Using the win ratio to compare laparoscopic versus open liver resection for colorectal cancer liver metastases.

ABSTRACT:

Background

We sought to assess the overall benefit of laparoscopic versus open hepatectomy for treatment of colorectal liver metastases (CRLMs) using the win ratio, a novel methodological approach.

Methods

CRLM patients undergoing curative-intent resection in 2001-2018 were identified from an international multi-institutional database. Patients were paired and matched based on age, number and size of lesions, lymph node status and receipt of preoperative chemotherapy. The win ratio was calculated based on margin status, severity of postoperative complications, 90-day mortality, time to recurrence, and time to death.

Results

Among 962 patients, the majority underwent open hepatectomy (n=832, 86.5%), while a minority underwent laparoscopic hepatectomy (n=130, 13.5%). Am
