Timing of resection of synchronous colorectal liver metastasis: A systematic review and meta‐analysis

The resection of the primary colorectal tumor and liver metastases is the only potentially curative strategy. In such cases, there is no consensus on whether the resection of the primary tumor and metastases should be performed simultaneously or whether a staged approach should be performed (resection of the primary tumor and after, hepatectomy, or the “liver first” approach). The aim of this study is to evaluate the results of hepatectomy associated with colectomy in colorectal neoplasms, comparing simultaneous and staged resection.
