Abstract
The purpose of this study was to evaluate the feasibility and validity of a modified single-port robotic lightweight endoscope in the performance of single-port hysterectomy with pelvic lymph node dissection in the porcine model. Task completion times were recorded for each component of the procedure: port placement, docking of the surgical robot, operative time for the procedures. For each task, linear regression modeling was performed using SPSS to determine whether a correlation existed between task completion time and increasing surgeon experience. All robotic-assisted LESS procedures were performed successfully without the addition of laparoscopic ports or open conversion. Regression analysis demonstrated a strong correlation between the number of procedures and task completion time for robot docking and pelvic lymph node dissection, correlation coefficients 0.74 and 0.77, p = 0.001, respectively. This study demonstrated the feasibility and effectiveness of a new, compact single-port robotic voice-activated endoscope at improving laparoscope guidance during the performance of single-port hysterectomy with pelvic lymph node dissection in the porcine model. Further work is needed to better define the ideal operative procedure for single-site surgery in oncology and integration of new single-port robotic platforms into clinical practice.
