Analysis of prognostic impact factors of liver abscess with interventional treatment

Objective To analyze the prognostic factors of percutaneous catheter drainage in the treatment of liver abscess. Methods A total of 116 patients with liver abscess were treated by DSA guided percutaneous liver puncture and drainage under guidance. The average age was 59.98±16.73 years old, including 76 males and 40 females. According to past history, 49 cases of diabetes, nondiabetes in 67 cases; 48 cases of solitary abscess, 68 cases of multiple; 104 cases with complications during hospitalization, 12 cases without complication. From the puncture fluid bacterial culture results of view, Escherichia coli positive in 20 cases, 52 cases of pneumonia Cray bacteria and other pathogens in 8 cases, 36 cases of culture negative. According to the washing liquid is divided into 2 groups, A group: after placing the drainage tube, the liver abscess was washed with metronidazole injection, bacterial culture and drug sensitivity were made clear to the use of sensitive antibiotics injection to flush the pus cavity, a total of 68 cases; group B: 48 cases were washed with metronidazole after setting the tube. Results The effective rate of 116 cases of liver abscess was 100%. The statistical analysis showed that there was no significant difference in the effect of sex, or without complications on the length of hospital stay. The influence of the number of diabetes, the number of abscess and the different irrigation methods on the length of hospital stay was statistically significant. Conclusions DSA guided percutaneous liver puncture and drainage of the treatment of liver abscess is effective, Diabetes is an important factor affecting the length of hospital stay. The length of hospital stay was significantly increased in multiple liver abscess. The effect of the use of sensitive antibiotics in the liver abscess was more obvious.
