To evaluate perioperative outcomes associated with robotic versus open approaches for IWATE expert-level hepatic resection.
Approach:
Patient Selection: Eligibility required age ≥18 years, Child–Pugh class A liver function, and ECOG performance status 0–1. Exclusion criteria included liver resection combined with resection of another organ (except cholecystectomy), hepatectomy with ablation or other local therapies, preoperative imaging evidence of tumor invasion of major vessels, emergency surgery, palliative procedures, and incomplete outcome information.
Key Findings:
Robotic hepatectomy is associated with lower blood loss and shorter postoperative length of stay compared to open hepatectomy (Ban et al.).
Postoperative morbidity rates were comparable between robotic and open hepatectomy in selected cohorts (Ban et al.).
Potential benefits of robotic resection may be greater for advanced or complex operations (Ban et al.).
Interpretation:
Data addressing IWATE expert-level resection specifically are sparse, with previous studies often combining different difficulty levels (Ban et al.).
Limitations:
Limited direct risk-adjusted evidence confined to the highest-difficulty subgroup (Ban et al.).
Retrospective design may introduce selection bias (Ban et al.).
Conclusion:
The study provides insights into the outcomes of robotic versus open hepatectomy for expert-level liver resections.
