Liver abscess, including bacterial and amoebic liver abscess, is relatively not a very serious disease, and generally can obtain a good prognosis through active and effective treatment. 1. Bacterial liver abscess: caused by bacterial infections such as Klebsiella pneumoniae, Escherichia coli and Streptococcus anaerobicus. After diagnosis, active treatment is needed, including systemic supportive therapy such as nutrition; antibiotic therapy such as ampicillin and ceftazidime; puncture and drainage of liver abscess and surgical incision and drainage. After early diagnosis and active treatment, the general prognosis is good. 2. Amebic liver abscess: a complication of intestinal amebic infection. The treatment of anti-amoebic drugs such as metronidazole and repeated puncture and drainage can get good results. Part of the complication of pyothorax, peritonitis or bacterial infection can be treated with surgical drainage. However, it should be noted that liver abscess can cause high fever, liver pain, nausea, vomiting and other symptoms, which should be taken seriously. At the same time, liver abscess can cause biliary tract infection, pyothorax, acute peritonitis, upper gastrointestinal bleeding and other serious complications, endangering the patient’s health. It is recommended to seek medical treatment in time for diagnosis and treatment.
