Staged resection: Patients randomized to staged resection will be operated according to the decision made by the tumor board meeting (liver or colorectal cancer first, based on tumor burden and symptoms), but both resections have to be done within a time period of 4-12 weeks.
Simultaneous resection: In cases with simultaneous surgery, the liver resection is performed prior to colon resection in order to keep a low central venous pressure during the first part of the surgical procedure and to avoid congestion of the anastomosis line owing to possible Pringle manoeuvre.
Study summary
The SYLMET Trial is a randomized trial to compare simultaneous and two-staged resection of primary colorectal and synchronous liver metastases. This is an investigator-initiated, multicentre, randomized controlled trial to assess complications (primary endpoint), survival, cost-effectiveness, and quality of life (secondary endpoints).This trial will include patients with resectable primary tumour in the colon or upper rectum with less than five liver metastases that is possible to treat with surgical resection and/or ablation (RFA/MWA) at time of evaluation.

Primary outcome measure(s)
Comprehensive Complication Index, CCI — 90 days The CCI is calculated as the sum of all complications that are weighted for their severity (multiplication of the median reference values from patients and physicians). The final formula yields a continuous scale to rank the severity of any combination of complications from 0 to 100 in a single patient.
