The feasibility and efficacy of pure laparoscopic repeat hepatectomy

Abstract

Background

Repeat hepatectomy is often required for hepatocellular carcinoma and metastatic tumors. However, this procedure is technically challenging, so laparoscopic repeat hepatectomy (LRH) has not been widely adopted. The aim of this study was to evaluate the feasibility and efficacy of LRH compared with open repeat hepatectomy (ORH) and laparoscopic primary hepatectomy (LPH).

Methods

We introduced laparoscopic hepatectomy at our institution in April 2014. We performed 127 LPH (LPH group) and 33 LRH procedures (LRH group) from April 2014 to April 2017; 37 patients underwent ORH from January 2010 to April 2017 (ORH group). This study retrospectively compared the patient characteristics and short-term outcomes of the LRH and ORH groups as well as the LRH and LPH groups.

Results

There were no conversions to open surgery in the LRH group. In comparing the LRH and ORH groups, there were no significant differences in patient characteristics except for the type of approach to the previous hepatectomy (p = 0.004) and indocyanine green retention rate at 15 min (median 12.5 vs. 8.75%, p = 0.026). The LRH group had less blood loss (median 30 mL vs. 652 mL; p < 0.001), less intraoperative transfusion (6.1 vs. 32.4%; p = 0.006), and shorter postoperative hospital stays (median 6.5 days vs. 9.0 days; p < 0.001). There were no differences with regard to operation time, severe postoperative complications, and mortality. In comparing the LRH and LPH groups, there was a significant difference only in past history of abdominal surgery (100 vs. 61.4%; p < 0.001). In the short-term outcomes, the postoperative hospital stay was significantly shorter in the LRH group (median 6.5 days vs. 7 days; p = 0.033), and the other results were comparable between the two groups.

Conclusions

LRH is feasible and useful for repeat hepatectomy, achieving good short-term outcomes.
