The liver is the organ where colon cancer most frequently metastasizes. Sometimes, we can see these two cancers at the same time. We call this condition synchronous tumors. With the latest developments in medicine, we prefer to simultaneously remove cancerous tissues from both the large intestine and the liver in patients whom we predict tolerate both surgeries.
The reason for this is to prevent the patient from undergoing two different surgeries and receiving two separate anesthesia and to prevent the progression of the tumor during the loss of time between the two operations.
One of the methods to be applied in simultaneous surgery is open surgery, and another method is the removal of the large intestine with a minimally invasive method (laparoscopic or robotic) and removing the liver with open surgery. However, in suitable patients, minimally invasive surgery can remove the tumor in both the liver and the large intestine.
