We performed microwave coagulation therapy (MCT) of liver on 130 patients with malignant hepatic tumor. Postoperative liver abscess was detected in seven patients, and five underwent open drainage and removal of the necrotic tissues, and their conditions were assessed. Remission was achieved in four patients who underwent open drainage and removal of the necrotic tissues of the microwave coagulation area, but one patient who developed hepatic abscess associated with hepatic hemorrhage following MCT for the deep multiple metastatic foci underwent laparotomy but ultimately died of multiple organ failure with recurrence of the hepatic hemorrhage.
Large tumor size, old age, reconstruction of the biliary tract, performing MCT more than once (on the same patient), hepatic hemorrhage, and bile leakage are considered to be risk factors for post-MCT hepatic abscess.
