Comparison of the Resection Site Order in Simultaneous Approach of Colorectal Liver Metastasis

Colorectal cancer frequently presents with liver metastases, and complete removal of both primary and liver tumors can significantly improve survival. Simultaneous resection (SA) of the colon and liver is increasingly used and is considered safe when minor liver resections are performed, offering advantages such as shorter hospitalization, fewer complications, and faster chemotherapy initiation. However, the best sequence of resection, liver-first or colon-first, remains uncertain, as each has potential benefits and drawbacks, particularly regarding anastomotic healing. Minimally invasive approaches to SA show similar outcomes to open surgery, though limited data suggest that resection order may affect blood loss.
