Background
Many centers consider hepatocellular carcinoma (HCC) located in segments 7 or 8 to be unsuitable for laparoscopic liver resection (LLR). We evaluated the safety of LLR of HCC in segments 7 or 8 following the introduction of new laparoscopic techniques.
Methods
This retrospective study included 104 patients who underwent LLR (n = 46) or open liver resection (OLR) (n = 58) for HCC located in segments 7 or 8 between October 2004 and June 2015. The LLR group was subdivided into two subgroups according to whether LLR was performed before (Lap1; n = 29) or after (Lap2; n = 17) the introduction of the Pringle maneuver, intercostal trocars, and semi-lateral patient positioning.
Results
Non-anatomical resection was more frequent (63.0 vs. 29.3%; P < 0.001) and tumor size was smaller (2.8 vs. 4.7 cm; P < 0.001) in the LLR group than in the OLR group. Blood transfusion (P = 0.526), operation time (P = 0.267), postoperative complications (P = 0.051), and resection margin (P = 0.705) were similar in both groups. LLR was associated with less blood loss (550 vs. 700 ml, P = 0.030) and shorter hospital stay (8 vs. 10 days; P = 0.001). The 3-year overall (90.2 vs. 81.2%, P = 0.096) and disease-free survival (15.1 vs. 12.1%; P = 0.857) rates were similar in both groups. The Lap2 group has less blood loss (230 vs. 500 ml; P = 0.005) and shorter hospital stay (7 vs. 9 days; P = 0.038) compared with the Lap1 group.
Conclusion
LLR can be safely performed for HCC located in segments 7 or 8 with recent improvements in surgical techniques and accumulated experience.
