Peritoneal Washing: Limits and Risks

Uses

Peritoneal washing, also known as abdominopelvic washing, is a procedure used to diagnose whether certain types of cancer are present in the peritoneal cavity—the space between the membranes that line the abdomen. It is not performed on its own but during surgeries to remove tumors or see if tumors are present in the body.

Peritoneal washing is most commonly performed during ovarian cancer surgeries, but it is also used in endometrial, pancreatic, and gastric cancer surgeries. The results of this procedure help diagnose a patient with cancer, determine how far the cancer has progressed, and develop a treatment plan.

What is Peritoneal Washing?

Peritoneal washing is a process that involves flushing the peritoneal cavity with a saline solution, which is then drained and analyzed to detect the presence of cancer cells.

Limitations

Results from specimens obtained during peritoneal washing can sometimes be challenging to interpret. Certain conditions, such as endometriosis, can make cells appear cancerous even though they are benign (not cancerous). Chemotherapy or radiation therapy can also cause cells to appear cancerous even if they are not.

The use of peritoneal washing for determining the prognosis and treatment for endometrial cancer, especially in its early stages, is debated in the medical community.

How It Works

Peritoneal washing is performed during surgery to look for cancer or remove tumors. It is performed with the patient under general anesthesia in a hospital setting and before other surgical procedures. This is to make sure the sample is kept clean and away from any other tumors that might be found or removed during the surgery.

The peritoneal cavity is bathed in a sterile saline or saltwater solution during the procedure. The solution and cells from the cavity are then removed and sent to a lab to be tested. How long the procedure will take and the amount of time needed to recover depends on the type and extent of the overall surgery being done.

Conclusion

Peritoneal washing is a valuable tool in the diagnosis and treatment of certain types of cancer. While it has some limitations, it can provide valuable information about the presence and spread of cancer cells in the peritoneal cavity. Patients undergoing peritoneal washing should discuss the procedure and its potential outcomes with their healthcare provider.
