Radiologic treatment of abdominal abscesses with fistulous communications.

Although percutaneous radiologic drainage of abdominal abscesses is now a well-established, standard procedure, several factors may limit its success. These limitations include the absence of a safe anatomic access route, presence of fistulous communications, and association with severe inflammation of organs such as the bowel or the pancreas. This review addresses advances and persisting limitations in the percutaneous management of complex abdominal abscesses.
