Evaluation of a gasless device in robot-assisted cholecystectomy in a canine model

Introduction Laparoscopic gasless surgery is a minimally invasive approach that avoids CO₂ insufflation to create the pneumoperitoneum. This study analyzes the use of a novel novel device for gasless surgery during robot-assisted cholecystectomy in canine model. Material and Methods Three canine cadavers from previous studies were used. Two animals underwent robot-assisted cholecystectomy with a gasless surgery device, while the third underwent conventional robot-assisted cholecystectomy. The gasless device consists of a base, an articulating frame and a set of supports for grasping forceps. The VersiusTM robotic platform (CMR Surgical) with a Maryland bipolar dissector and a monopolar hook was used in all surgeries. Results All three surgeries were performed successfully, with a similar surgery time of 29.297 ± 9.571 minutes. The device for gasless surgery was feasible in both animals, but required initial setup time in order to elevate the abdominal wall and create working space. Once achieved, the device remained stable throughout the procedure. Evacuation of gases during the use of energy instruments is a consideration. Conclusions Preliminary results demonstrate the feasibility and safety of the novel device for gasless surgery in combination with robotic-assisted surgery. This study offers innovative alternatives to mitigate the physiological complications associated with pneumoperitoneum in conventional surgery.
