Recently, microwave coagulation therapy (MCT) is performed as minimal invasive treatment for liver tumor, and many studies concerning MCT have been reported. However, the clinical study focusing on the relationship between the accurate amount of microwave irradiation and surgical stress after MCT has not been reported. In this report, we studied the relation between the amount of microwave irradiation and the postoperative results in 30 cases who had been received laparotomic MCT. The amount of irradiation was correlated with the volume of necrosis and postoperative transaminase and LDH concentration. Abscess formation was observed in two cases who had been received high amount of irradiation. However, the amount of irradiation did not correlate to the postoperative hospitalization, the average of which is 21.0 ± 1.0 days in cases which received irradiation less than 160.0 × 103 J. The amount of irradiation would be the useful factor for estimating necrotic volume and surgical stress. Although a lot of irradiation might complicate abscess, it was suggested that MCT was safely executed in appropriate and enough amount of irradiation.
