Laparoscopic Probe for Sentinel Lymph Node Harvesting Using Magnetic Nanoparticles.

Objective: Sentinel lymph node harvesting is an essential step in the surgical treatment of a growing number of malignancies. Various techniques are available to facilitate this purpose. The present study reports a new laparoscopic technique for lymph node harvesting using magnetic nanoparticles containing a superparamagnetic iron-oxide core and dextran coating.
