Cancer that has spread to the lining of the abdomen (peritoneum) often started in a nearby organ — the appendix, stomach, colon, rectum, ovaries or fallopian tubes. Mesothelioma and some rare sarcomas can also spread to this lining. The same lining covers the outside of many organs in the abdomen.
In CRS, the surgeon removes the parts of the lining where they can see cancer. Often, they also need to remove parts of organs that also have cancer.
Usually, this is open surgery, meaning it is done through one large incision (cut). Sometimes, we do minimally invasive laparoscopic surgery or robot-assisted surgery .
Your surgery team will talk with you about the details of your operation, including what will happen during surgery and what to expect after.
