Transvaginal liver surgery using a tethered magnet and a laparoscopic rein

A novel technique was used to remove a large liver cyst via culdolaparoscopy.

We used laparoscopic instruments, a gastroscope, a laparoscopic rein, and magnets. The magnets consist of an external magnet and a specially modified tethered neodymium internal magnet, safe for use in transvaginal endoscopic surgery.

These technologies offer some advantages when they are used together: magnets and the rein to aid in exposure, traction-retraction, and triangulation. Previous reports have been published on the removal of benign liver lesions transvaginally, but none to date has involved the use of magnets. This article reports on the role of magnets and reins in an incision reduction approach to the removal of a liver cyst.
