Laparoscopic liver resection: lessons at the end of the second decade.

Laparoscopic liver surgery has evolved over the last two decades. Advancements in surgical technology, surgical technique, and postoperative care have aided in lifting barriers to laparoscopic liver resection (LLR). In this review, the authors highlight the modern indications, benefits, safety, and feasibility of laparoscopic liver resections. Moreover, they analyze various studies comparing laparoscopic major hepatectomies to open surgery. Morbidity and mortality rates are at an all-time low in this era of laparoscopic liver surgery. The role of laparoscopy for oncologic resections is compared with open liver resections. Attention is given to oncologic margins and survival rates. In addition, the authors examine the safety and efficacy of LLR for nontraditional laparoscopic segments and tumors abutting major hepatic vasculature. Various resection techniques are reviewed including the use of the hanging-maneuver and modern stapling devices. Finally, they examine several novel techniques for laparoscopic liver resections including the hybrid technique, as is used in laparoscopic living donor hepatectomies, the use of hand-assistance to avoid conversion to open surgery, and the use of the robotic platform to aid in complex biliary or vascular reconstructions. Current barriers to laparoscopic liver surgery will continue to fall over the next decade.
