Infectious complications of hepatic cryosurgery.

Hepatic cryosurgery is a novel procedure for patients with metastatic liver disease. To date, no reviews of the infectious complications of this procedure have been published. One hundred and fifty patients underwent 158 hepatic cryosurgical procedures at Allegheny General Hospital (Pittsburgh) from November 1987 through July 1995. Gastrointestinal malignancies accounted for 93% of the underlying diagnoses. The following 12 infections were directly related to the cryosurgical procedure: hepatic abscess (six), intraperitoneal abscess (three), ascending cholangitis (two), and an intrahepatic device (Infusaid; Strato/Infusoid, Norwood, MA) infection (one). Enterococcus was the most commonly isolated organism. Seven of the 12 infections were polymicrobial. The patients who developed infections had longer hospital stays (26 days vs. 13 days) and had more days of fever (6.5 days vs. 2.3 days). than those who did not develop infections. If perioperative manipulation of the biliary tree is avoided, the infection rate in patients who undergo hepatic cryosurgery may be decreased even further. Overall, cryoablation of the liver is not related to an increased risk of infection.
