For the peritoneal washing, your surgeon will use a saltwater solution to wash the peritoneal cavity. Once the solution, along with cells from the peritoneal cavity, is retrieved, it's sent to a laboratory to be analyzed for cancer cells in a test called peritoneal cytology..
What is the role of ascitic fluid cytology in diagnosis?
Conclusion: Definite diagnosis of ascitic fluid effusion can be done in most of the cases by doing cytology and detailed examination like physical, biochemical and microbiological examination of that fluid. However in some cases newer techniques like cytochemistry and immunohistochemistry may require for confirmation..
Peritoneal Fluid Production The amount of fluid is normally small (less than 50 mL in humans) and contains neutrophils, mononuclear cells, eosinophils, macrophages, lymphocytes, desquamated mesothelial cells, and an average of 3.0 g/mL of protein. The volume often increases during late pregnancy.
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.
Peritoneal washing cytology (PWC) is a useful indicator of ovarian surface involvement and peritoneal dissemination by ovarian tumours. It may identify subclinical peritoneal spread and thus provide valuable staging and prognostic information, particularly for non-serous ovarian tumours.
Does peritoneal cytology upstage genital tract tumors?
Mulvaneyfound that peritoneal cytology upstaged 7–75% of female genital tract tumors, depending on the primary site. The more important issue is whether those women benefit by the upstaging and additional therapy that they frequently receive as a result.

How It Works
Peritoneal washing is performed during surgery to look for cancer or remove tumors. It is performed with the patient under general anesthesiain 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.

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 therapycan also cause cells to appear cancerous even if they are not. The use of peritoneal washing for.

Results
After the procedure, the solution is analyzed for cancer cells (peritoneal cytology). If the peritoneal cytology is positive, then cancer cells are present. If it is negative, that means cancer cells have not been found.The results also typically contain more detailed information about the types of cells found. Once the lab results are in, your hea.

Risks and Contraindications
Peritoneal washing does not cause any side effects. However, it is done under general anesthesia during cancer surgery, so you should discuss your risks with your healthcare provider. These risks will vary depending on your health and the type of surgery you have. You also may haveside effects from general anesthesia. These side effects are tempora.

Summary
Peritoneal washing is performed during surgery for certain types of cancer to help determine if cancer is present or has spread to the peritoneal cavity. It is most commonly performed as part of ovarian cancer surgery but can also be done during surgeries for endometrial, prostate, and gastric cancers. During the procedure, the peritoneal cavity is.

Uses
Peritoneal washings are typically performed when healthcare providers suspect cancer may be present.It is most commonly used during ovarian cancer surgery. The results from peritoneal washing can determine the type of ovarian tumor a patient has and are part of the guidelines practitioners use when diagnosing the stage of cancer.A cancer's stage in.

What are the cytologic features of malignant tumors in peritoneal washings?
[13,15,16,23,24]Overall, the cytologic features of malignant tumors in peritoneal washings are little different from those in effusions, with the exception that large cell groups from intraperitoneal tumor can sometimes be dislodged into the washing [Figure 15]. Generally, these create minimal diagnostic difficulties. Table 3:.

Who Does It
Peritoneal washing is performed by a surgical team that typically includes oncologists and/or surgical oncologists and an anesthesiologist(a doctor trained to administer anesthesia).
Peritoneum cytology
Serous membrane that forms lining of abdominal cavity or coelom
The peritoneum is the serous membrane forming the lining of the abdominal cavity or coelom in amniotes and some invertebrates, such as annelids. It covers most of the intra-abdominal organs, and is composed of a layer of mesothelium supported by a thin layer of connective tissue. This peritoneal lining of the cavity supports many of the abdominal organs and serves as a conduit for their blood vessels, lymphatic vessels, and nerves.
