Simultaneous Surgery for Synchronous Colorectal Liver Metastases

Colon cancer is one of the leading malignant diseases in the Western world, leading to significant morbidity and has significant predilection for liver metastases. Synchronous metastases account for approximately 15–25% of the newly discovered liver lesions. The only curative treatment for colon cancer liver metastases (CLM) remains surgery. Several strategies have been developed for the treatment of synchronous CLM, including simultaneous resection, two-stage liver surgery, and liver-first approach. The timing of surgery is not universally determined. Even more reports support the simultaneous resection strategy with results showing similar morbidity, length of hospital stay, and perioperative mortality comparable to staged resection. In conclusion, SCLM patients can successfully be treated with simultaneous approach or stages, both having similar perioperative and long-term outcomes. With the advance of liver surgery techniques, minor and major liver surgeries can be performed safely with low morbidity and mortality as part of either a simultaneous or a staged operative strategy
