Feasibility of a Minimally Invasive Image-Guided Surgery System for Hepatic Procedures

Stopped early

Conditions studied: Liver Cancer

In brief

This study was designed to confirm that the surgeon is able to perform accurate liver surface registration including standard liver features used as landmarks during a scheduled laparoscopic liver procedure. The hypothesis is that there will be no clinically relevant difference between the error measurements obtained during the laparoscopic procedures in this study when compared with those obtained during previous open liver registration studies. The surface of the liver will be manually swabbed with the study tracked laparoscopic probe with landmarks noted during data collection. After registration of the liver is obtained, the registration points obtained during this procedure will be evaluated by the surgeon by moving the tracked laparoscopic probe over the liver surface and evaluating the location of the tracked laparoscopic probe displayed on the guidance system three dimensional (3D) image. The surgeon will accept or reject the registration accuracy.
