The Magnetic Anchoring and Guidance System (MAGS) consists of an internal surgical device coupled across the abdominal wall and manipulated using an external handheld magnet. This video demonstrates a MAGS cautery dissector used in a cadaveric human cholecystectomy model. The gallbladder was retracted percutaneously and one laparoscopic instrument was used for assistance. The MAGS instrument was used to perform the entire dissection (18 minutes). The MAGS dissector provided excellent triangulation, obviated the need for additional laparoscopic instruments, minimized instrument conflicts, was compatible with human anatomical considerations, and greatly facilitated the single site approach.
