Abstract

Background Preoperative interventions have increased the resectability of colorectal cancer (CRC) liver metastases. This retrospective study compares outcomes after liver resection for bilobar CRC metastases between patients who underwent parenchyma-sparing hepatectomy (PSH), i.e., segmentectomies and smaller resections on both lobes, and those treated with non-PSH, i.e., hemihepatectomy plus any resection on the other lobe. Methods A cohort of 119 patients who underwent liver resection for bilobar CRC metastases were included. Perioperative course and long-term survival were compared between 59 patients who underwent PSH and 60 patients who underwent non-PSH. Statistical analyses were done using Pearson’s chi-square test, Fisher’s... (More)

Background Preoperative interventions have increased the resectability of colorectal cancer (CRC) liver metastases. This retrospective study compares outcomes after liver resection for bilobar CRC metastases between patients who underwent parenchyma-sparing hepatectomy (PSH), i.e., segmentectomies and smaller resections on both lobes, and those treated with non-PSH, i.e., hemihepatectomy plus any resection on the other lobe. Methods A cohort of 119 patients who underwent liver resection for bilobar CRC metastases were included. Perioperative course and long-term survival were compared between 59 patients who underwent PSH and 60 patients who underwent non-PSH. Statistical analyses were done using Pearson’s chi-square test, Fisher’s exact test and the Mann-Whitney U test. Overall survival analysis was performed by the Kaplan-Meier estimator and Cox regression analysis. Results The median number of liver metastases was 2 in patients treated with PSH and 3 in those treated with non-PSH (P<0.01). Postoperative mortality, severe complications and radicality did not differ significantly between groups. Median intraoperative bleeding was 250 mL for PSH and 600 mL for non-PSH (P<0.001). Median operation time and hospital stay were significantly shorter for PSH. Overall survival was comparable between groups, also after adjustment for covariates. Conclusions There were no significant differences in outcome, except for differences in bleeding, operation time and postoperative stay, favoring PSH. Furthermore, minimizing resection did not influence radicality. Hence, this study supports the use of PSH for bilobar CRC liver metastases when possible.
