Comparisons of the clinical effectiveness between ultrasound-guided puncture drainage and open surgery in the treatment of pyogenic liver abscess / 中华普通外科杂志

ABSTRACT

Objective To compare the clinical effectiveness between puncture drainage and surgery in the treatment of pyogenic liver abscess.Methods Clinical date of 81 patients with pyogenic liver abscess were retrospectively analyzed.Patients were divided into the ultrasound-guided puncture drainage group (48 patients) and open surgical drainage group (33 patients).The demographic data,laboratory examination,efficient rate,complication rate,mortality,time for body temperature returned to normal and hospital stays were compared between the two groups.Results Klebsiella pneumoniae was positive in 45.45％ cases by blood culture,and in 62.50％ cases by pus culture.There was no statistically significant difference in the effective rate and mortality (x2 =0.91,2.05,P ＞ 0.05).For patients with puncture drainage hospital stay was (14 ± 5) days,significantly shorter than (17 ± 5) days in surgery group (t =-3.20,P ＜ 0.05).Time to normal temperature was (5.1 ± 1.6) days in puncture drainage group,which was shorter than (6.0 ± 1.1) days in open surgery group (t =-2.85,P ＜ 0.05).Postoperative complications were fewer in the puncture drainage group (6 cases) than open surgery group (10 cases) (x2=3.91,P ＜ 0.05).Conclusions Ultrasound-guided puncture drainage for liver abscess is safe,feasible,effective of low complication rate for the treatment of pyogenic liver abscess.
