In this scenario, laser speckle contrast imaging (LSCI) is a non-invasive imaging technique that uses laser light to detect the landmark prostatic artery pathway, facilitating NVB plane identification and dissection. This technology illuminates the tissue and detects the contrast of the speckle pattern caused by the movement of blood cells. METHODS: We performed LSCI on 28 patients undergoing RARP. Intraoperatively, LSCI was performed using a laser speckle contrast imaging system ActivSight™ (Activ Surgical, Boston, MA) attached to a laparoscopic scope. The NVB was identified by visual inspection using white light from the robotic camera and then imaged using LSCI. The imaging was performed by positioning the LSCI laparoscopic scope over the area of interest and obtaining real-time images of the tissue perfusion. The images were analyzed using custom software to extract information on blood flow velocity and vessel diameter. RESULTS: Using LSCI, we were able to identify the landmark artery in all patients. In some cases, the landmark arteries were identified using regular white light, and the LSCI helped identify the prostatic artery in cases that were not evident with the standard robotic scope. In cases where nerve preservation was intended on the specific side, the landmark artery was also visualized after dissection. CONCLUSIONS: This demonstrative proof of concept highlights the feasibility and potential utility of LSCI in identifying the prostatic artery and facilitating the NVB dissection during RALP.
