Application of the da Vinci surgical robot system in presacral nerve sheath tumor treatment

Abstract

The aim of the present study was to investigate the feasibility of da Vinci robotic surgery in the treatment of presacral tumors, and to observe its efficacy and safety. Between March 2016 and April 2019, 12 patients with presacral nerve sheath tumors underwent da Vinci robotic surgery, and the integrity of the tumor resection, surgical duration, pre- and postoperative visual analog scale (VAS) score, intra- and postoperative blood losses, postoperative bedtime, hospital stay and complications were observed. The tumor was completely removed in all 12 patients, the surgical duration ranged between 76 and 245 min (mean, 106.08 min) and the intraoperative blood loss was 76-145 ml (mean, 101.67 ml). The average preoperative VAS score of the patients was 3.25, and the average VAS score at 1 week, 1 month and 3 months post operation were 1.08, 0.42 and 0.08, respectively. All patients were out of bed on the second day after surgery, and the postoperative drainage was 10-50 ml (mean, 33.50 ml). The patients were hospitalized for 3-5 days (mean, 3.92 days). No complications occurred peri- or postoperatively, and wound pain was the main source of postoperative discomfort. In conclusion, the da Vinci robot can be applied to presacral nerve sheath tumors with high surgical safety, low-level bleeding, a rapid recovery and a short hospital stay, making it worthy of further study.
