ABSTRACT
Purpose@#The da Vinci SP robotic surgical system (Intuitive Surgical) offers pure SP with 4 lumens, which accommodates the fully-wristed endoscope and 3 arms with multijoint feature. We herein present our initial experience of the da Vinci SP surgical system in robotic single-site cholecystectomy. @*Methods@#Thirty consecutive patients with a preoperative diagnosis of gallstones and/or chronic cholecystitis who underwent robotic SP cholecystectomy (RSPC) using da Vinci SP surgical system from January to May 2019 were reviewed.The perioperative outcomes were assessed and compared with those performed using Si-robotic single-site surgical system. @*Results@#Mean docking time was 5.2 minutes. The mean actual dissection time was 14.6 minutes while the mean operation time was 75.1 minutes. Postoperative course was unremarkable and patients were discharged after a mean hospital stay of 1.5 days. In comparative analysis, operation time (109.5 ± 30.0 minutes vs. 75.1 ± 17.5 minutes, P = 0.001), docking time (11.9 ± 4.3 minutes vs. 5.2 ± 1.9 minutes, P = 0.001), actual dissection time (34.6 ± 18.4 minutes vs. 14.6 ± 5.1 minutes, P = 0.001), console time (58.7 ± 23.0 minutes vs. 32.4 ± 11.6 minutes, P = 0.001), immediate postoperative pain (4.6 ± 1.3 vs. 3.2 ± 1.0, P = 0.001), and pain prior to discharge (2.0 ± 0.6 vs. 1.4 ± 0.0, P = 0.002) were significantly improved in RSPC. @*Conclusion@#RSPC is feasible, safe, and effective. The perioperative outcomes are better compared with Si-robotic singlesite surgical systems.
ABSTRACT
The da Vinci surgical system released its new pure single-port platform, the da Vinci SP, offering improvements and refinements for established robotic single-site procedures. Herein, we present the first case of robotic single-site cholecystectomy using the da Vinci SP system (RSPC) demonstrating its safety and technical feasibility. A 59-year-old female with chronic calculus cholecystitis was admitted for elective RSPC. Docking time took 6 minutes. The patient underwent successful RSPC with a total operation time of 89 minutes. There was no significant intraoperative event. The patient had unremarkable postoperative course. Multijoint instruments, simple docking process, and third-arm functionality are among the RSPC's advantages. Absence of the port for an assistant surgeon can be a hindrance in performing more complicated surgeries. The present case suggests that RSPC is safe and feasible. The promising features and potential application of da Vinci SP in hepatobiliary and pancreas surgery need further study.
