Comparison of da Vinci SP and Xi surgical systems for robotic lateral transperitoneal adrenalectomy: a retrospective single-center observational study

Abstract

Purpose: Robotic adrenalectomy was developed to address the limitations of laparoscopic adrenalectomy and enhance the visualization, dexterity, and control of surgeons performing this beneficial minimally invasive technique.This study compared the clinical and perioperative outcomes of lateral transperitoneal adrenalectomy using da Vinci SP and Xi robotic systems (Intuitive Surgical).Methods: We retrospectively analyzed 84 patients who underwent robotic adrenalectomies at a single institution between January 2019 and July 2024.Sixty-two and 22 patients were treated with da Vinci Xi and SP systems, respectively.Results: No significant differences in patient demographics, tumor size, or postoperative hospital stay between the 2 groups were observed.The SP system demonstrated significantly shorter operative times for right-sided adrenalectomy (81.0 17.1 minutes vs. 113.3 26.2 minutes, P < 0.001), whereas no significant differences were observed in overall operative time (104.9 28.2 minutes for Xi vs. 93.5 23.2 minutes for SP, P = 0.094) or left adrenalectomy (99.9 28.4 minutes for Xi vs. 104.0 23.0 minutes for SP, P = 0.253). Conclusion:The da Vinci Xi and SP systems are both effective for robotic adrenalectomy, with the SP system showing particular advantages in right-sided procedures.
