Laparotomy: The peritoneum is used as a semi-permeable membrane, and metabolites are removed through the exchange of the peritoneum. The advantage is that the ability to remove medium molecular substances is relatively strong, and at the same time, it does not need to go to the hospital, it can be done at home, but the patient should pay attention to the standardization of operation, to avoid abdominal infection and other conditions.
