[Ultrasonography-guided percutaneous drainage of hepatic abscess. Results and complications].

: Interventional echography has been proposed as an effective method for the drainage of pyogenic hepatic abscesses. We present the technique and the results with this therapeutic alternative in 23 patients suffering from this serious disease. The procedure was effective in 19 patients (82.6%), being palliative in 3 cases (a carcinoma of the gallbladder, a biliary-bowel fistula and a gastric perforation). The drainage failed in 4 patients (17.4%) (in an infected hematoma were and in 3 cases due to technical problems). There were 4 complications, one of them severe (pleural empyema). We consider that percutaneous drainage guided by echography should by a first choice in the treatment of hepatic abscesses. To achieve good results and to avoid complications it is necessary to have good knowledge of the technique.
