Short-term outcome analysis of Carina™ platform in gastric and colorectal surgery: A single-group target-value clinical trial

Objective

To systematically evaluate the efficiency and safety of the Carina™ Platform (Ronovo Surgical, Shanghai, China) in the field of general surgery, this study reported our preliminary experience.

Methods

Twenty-six consecutive patients were scheduled to undergo Carina robot-assisted laparoscopic surgery in our units from December 2023 to July 2024. The factors analyzed were the time required to prepare the patient and the room, total time of surgery, length of specimens, number of lymph nodes retrieved, blood loss, complications, and post-operative results.

Results

This robot-assisted laparoscopic surgery system is safe and mature. All of procedures were completed robotically, and there was no conversion to laparotomy. The median operation time was 172.5 ​min (range, 125–375) and the mean (SD) number of lymph nodes retrieved was 24 (9). The median docking time was 10 ​min (range, 6–15). The incidence of surgical complications was 2 out of 26 cases, including one patient with a rectal anastomotic leak and another patient with a wound infection.

Conclusions

The use of the Carina modular robotic system in gastric and colorectal surgery has been demonstrated to be both effective and safe. However, the advantages of modular robotic platforms remain to be explored, and further research is needed to assess long-term outcomes.
