Initial experience with the Carina™ platform in robotic-assisted hysterectomy for gynecological malignant disease

Abstract

Objective: This retrospective study was performed to evaluate the efficiency and safety of a new modular robotic system, the Carina™ Platform (Ronovo Surgical, Shanghai, China), in gynecological surgery. Methods: All patients underwent robotic hysterectomies (RH) using the Carina performed by a single gynecologist experienced in laparoscopic and robotic surgery from November to December 2023. Patients were evaluated for estimated blood loss (EBL), intraoperative and postoperative complications, length of hospital stay, conversion rate, as well as console and docking times. Results: Two separate populations were involved: 10 cervical cancer patients (group 1) and six endometrial cancer patients (group 2). There were no conversions to laparotomies or laparoscopies. The mean docking time was 5.75 ± 2.38 min. The mean console time and mean operative time were 154.60 ± 26.01 min and 211.90 ± 53.65 min in group 1, respectively. The mean console time and mean operative time were 98.67 ± 26.71 min and 153.33 ± 22.77 min in group 2, respectively. The median estimated blood loss for group 1 and group 2 were 30 ml (20, 50) and 20 ml (7.5, 20), respectively. No intraoperative or postoperative complications related to the device were recorded. Conclusion: Our experience allows us to state that the modular Carina Platform is safe and efficient in complex gynecologic surgery.
