Abstract
BackgroundTo compare the perioperative and short-term efficacy and cost of the da Vinci Xi and da Vinci Si surgical systems for radical prostatectomy.MethodsWe 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.ResultsThe 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).ConclusionsAlthough 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.
Highlights
As the most common malignant tumor in men, prostate cancer is a serious health threat [1]
The worldwide mainstream da Vinci Si robotic surgical system has been favored by the majority of urologists because of its good vision, flexible robotic arms and excellent oncology outcomes [3]
All operations were performed by four urologists in our center who have been using the Si surgical system to perform urological operations since 2014; all surgeons had a wealth of experience in using robot systems to perform such operations
Summary
As the most common malignant tumor in men, prostate cancer is a serious health threat [1]. There are many treatments for prostate cancer, including castration therapy, endocrine therapy, radiotherapy, chemotherapy and surgery. Radical prostatectomy is considered the best method for the treatment of localized prostate cancer, especially for patients with a life expectancy of more than 10 years [2]. Compared to open radical prostatectomy, traditional laparoscopic surgery has less blood loss and fewer complications and has many shortcomings, such as the limited range of surgical instruments. The Si system has many advantages over laparoscopy, with the continuous improvement of urologists’ requirements for surgical instruments, its shortcomings are gradually being magnified, such as the long docking time, easy friction between robotic arms, and lack of tactile feedback.
