PROCEDURE

Magnetic Gastric Bypass

PROCEDURE

Magnetic Sleeve Gastrectomy

PROCEDURE

Nissen/Sleeve Gastrectomy with Magnetic Assistance

Perform a nissen-sleeve gastrectomy with the magnetic grasper performing the liver retraction and the upper retraction of the stomach, retraction of the stomach to close the hiatal defect and perform a nissen funduplication before do the sleeve gastrectomy

PROCEDURE
