The LIVACOR - Trial is a European wide, randomized controlled, open-label, multicenter trial. Patients with synchronous colorectal liver metastases (CRLMs) and primary colorectal tumor are considered eligible and will be randomized between minimally invasive (MI) combined or staged colorectal resection (all colectomies, including high anterior resection) and liver resection of up to three segments.

Condition Colorectal Neoplasms Malignant, Neoplasm Metastasis
Treatment Minimally invasive simultaneous resection, Minimally invasive two-stage resection

Inclusion Criteria

≥ 18 years
Diagnosed with primary CRC with resectable synchronous CRLMs (with or without neoadjuvant chemotherapy)
Elective indication for MI combined or staged colorectal resection (all colectomies, including high anterior resection) and liver resection of up to 3 segments with a maximum of 2 separate liver resections. The MI two-staged approach includes both the conventional strategy (first resection of primary colorectal tumor followed by liver resection for CRLMs) and liver-first strategy (first CRLMs resection followed by resection of colorectal primary tumor). Patients undergoing bilobar resections are eligible (if 3 or fewer segments are resected)
BMI between and including 18-35
Patients with American Society of Anesthesiologists (ASA) physical status I-III and the American College of Surgeons national surgical quality improvement project (ACS NSQIP) universal surgical risk score of ≤ 50% for serious complications
In case of neoadjuvant chemotherapy, time interval between last chemotherapy cycle and (first) surgery should be 4-6 weeks

Exclusion Criteria

Inability to give (written) informed consent
Patients requiring a planned temporarily or permanent stoma after colorectal resection (all colectomies, including high anterior resection). Patients who will receive an unplanned stoma intraoperatively, will be analysed according to their initial treatment assignment
Patients requiring multivisceral colorectal resection (all colectomies, including high anterior resection)
Indication for MI combined or staged low anterior resection, total mesorectal excision or abdominoperineal resection and liver resection of four or more segments (i.e., hemihepatectomy or more extensive resections)
Patients with peritoneal metastases
Patients with ASA physical status IV-V and ACS NSQIP surgical risk score of > 50% for serious complications
Repeat open hepatectomy
Surgical history of colorectal- or liver resection for neoplastic disease
Surgical history of major or complicated open abdominal surgery
Indication for concurrent thermal ablation
Medical history of thermal ablation of liver for malignancy
Unresectable extrahepatic metastases
Pre-operatively reconstruction of vessels/bile ducts is deemed necessary
