Summary
The Saroa Surgical System shows feasibility for robotic liver resection in select patients, offering practical benefits like force feedback. However, limitations in working range and instrument options exist.
Area of Science:
- Minimally Invasive Surgery
- Surgical Robotics
- Hepatobiliary Surgery
Background:
- The Saroa Surgical System is a novel robotic platform featuring force feedback, a compact design, and cost-effectiveness.
- Initial clinical experience with robotic liver resection using this system is reported.
Purpose of the Study:
- To evaluate the feasibility and safety of robotic liver resection using the Saroa Surgical System.
- To identify practical advantages and technical challenges during early implementation.
Main Methods:
- Retrospective case series of eight patients undergoing Saroa-assisted robotic liver resection.
- Inclusion of patients with superficial liver lesions not requiring anatomical resection.
- Descriptive analysis of clinical characteristics and short-term perioperative outcomes.
Main Results:
- Eight partial hepatectomies were performed for various liver pathologies, including hepatocellular carcinoma and metastatic tumors.
- Median operative time was 267 minutes, with a median blood loss of 17.5 mL.
- One case of postoperative bile leakage (Clavien-Dindo grade IIIa) occurred; three patients required smooth conversion to laparoscopy.
Conclusions:
- Robotic liver resection with the Saroa Surgical System is feasible in selected patients.
- The system's design, force feedback, and laparoscopic compatibility offer potential advantages.
- Limitations include restricted working range, limited instrument variety, and lower grasping force.
