 A cytoreductive surgery is a procedure performed to treat any cancer that spread to peritoneal cavity by removing a tumor and any nearby tissues to which the cancer may have spread. Pre-procedure, you may undergo routine blood tests and scans. The doctor may advise you to stop certain medications a few days before the surgery. On the day of the surgery, you are administered general anesthesia after which the surgeon makes incision to remove all visible tumors within the peritoneal cavity. The peritoneal cavity is then washed out with heated chemotherapy. This eliminates tumors that are too small to be seen. The entire procedure could take anywhere between 6 to 12 hours depending on the severity. A post-surgery, a nasogastric tube and a urinary catheter attached during the surgery will remain with you for a few days. Most patients are discharged from the hospital within a week and you may be asked to complete follow-up visits after the surgery.
