Magnetic anchoring guidance systems (MAGS) are composed of an internal surgical instrument controlled by an external handheld magnet and do not require a dedicated surgical port. Therefore, this system may help to reduce internal and external collision of instruments associated with laparoendoscopic single-site (LESS) surgery. Herein, we describe the initial clinical experience with a magnetically anchored camera system used during laparoscopic nephrectomy and appendectomy in two human patients.


Two separate cases were performed using a single-incision working port with the addition of a magnetically anchored camera that was controlled externally with a magnet.


Surgery was successful in both cases. Nephrectomy was completed in 120 min with 150 ml estimated blood loss (EBL) and the patient was discharged home on postoperative day 2. Appendectomy was successfully completed in 55 min with EBL of 10 ml and the patient was discharged home the following morning.


Use of a MAGS camera results in fewer instrument collisions, improves surgical working space, and provides an image comparable to that in standard laparoscopy.
