Surgical Workflow and Skill Analysis based on Navigation System Information

Advanced and complicated surgical procedures impede normal surgical management and place a burden on surgeons and hospitals. Quantitative analysis and prediction of surgical workflow/progress contributes to an understanding and improvement of surgical procedures, environments, and effective scheduling.

For the optimal management of surgery, it is quite important to know the progress of the surgical procedure, whether the progress is satisfactory, and when the procedure will be finished during the surgery itself. We are developing a method for the process progress analysis of surgical procedures. We have developed the first prototype for the process progress analysis of glioma surgery, which can indicate the progress rate and the expected finish time of tumor removal. We applied this system for clinical cases in the iMRI OR at the Tokyo Women's Medical University (TWMU).

Furthermore, we now try to apply the system to endoscopic surgeries. An endoscopic surgery, which is performed through small incisions, requires high specialized skills. Optimizing surgical procedures and enhancing surgical skills are very important for the safety of endoscopic surgeries. Therefore, we have developed a surgical workflow analysis system for endoscopic surgeries, which allows surgeons to understand the process progress as well as whether the procedure is properly performed and what the surgeon should improve if points to be improved are found during the procedure. So far, we have created and validated an application to quantitatively evaluate and visualize surgeon's skill level and surgical process during laparoscopic cholecystectomy.
