Repositioning catheters in surgically drained abscesses.

Primary percutaneous drainage of intraabdominal abscesses under local anesthesia is an accepted method of treatment, with low morbidity and mortality. This technique was extended to patients with recurrent or secondary abscesses after initial primary surgical drainage. Four patients had abscesses drained operatively but were reevaluated several weeks later for recurrent fever. Sinography demonstrated an inadequately drained abscess cavity. Under fluoroscopic control and using local anesthesia, new drains were inserted and repositioned to provide better drainage. Resolution of the abscess cavity was documented radiographically, with improvement in the patients' clinical status.
