There is an accumulation of fluid in the abdomen, also known as an accumulation of fluid in the abdominal cavity. In the early stage, it may manifest as enlargement of the liver area, loss of appetite, nausea, vomiting or swelling and pain in the liver area. In the late stage, it can manifest as splenomegaly, hypersplenism and varices in the abdominal wall, spider nevus, wasting, and in severe cases, it can lead to upper gastrointestinal hemorrhage and coma. It may also lead to pleural effusion and symptoms such as dyspnea and hemoptysis. Causes of pneumoperitoneum include hypoproteinemia, cirrhosis of the liver, and kidney disease. Further CT of the upper abdomen, ultrasound of the liver, gallbladder, spleen and pancreas, and liver and kidney function tests are needed to clarify the specific causes and then treat the cause.
