Abstract
Introduction: Existing literature on the safety of combined liver and colorectal resections for synchronous colorectal liver metastases is mixed. Using a retrospective review of our institutional data, we aimed to show that combined colorectal and liver resections for synchronous metastases is both feasible and safe in a quaternary center. Methods: A retrospective review of combined resections for synchronous colorectal liver metastases at a quaternary referral center from 2015 to 2020 was completed. Clinicopathologic and perioperative data was collected. Univariate and multivariable analyses were performed to identify risk factors for major postoperative complications. Results: One hundred one patients were identified, with 35 undergoing major liver resections ( ≥ 3 segments) and 66 undergoing minor liver resections. The vast majority of patients (94%) received neoadjuvant therapy. There was no difference in postoperative major complications (Clavien–Dindo grade 3+) between major and minor liver resections (23.9% versus 12.1%, P = 0.16). On univariate analysis, Albumin–Bilirubin (ALBI) score >1 (P < 0.05) was predictive of major complication. However, on multivariable regression analysis, no factor was associated with significantly increased odds of major complication. Conclusions: This work demonstrates that with thoughtful patient selection, combined resection for synchronous colorectal liver metastases can be safely performed at a quaternary referral center. © 2023 Elsevier Inc.
