Laparoscopic surgery for large left lateral liver tumors: safety and oncologic outcomes.

Background: Although laparoscopic hepatectomy has been proven to be safe and reliable, the influence of tumor size on the feasibility of laparoscopic left lateral segmentectomy (LLLS) is unclear. We retrospectively reviewed our surgical results focusing on hepatic tumor located in the left lateral segment.

Methods: From January 2003 to June 2016, patients who underwent left lateral segmentectomy were retrospectively reviewed, and data were collected on patient characteristics, peri-operative outcomes, and pathologic results.
