Testing for mesothelioma

Peritoneoscopy

For peritoneal mesothelioma the doctor may also look inside the abdomen with a special tool called a peritoneoscope.

The peritoneoscope is put into an opening made in the abdomen. This test is usually done in the hospital under a local anesthetic.

If fluid has collected in your abdomen, your doctor may drain the fluid out of your body by putting a needle into your abdomen and using gentle suction to remove the fluid. This process is called paracentesis.
