About

Laparoscopic liver resection (LLR) has gained acceptance as an effective treatment for colorectal liver metastases (CRLM) in selected patients, providing similar oncologic outcomes compared to open liver resection (OLR). A single-center retrospective analysis of a prospectively maintained database was performed. The primary aim of this study was to determine prognostic factors for the survival outcomes associated with LLR for CRLM.

Full description

LLR was defined as pure LLR, including conversions to OLR. In case of missing data, additional details were retrieved from the individual patient file. Data on patient demographics, timing of diagnosis, neoadjuvant chemotherapy (NAC), tumor characteristics (both primary tumor and CRLM), histopathology, molecular characteristics, operative technique (including classification into anatomically major/technically major/minor LR), intra- and postoperative course, adjuvant chemotherapy (AC) as well as oncological outcomes (OS and DFS) were gathered and analyzed. Postoperative complications were graded according to the Clavien-Dindo classification. Complications were classified as major in case of Clavien-Dindo ≥ 3A.
