Percutaneous drainage of abdominal abscesses.

Abdominal abscesses carry high morbidity and mortality unless properly drained. In recent years, percutaneous drainage has become an accepted alternative to surgery. A brief overview of diagnostic principles, selection of patients, percutaneous drainage catheters and technique, contraindications, and post-drainage follow-up is presented. In experienced hands, more than 80% of abdominal abscesses can be drained successfully by this method and with lower rates of morbidity, mortality, and complications than by surgery.
