Microwave surgical technique was performed upon 23 hepatic surgeries and 3 splenic surgeries. The excellent hemostatic effect on these organs' parenchymatous bleeding was confirmed. However, thermal injury to the large cutting blood vessels could make them became fragile and caused bleedingbecause of the difficulty of the suturing the broken recoiled vessels. In the case of the possible thermal damage to the important vessels which should be reserved, the MICROTAZE could only be used as a supplement to the traditional procedures for minimizing the parenchymatous bleeding.
The causes of the biliary leakage and hepatoenterostomic leakage is discussed. Means of prevention of these complications is proposed. A possibility of increase the resection rate and prolong the survival time of the malignant liver tumor by using the microwave surgery is also discussed.
