Laparoscopic Resection of Central Ovarian Cancer Recurrence in the Pelvis Utilizing a Fluorescent Ureteral Near-Infrared Ray Catheter (NIRC): A Case Report.

The central recurrence of ovarian cancer at the vaginal stump requires anterior pelvic resection if there is an invasion into the bladder triangle. There is a lack of evidence regarding the efficacy of minimally invasive surgery for recurrent ovarian cancers. Therefore, there are no reports of using a fluorescent ureteral near-infrared ray catheter (NIRC) (Cardinal Health Ltd., Tokyo, Japan) in laparoscopic surgery for recurrent ovarian cancers. We reported a 51-year-old woman who underwent laparoscopic resection for recurrent ovarian cancer located on the posterior wall of the vaginal stump, exposed to the vaginal lumen, and invaded the rectum but not the anterior vaginal wall or bladder. A fluorescent ureteral NIRC for the real-time intraoperative visualization of the ureters allowed laparoscopic resection of the recurrent tumor at the vaginal stump with preservation of the bladder and the ureters.
