Background and aim: Repeat hepatectomy is increasingly performed for the management of recurrent colorectal liver metastases (CRLM). The aim of this study was to evaluate long-term functional liver volume (FLV) after a second hepatic procedure and to measure survival outcome.
Methods: In this retrospective cohort study, patients treated for recurrent CRLM in the years 2005–2015 at two liver centers were included. Total FLV was calculated before the first procedure and before and after the second procedure. Overall survival was calculated.
Results: Eighty-two patients were identified. The median follow-up was 53 (40–71) months from the first procedure. The median interval between first and second procedure was 13 (8–22) months. The initial FLV was 1584 (1313–1927) mL. The FLV was 1438 (1204–1896) mL after the first procedure and 1470 (1172–1699) mL after the second procedure (P<0.001). After the second procedure, a total of ten patients (12%) had a residual liver volume of less than 75% of the initial liver volume. The 5-year overall survival was 37 (26–54)% after the second procedure.
Conclusion: Small changes in FLV were found after two hepatic procedures but with considerable inter-individual variation. Patients selected for a repeated hepatic procedure for recurrent CRLM had an acceptable survival.
