Assessment of total mesorectal excision through combined peritoneal and anal approaches in an animal model with Carina™ platform

This study assessed the feasibility of performing hybrid transabdominal and transanal total mesorectal excision using the Carina™ platform in an animal model. The experiment was conducted in a porcine model, where two experienced surgeons performed simultaneous abdominal and transanal portions of the procedure. The procedure was successfully completed in 123 ​min with minimal blood loss of 15 ​mL. Both teams reached the peritoneal reflection without complications or conversion to laparotomy. The Carina™ platform's modular design enabled precise, flexible manipulation and enhanced surgical visibility, facilitating meticulous dissection in the narrow pelvis. The study validated the use of robotic platforms for complex cases and highlighted the advantages of dual-console, modular robotic surgery.
