through the use of magnetic devices that are coupled and mobilized by external magnetic fields through the abdominal wall. To evaluate a new magnetic surgical system during reduced-port gastric sleeve surgery


This magnetic surgical system is an innovative technological platform that utilizes magnetic retraction designed to grasp and retract tissue and organs. It is composed by a grasper device with a detachable tip and a magnetic controller.


We operated 23 patients, 16 women and 7 men. Age range between 17 and 62, with an average of 35,8 years old. The BMI range was between 30 and 38,3 with a media of 33,4 Kg/m2. All of them had comorbidities such as insulin resistance, dyslipidemia, arterial hypertension, hypotyroidism, arthralgia, non alcoholic fatty liver disease or obstructive sleep apnea. The mean operative time was 1:42 hours. All of them were fully performed by a reduced port technique. Reduced port means that we used 3 ports, when we generally need 4 or 5. Magnetic grasper was used to retract the stomach and the liver. Average stay of 2 days and no intraoperative or postoperative complications.


This novel technology is safe. It allows a greater exposure in reduced port laparoscopic surgery. It is very easy to manipulate because its shape and function are equal to a regular grasper, and it can be utilized with a minimal learning curve.
