Free-Viewpoint Video in Open Surgery: Development of Surgical Arena 360

OBJECTIVE: We aimed to apply the free -viewpoint video technology developed and introduced mainly for sports spectators to an open surgical video recording system. DESIGN: Prospective feasibility study. SETTING: University of Tsukuba Hospital, Ibaraki, Japan. PARTICIPANTS: Patients who underwent open pancreaticoduodenectomy for pancreatic cancer between December 2022 and March 2023 were included. The gastrojejunal anastomosis was the subject of the recording. RESULTS: Four surgeries were recorded with Surgical Arena 360, which is the free -viewpoint video system that we developed. The feasibility of performing a series of surgical procedures without interrupting the surgeon's line of sight or manipulation was demonstrated in all cases. CONCLUSIONS: Our study revealed that Surgical Arena 360, an open surgical video recording system developed by applying free -viewpoint video technology, can provide new insights into surgical support and clinical knowledge to surgeons by enabling secure capture of the open surgical field from multiple angles.
