Peritoneal washing

Peritoneal washing is a medical procedure used primarily in the staging of gynecological cancers, such as ovarian cancer, and to a lesser extent, in gastrointestinal cancers. It involves the introduction of a saline solution into the peritoneal cavity, which is then aspirated for examination of its contents under a microscope.

Procedure

The procedure is typically performed during a laparotomy or laparoscopy. A saline solution is introduced into the peritoneal cavity, and then aspirated. The aspirated fluid is sent to a pathology laboratory for cytological examination. The presence of malignant cells in the fluid is indicative of peritoneal spread of the cancer, which can affect the staging and treatment of the disease.

Indications

Peritoneal washing is primarily used in the staging of gynecological cancers, such as ovarian cancer. It can also be used in the staging of gastrointestinal cancers, although this is less common. The procedure can help to identify the presence of malignant cells in the peritoneal cavity, which can indicate peritoneal spread of the cancer.

Risks and complications

As with any medical procedure, peritoneal washing carries some risks. These can include infection, bleeding, and damage to surrounding organs. However, these risks are generally low.
