Core Tip
Core Tip: This study introduces a novel laparoscopic liver resection technique utilizing the ventral avascular area of the inferior vena cava. By addressing the short hepatic veins after parenchymal transection, the technique reduces liver mobilization, tumor compression, and bleeding. Compared to conventional laparoscopic liver resection, this approach significantly decreases operative time, intraoperative blood loss, and hospital stay, while enabling safer resection of larger tumors. The method provides a valuable advancement in complex liver tumor surgeries, particularly for tumors near the inferior vena cava and third hepatic hilum.
