Impact of technical innovation on surgical outcome of laparoscopic major liver resection: 10 years' experience at a large-volume center

Laparoscopic major liver resection (major LLR) remains a challenging procedure because of the technical difficulty. Several significant technical innovations have been applied in our center since 2012. They include routine application of bipolar electrocautery, initiation of temporary increase of intra-abdominal pressure during bleeding events from veins to balance the central venous pressure, and use of temporary inflow control of the Glissonean pedicle. This study evaluated the impact of these technique modifications in patients with major LLR
