The purpose of this study was to improvement the nonoperative methods for treatment liver abscesses. We present the results of percutaneous therapy. Puncture and external drainage of liver abscesses were performed under ultrasonic guidance (Aloka SSD-630). using tine needle aspiration (CHIBA NEEDL, I8 X 20 Cook) and Seldinger‘s technique (catheter F 5-10). We have evaluated and discussed the specific ultrasonographic features of liver abscessesat I I5 patients (from 1990 to October 1997). Percutaneous treatment has been carried out at 92 patients, of them 75 had solitary abscesses, 17-the multiple ones (2-S). Percutaneous punctures were performed in 31 patients with the abscessesless 4 sm in diameter. Percutaneous drainage were performed in 61 patients with the abscessesmore than 4 sm. The results have been excellent with 91% healing rates. Our results show that a percutaneous therapy of liver abscessesis a serious alternative to surgery due to less hospitalization time and no mortality.
