The role of percutaneous drainage of pancreatic abscesses.

Pancreatic abscess remains the most lethal form of intra-abdominal abscess despite a wide variety of operative approaches that have been advocated for its control. Mortality is frequent, and recurrent abscesses after operative drainage are common. Death often results from ongoing uncontrolled sepsis. The role of percutaneous drainage (PCD) of pancreatic abscesses is controversial. Recent experience with five patients who had pancreatic abscess and in whom a combination of operative drainage and PCD proved instrumental in survival leads the authors to recommend the consideration of both forms of drainage dependent upon the circumstances. Specifically, indications for PCD may include the following: use as a temporizing measure prior to celiotomy in a critically ill patient; use in postoperative patients who have recurrent abscesses and in whom the presence of dense inflammation precludes safe evacuation of pus; and use in the patient who has known portal hypertension and in whom massive bleeding is likely to result from celiotomy and abscess drainage.
