Feasibility of a Novel Robotic Surgical System for Partial Gastrectomy in a Porcine Model

Background This preclinical study evaluated the safety and technical feasibility of robot‐assisted partial gastrectomy (RPG) using the Carina Platform in a porcine model to accumulate evidence for clinical translation. Methods Six pigs underwent RPG (4 with Plan A, 2 with Plan B setups). The acute group ( n = 3) were euthanised 1‐h postoperation, while the chronic group ( n = 3) survived 28 days for recovery assessment. Operative parameters (time, blood loss), complications, and ergonomics (NASA‐TLX) were recorded. Necropsy evaluated surgical site healing. Results All procedures were successfully completed. Mean operative time was 109 ± 34 min. One intraoperative liver injury was controlled without complications. The chronic group showed no infections, with necropsy confirming recovery. Surgeons reported favourable ergonomic scores. Conclusion RPG using the Carina Platform is safe and technically feasible in porcine models, supporting future clinical trials.
