Peritoneal effusion can have many different causes. Depending on the cause of the disease, the severity and symptoms of the disease also vary.

May I ask, does the peritoneal effusion require surgery or will it be absorbed slowly?

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.

The diaphragmatic margin sign is a small triangular abnormality that obscures the normal shape of the diaphragm. It is secondary to atelectasis in the upper lobe. It is caused by traction on the pleura or the greater interlobar fissure and the subpleural ligament.
