目的：比较超声引导经皮穿刺置管引流术与切开置管引流术治疗肝脓肿的疗效。方法选择行超声引导经皮穿刺置管引流术肝脓肿患者50例，列为观察组，选择同期采用切开置管引流术治疗肝脓肿患者50例，列为对照组，比较两组患者治愈率、白细胞计数（WBC）、体温恢复正常时间、拔管时间、住院时间及并发症发生情况。结果观察组 WBC 计数、体温恢复正常时间、拔管时间、住院时间分别为（4．35±1．45）d、（3．68±1．68）d、（10．85±1．66）d、（13．76±2．80）d，均明显短于对照组的（7．66±2．83）d、（6．22±2．75）d、（13．05±1．95）d、（17．96±2．91）d，两组比较差异均有统计学意义（t1＝8．352，t2＝9．145，t3＝7．552，t4＝8．443，均 P ＜0．05）；观察组术后发生切口感染1例，并发症发生率为2％，对照组术后发生切口感染2例，脓胸1例，出血2例，发生率为10％，两组比较并发症发生率差异有统计学意义（χ2＝6．73，P ＜0．05）。结论超声引导经皮穿刺置管引流术创伤小、恢复快、安全性高，值得临床推广应用。%Objective To compare the efficacy of ultrasound -guided percutaneous catheter drainage and incision and drainage catheter in treatment of liver abscess.Methods 50 cases with liver abscess who had given ultrasound -guided percutaneous catheter drainage as the observation group were randomly selected and 50 cases with liver abscess who had given open catheter drainage over the same period were selected as the control group.The cure rate,white blood cell count(WBC),body temperature returned to normal,extubation time,hospitalization and the occurrence of complications of two groups were compared.Results (1)The WBC,body temperature returned to nor-mal,extubation time,hospitalization of the observation group were (4.35 ±1.45 )d,(3.68 ±1.68)d,(10.85 ± 1.66)d,(13.76 ±2.80)d,which were significantly shorter than (7.66 ±2.83)d,(6.22 ±2.75 )d,(13.05 ± 1.95)d,(17.96 ±2.91 )d of the control group.The difference between the two groups had statistically significant (t1 =8.352,t2 =9.145,t3 =7.552,t4 =8.443,all P <0.05);(2)One case of postoperative wound infection of the observation group,the complication rate was 2%,two cases of postoperative wound infection of the control group,one case of empyema,two cases of bleeding,the incidence was 10%,the difference in the incidence of complications between the two groups were statistically significant(χ2 =6.73,P <0.05).Conclusion Ultrasound -guided percu-taneous catheter drainage was trauma,quick recovery,safer,which is worthy of clinical application.
