Abstract: Objective To analyze the advantages and precautions of interventional drainage in the treatment of liver abscess. Methods From September 2015 to September 2019, 49 cases of liver abscess were treated by percutaneous puncture and catheterization in the ultrasound department of our hospital. The purulent cavity was treated by puncture and catheterization drainage, concurrent purulent cavity washing, drug injection and anti infection treatment according to drug sensitivity test. Results In this study, 49 patients were successfully punctured. The percentage of leukocytes and neutrophils decreased significantly(P<0. 05). The diameter of abscess was significantly smaller than that before operation( P< 0. 05). The body temperature of 25 patients returned to normal within 3 days, 16 patients returned to normal within 3~ 7 days, and 8 patients returned to normal after 7 days. All the patients could tolerate the treatment of catheterization, the drainage time was 3~ 28 days, average 13. 5 days, no complications such as bile leakage, infection and pneumothorax occurred during and after operation, and there was no recurrence. Conclusion Ultrasound-guided percutaneous drainage of liver abscess has gradually replaced the treatment of high-dose drugs or surgery, and the clinical effect is reliable, less complications, which has obvious advantages in clinical treatment of liver abscess.
