Summary
Robotic-assisted hemi-hepatectomy (RH) is safe and effective. RH offers less blood loss, and robotic-assisted left hemi-hepatectomy shows improved outcomes, though robotic-assisted right hemi-hepatectomy has longer operation times.
Area of Science:
- Minimally Invasive Surgery
- Hepatobiliary Surgery
- Surgical Robotics
Background:
- Robotic systems are common in hepatectomy.
- Effectiveness of robotic-assisted hemi-hepatectomy (RH) requires further study.
Purpose of the Study:
- To evaluate the effectiveness and feasibility of robotic-assisted hemi-hepatectomy (RH) compared to open hemi-hepatectomy (OH).
Main Methods:
- Retrospective analysis of 163 patients undergoing RH or OH by a single surgeon (Jan 2010-Aug 2023).
- Stabilized inverse probability of treatment weighting (IPTW) adjustment for comparative analysis.
Main Results:
- RH showed significantly less blood loss than OH post-IPTW adjustment.
- Robotic-assisted left hemi-hepatectomy: shorter stay, fewer complications, less blood loss.
- Robotic-assisted right hemi-hepatectomy (RRH): less blood loss, lower transfusion rates, but longer operation time.
Conclusions:
- RH is a safe and effective hemi-hepatectomy technique.
- Robotic-assisted left hemi-hepatectomy offers benefits in recovery and complications.
- RRH shows transfusion advantages but increased operative time.
