The pneumonia caused by inflammation can be cured, while the pneumoperitoneum caused by liver cirrhosis and cancer is difficult to cure. There are many causes of pneumoperitoneum. Some people have pneumoperitoneum due to inflammation in the abdominal cavity, which leads to obstruction of blood circulation in the body, thus causing pneumoperitoneum, and the condition of these people can be controlled after the inflammation is eliminated. However, some people develop ascites due to cirrhosis of the liver. If cirrhosis of the liver enters an advanced stage, it will cause patients to develop portal hypertension, which will affect the blood return to the abdominal vena cava, causing an increase in abdominal exudate and the formation of hepatic ascites. For ascites caused by cirrhosis, it can be treated with intravenous infusion of human albumin, but as long as the condition of cirrhosis does not improve, the ascites will easily recur. Some people develop ascites due to tumors, and tumor diseases are not only difficult to treat, but also threaten the lives of patients, so many of them cannot be cured.
