Abstract

Background: The efficacy and safety of laparoscopic liver resections for liver tumors that are larger than 10 cm remain unclear. We developed a safe laparoscopic right hemihepatectomy for giant liver tumors using an anterior approach.

Methods: Eighty patients who underwent laparoscopic hemihepatectomy between January 2011 and December 2021 were divided into a nongiant tumor group (n = 65) and a giant tumor group (n = 15) for comparison.

Results: The median operating time, amount of blood loss, and length of postoperative hospital stay did not differ significantly between the nongiant and giant tumor groups. The sizes of the tumors and weights of the resected liver were significantly larger in the giant tumor group. A comparison between a nongiant group (n = 23) and a giant group (n = 12) treated with laparoscopic right hemihepatectomy showed similar results.

Conclusions: Laparoscopic hemihepatectomy, especially that performed on the right side, for giant tumors larger than 10 cm can be performed safely. Surgical techniques for giant liver tumors have been standardized, and their application is expected to spread widely in the future.

Keywords: anterior approach; giant liver tumor; laparoscopic hepatectomy.
