Summary
Repeat laparoscopic liver resection (Rep-LLR) is feasible and offers outcomes comparable to initial LLR (Ini-LLR). This study assessed the safety and efficacy of Rep-LLR, including repeat anatomical resection (Rep-AR), for recurrent liver tumors.
Area of Science:
- Hepatobiliary surgery
- Minimally invasive surgery
- Surgical oncology
Background:
- Laparoscopic liver resection (LLR) indications have expanded to include recurrent liver tumors.
- The feasibility of repeat LLR, including repeat anatomical resection (Rep-AR), requires thorough assessment.
Purpose of the Study:
- To investigate the feasibility of repeat laparoscopic liver resection (Rep-LLR).
- To compare surgical outcomes of Rep-LLR with initial LLR (Ini-LLR).
- To identify predictors of difficulty in Rep-LLR.
Main Methods:
- Retrospective review of 297 patients who underwent LLR.
- Comparison of surgical outcomes between 235 patients undergoing Ini-LLR and 62 patients undergoing Rep-LLR.
- Multivariate analysis to identify predictors of Rep-LLR difficulty.
Main Results:
- No significant differences in operation time, blood loss, conversion rate, or postoperative outcomes between Rep-LLR and Ini-LLR groups.
- Lower use of the Pringle maneuver in the Rep-LLR group.
- Initial sectionectomy and IWATE difficulty score ≥6 predicted Rep-LLR difficulty; adhesion barriers reduced Pringle maneuver failure risk.
Conclusions:
- Repeat laparoscopic liver resection (Rep-LLR) demonstrates short-term outcomes comparable to initial LLR (Ini-LLR).
- Rep-LLR is a feasible option for managing recurrent liver tumors.
