Background And Objectives:
Previous reports showed an increased risk of infectious complications when liver radiofrequency ablation (RFA) is performed simultaneously to colorectal resection. The aim of this study was to compare early and long-term outcomes of simultaneous versus staged strategy.
Methods:
Data from colorectal cancer liver metastases consecutively treated by surgery of the primary tumor with an associated liver RFA procedure between January 1, 2010 and January 31, 2020. Patients were divided into two groups: RFA performed during colorectal surgery (simultaneous) or in a different moment (staged). Patients were manually matched (1:1) to minimize influence of known covariates.
Results:
Seventy-two patients were included. After matching, there was no difference between the two groups in morbidity or mortality. Hospital stay was 2 days shorter in the simultaneous group.
Conclusions:
Early or long-term outcomes were identical between the two strategies. The simultaneous strategy was associated with a shorter duration of hospitalization although not significant. Simultaneous colorectal resection and liver RFA is safe and must be included in surgeons' armamentarium.
