Liver abscess is a common clinical condition of suppurative lesions in the liver caused by a variety of microorganisms. Common liver abscesses include bacterial liver abscess and amoebic liver abscess. 1. Bacterial liver abscess: Liver abscess caused by bacterial invasion of the liver, mostly secondary to systemic bacterial infection, especially intra-abdominal infection when the resistance of patients is weak. Patients with underlying diseases, especially diabetic patients, are the high incidence group. The causative organisms are mostly Klebsiella pneumoniae and Escherichia coli, which can be single or multiple. Typical symptoms are chills, high fever, hepatic pain and hepatomegaly. The main treatment modalities include systemic supportive therapy, antibiotic therapy, percutaneous hepatic puncture abscess drainage, etc., and surgical treatment. 2. Amebic liver abscess: amebic liver abscess is a complication of intestinal amebic infection, the vast majority of single-occurrence, non-surgical treatment is the first choice of treatment, based on anti-amoebic drugs (metronidazole, chloroquine, emetine), as well as repeated puncture and suction of pus and supportive therapy, if necessary, percutaneous hepatic perforation and drainage, and surgical incision and drainage can also be used. When the diagnosis of liver abscess is confirmed, the cause of the disease should be clarified and standardized treatment should be carried out under the guidance of doctors.
