Abstract
Background
To compare the perioperative and short-term efficacy and cost of the da Vinci Xi and da Vinci Si surgical systems for radical prostatectomy.
Methods
We retrospectively analyzed the clinical data of 175 patients with prostate cancer who underwent radical prostatectomy with the da Vinci Si or Xi surgical systems in our hospital from June 2019 to June 2020. Of the 175 patients, 82 underwent robot-assisted laparoscopic radical prostatectomy with the da Vinci Xi surgery system, and 93 patients underwent robot-assisted laparoscopic radical prostatectomy with the da Vinci Si surgical system. The perioperative outcomes, short-term efficacy and costs were compared between the two groups.
Results
The anesthesia time, operation time, docking time, indwelling catheter time and postoperative bed rest time in the Xi group were shorter than those in the Si group (respectively, 268.8 min vs. 219.3 min, P = 0.001; 228.2 min vs. 259.6 min, P < 0.001; 7.4 min vs. 12.7 min, P < 0.001; 8.6 d vs. 9.7 d, P = 0.036; 2.2 d vs. 2.6 d, P = 0.002). However, the total cost of hospitalization and the cost of intraoperative consumables in the Xi group were higher than those in the Si group (84,740.7 vs. 76,739.1 ¥, P = 0.003; 13,199.4 vs. 10,823.0 ¥, P = 0.019).
Conclusions
Although the cost of robot-assisted radical prostatectomy is higher, compared with the Si system, the Xi system has better perioperative outcomes and can provide similar short-term efficacy and oncology outcomes.
