Propensity score analysis of non-anatomical versus anatomical resection of colorectal liver metastases.

ABSTRACT:

Background

There are concerns that non-anatomical resection (NAR) worsens perioperative and oncological outcomes compared with those following anatomical resection (AR) for colorectal liver metastases (CRLM). Most previous studies have been biased by the effect of tumour size. The aim of this study was to compare oncological outcomes after NAR versus AR.

Methods

This was a retrospective study of consecutive patients who underwent CRLM resection with curative intent from 1999 to 2016. Data were retrieved from a prospectively developed database. Survival and perioperative outcomes for NAR and AR were compared using propensity score analyses.

Results

Some 358 patients were included in the study. Median follow-up was 34 (i.q.r. 16-68) months. NAR was associated wit
