Laparoscopic isolated liver segmentectomy 8 for malignant tumors: techniques and comparison of surgical results with the open approach using a propensity score-matched study.

Laparoscopic ILSeg8 using the extrahepatic Glissonian approach and hepatic vein root at first parenchymal dissection was feasible, safe, and oncologically acceptable. In ILSeg8 for malignancy, the laparoscopic approach potentially confers short-term advantages over the open approach with comparable long-term outcomes in select patients.
