Introduction:
Patients with colorectal cancer frequently present with liver metastases requiring either concurrent colon and liver resection or staged resection for curative therapy. The goal of this study is to determine if synchronous resection increases risk of perioperative adverse outcomes such as surgical site infections (SSIs).
Methods And Procedures:
We conducted a cross-sectional retrospective analysis of the targeted hepatectomy NSQIP database from 2015 to 2019. The primary outcome was surgical site infections stratified into superficial, deep, organ space, and wound dehiscence. We performed univariate followed by a multivariate logistic regression to determine if there were higher odds of SSIs in patients undergoing hepatic resection concurrently with primary colorectal resection. Additionally, we performed stratified analyses by size of hepatic resections (partial, total left, total right, and trisegmentectomy).
Results:
Of the 7,445 patients included in the study, 431(5.8%) underwent synchronous resection and 7,014 metachronous resection. On average, synchronous resections prolonged surgery by 62 min. There was no difference in superficial and deep SSIs between the groups; however, there was a significant difference in organ space SSIs. Patients undergoing synchronous resection had 1.51 times the odds of developing an organ space SSI (OR 1.51, 95%CI 1.10, 2.17, p = 0.04) compared to patients with metachronous resection on multivariate analysis. Patients undergoing a total right hepatectomy concurrently with a colorectal resection had 2.30 times the odds of developing an organ space SSI (OR 2.30, 95%CI 1.20, 6.86, p = 0.010).
Conclusions:
Prior studies demonstrated that synchronous resections are safe in properly selected patients with no difference in long-term outcomes. Few studies have explored immediate perioperative outcomes between the two approaches. After controlling for confounders, we demonstrate that synchronous resection with major hepatic surgery increases the risk of organ space SSIs. Future studies should elucidate the precise source of organ space SSIs in order to decrease the risk of this adverse outcome.
