Percutaneous drainage of abscesses in the postoperative abdomen that is difficult to explore

We have evaluated our experience with computerized tomography and ultrasonography guided percutaneous drainage of extrahepatic abdominal fluid collections in a group of 22 patients. The most common goal was to avoid or delay surgery on abdomens in which reoperation would be difficult, mainly in high-risk patients. Drainage of pancreatic fluid collections or abscesses was also attempted in a small number of the patients. Percutaneous drainage was curative in 69 percent of those with nonpancreatic abscesses but in only 33 percent of those with abscesses associated with the pancreas. There were no complications attributable to the procedure or to delays in subsequent surgical drainage. Two patients died from problems not directly related to the use of percutaneous drainage. Percutaneous catheter drainage of nonpancreatic abdominal abscesses can play a useful role in patients who are carefully selected because they possess a complex abdominal anatomy distorted by previous surgery and infection or they are at high risk if surgical exploration is carried out.
