Summary
The Hugo™ RAS system demonstrates feasibility and safety for robotic liver resection (RLR) in minor hepatectomies. This initial clinical experience shows promising outcomes for colorectal liver metastases (CRLM) treatment.
Area of Science:
- Hepatobiliary Surgery
- Minimally Invasive Surgery
- Robotic Surgery
Background:
- Minimally invasive liver resection offers advantages over open surgery.
- New robotic systems like the Hugo™ RAS are expanding options in hepatobiliary surgery.
Purpose of the Study:
- To report the first clinical experience with robotic liver resection (RLR) using the Hugo™ RAS platform.
- To evaluate the feasibility and safety of the Hugo™ RAS system in liver resections for colorectal liver metastases (CRLM).
Main Methods:
- A prospective case series of the first 3 consecutive patients undergoing RLR for CRLM.
- Procedures performed using the Hugo™ RAS platform at a tertiary referral center.
- Collection and descriptive analysis of demographic, perioperative, and oncological data.
Main Results:
- Three patients underwent minor hepatectomies, all completed robotically without conversion.
- Median operative time was 210 minutes, with minimal blood loss (50 mL).
- No intraoperative complications, short hospital stay (median 4 days), and no postoperative complications or readmissions at 90-day follow-up. All specimens achieved R0 margins.
Conclusions:
- Robotic liver resection using the Hugo™ RAS system is feasible and safe for selected minor hepatectomies.
- The Hugo™ RAS system shows potential for improving outcomes in CRLM treatment.
- This initial experience supports further investigation of robotic approaches in liver surgery.
