Summary
Extended left hepatectomy enables removal of complex liver tumors. While associated with increased risks, careful patient selection ensures its safe and effective application for previously unresectable lesions.
Area of Science:
- Hepatobiliary Surgery
- Surgical Oncology
- Liver Transplantation
Background:
- Extended left hepatectomy, involving resection of liver segments II, III, IV, V, and VIII, is an advanced surgical technique.
- This procedure addresses large, centrally located liver lesions that may involve the right anterior sectoral portal pedicular structures.
Purpose of the Study:
- To evaluate the safety and efficacy of extended left hepatectomy for challenging liver lesions.
- To identify predictors of outcomes in patients undergoing this extensive liver resection.
Main Methods:
- Retrospective analysis of 51 patients who underwent extended left hepatectomy between 1992 and 1998.
- Review of preoperative, intraoperative, and postoperative data, including patient demographics, lesion characteristics, and outcomes.
- Multivariate analysis to identify independent predictors of margin status and postoperative complications.
Main Results:
- The study included 51 patients (median age 58) with various liver lesions (34 metastatic, 14 primary, 3 benign).
- Postoperative morbidity was 53% and mortality was 8%, with a median hospital stay of 10 days.
- Lesion size >8 cm was the only independent predictor of positive margins; no variables predicted morbidity or mortality.
Conclusions:
- Extended left hepatectomy is a viable option for resecting complex liver lesions previously considered unresectable.
- The procedure carries increased risks but can be performed safely with careful patient selection.
- Tumor size and proximity to vascular structures are critical factors in patient selection for this aggressive technique.
