Abstract
Objective
To present surgical and oncological outcomes using a prospective and randomized trial (LapOpHuva, NCT02727179) comparing minimally invasive liver resection (LLR) versus open liver resection (OLR) in patients with colorectal liver metastases (CRLM).
Methods
Between February 2005 and March 2016, 204 selected patients with CRLM were randomized and 193 were included: LLR (n = 96) and OLR (n = 97). The primary endpoint was to compare postoperative morbidity. Other secondary endpoints were oncological outcomes, use of the Pringle maneuver, surgical time, blood losses, transfusions, hospital stay, mortality and OS, and disease-free survival (DFS) at 3, 5, and 7 years.
Results
LLR presented with lower global morbidity (11.5% vs. 23.7%, p = 0.025) but with similar severe complications. Long-term survival outcomes were similar in both groups. The cumulative 1-, 3-, 5-, 7-year OS for LLR and OLR were 92.5%, 71.5%, 49.3%, 35.6% versus 93.6%, 69.7%, 47.4%, 35.5%, respectively (log-rank = 0.047, p = 0.82). DFS for LLR and OLR was 72.7%, 33.5%, 22.7%, and 20.8% versus 61.6%, 27.2%, 23.9%, and 17.9%, respectively (log-rank = 1.427, p = 0.23). LLR involved more use of the Pringle maneuver (15.5% vs. 30.2%, p = 0.025) and a shorter hospital stay (4 vs. 6 days, p < 0.001). There were no differences regarding surgical time, blood losses, transfusion, and mortality.
Conclusions
In selected patients with CRLM, LLR presents similar oncological outcomes with the advantages of the short-term results associated with LLR.
