Abstract
Objective
To implement and test the feasibility of an image-guidance system for robot-assisted radical prostatectomy (RARP). Laparoscopic surgical outcomes may be improved through image guidance. However, to demonstrate improved outcomes rigorous evaluation techniques are required. Therefore we also present our work in establishing robust evaluation techniques.
Patients and Methods
Development work used three cadavers and an anatomy phantom. The system has been used on 13 patients.
During surgery the surgeon can refer to the patient's magnetic resonance imaging (collected before the operation) overlaid on the endoscopic video image.
The result of the overlay process was measured qualitatively by the surgeon with reference to the desired clinical outcomes.
Results
The use of the overlay system has not resulted in any measurable change in clinical outcomes.
The surgeons found the system to be a useful tool for reference during surgery.
A more rigorous evaluation method is proposed that will enable on-going development.
Conclusion
Image guidance during RARP is feasible. We propose a series of measures that will improve further development and evaluation.
