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

We aimed to apply the free-viewpoint video technology developed and introduced mainly for sports spectators to an open surgical video recording system. Prospective feasibility study. University of Tsukuba Hospital, Ibaraki, Japan. 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. 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. 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.
