What is Peritoneal Metastasis Surgery (CRS)?
Peritoneal Metastasis Surgery, also known as Cytoreductive Surgery (CRS), is a highly specialized oncologic procedure designed to remove cancer that has spread to the peritoneum — the lining of the abdominal cavity.
These metastases often result from cancers such as:
-
Colon and rectal cancer
-
Appendix cancer (including mucinous tumors)
-
Ovarian cancer
-
Gastric cancer
-
Peritoneal mesothelioma
The goal of CRS is to remove all visible tumor deposits from abdominal organs and peritoneal surfaces.
Why is Cytoreductive Surgery Needed?
CRS is recommended for patients who have:
-
Peritoneal metastases (peritoneal carcinomatosis)
-
Tumor spread within the abdomen without distant organ involvement
-
Pseudomyxoma Peritonei (PMP)
-
Recurrent abdominal cancers causing ascites or discomfort
-
Appendix or colon cancer with mucin-producing tumors
-
Ovarian cancer with peritoneal spread
CRS can significantly improve survival when performed at experienced centers.

How is CRS Performed?
- Performed under general anesthesia
- Duration: 4–10 hours, depending on tumor spread
- All visible tumor tissue is removed from abdominal surfaces
- Multiple organ resections may be required
- Specialized peritonectomy techniques are applied
- ICU monitoring for the first 24 hours
- Hospital stay: 7–10 days
- Early mobilization and respiratory exercises support recovery

CRS Surgery FAQ
CRS removes visible tumors; HIPEC treats microscopic disease. Both are often combined.
In selected cases, yes — especially for PMP and early peritoneal metastasis.
Evaluation includes CT, MRI, PET-CT, tumor markers, and a PCI (Peritoneal Cancer Index) assessment.
Light activity in 3–4 weeks, full recovery in 6–10 weeks.
