Management of peritoneal effusion requires treatment of the underlying cause to relieve symptoms, slow disease progression, and prevent complications.

Peritoneal effusion is an abnormal accumulation of fluid inside the abdomen. In the early stages, patients do not have obvious symptoms, so it is difficult to detect the disease. When the effusion is severe, causing the abdominal skin to stretch with symptoms of tension and discomfort, the patient goes to the doctor and conducts diagnostic tests.
