Abstract

Abstract : INTRODUCTION: Head-mounted mixed-reality technologies may enable advanced intraoperative visualization during visceral surgery. In this technical note, we describe an innovative use of real-time mixed reality during robotic-assisted transanal total mesorectal excision. TECHNIQUE: Video signals from the robotic console and video endoscopic transanal approach were displayed on a virtual monitor using a head-up display. The surgeon, assistant, and a surgical trainee used this technique during abdominal and transanal robotic-assisted total mesorectal excision. We evaluated the feasibility and usability of this approach with the use of validated scales. RESULTS: The technical feasibility of the real-time visualization provided by the current setup was demonstrated for both the robotic and transanal parts of the surgery. The surgeon, assistant, and trainee each used the mixed-reality device for 15, 55, and 35 minutes. All participants handled the device intuitively and reported a high level of comfort during the surgery. The task load was easily manageable (task load index: <4/21), although the surgeon and assistant both noted a short delay in the real-time video. CONCLUSION: The implementation of head-mounted mixed-reality technology during robotic-assisted transanal total mesorectal excision can benefit the operating surgeon, assistant, and surgical trainee. Further improvements in display quality, connectivity, and systems integration are necessary. Abstract : Supplemental Digital Content is available in the text.
