Abstract
Between January 1988 and April 1991, a total of 79 ultrasound-directed percutaneous punctures and (or) drainage of abscesses were performed on 31 patients (15 men, 16 women; mean age 63 [31-85] years). There were 14 hepatic, 4 splenic, 4 abdominal wall and 3 pancreatic abscesses, and one each subphrenic, presacral, retrocaecal, ischiorectal, pulmonary and in the psoas. After ultrasound localization of the abscess a fine-needle puncture was performed, after which the abscess cavity was emptied as much as possible or, in abscesses larger than 5 cm in diameter, drained through a pig-tail catheter (6-8, 4 F). Several punctures were needed in 16 patients, while in 15 a percutaneous drainage over 2-8 days was necessary. Treatment was successful after 4-17 days in 25 patients. One patient died in septic shock. Operative intervention after diagnostic puncture was undertaken in 5 patients. There were no complications related to the method. In 11 patients the further course was determined by an underlying malignant disease. No recurrence has been noted (4-36 months after treatment) in 14 patients with a benign underlying disease. Percutaneous puncture and drainage of pyogenic abscesses is a technically simple method which achieves good results.
