A 70-year-old man with a growing liver tumor had undergone subtotal gastrectomy with pancreaticoduodenectomy for gastric cancer (T4b P0 H0 N1, Stage IIIB) 30 months before admission to our hospital. Enhanced computed tomography revealed two hypervascular nodules in segments 4 and 8. After histological diagnosis of small liver metastases from gastric cancer in segment 8, the patient underwent open microwave coagulation therapy (MCT) for the tumor (diameter: 30 mm) in segment 4. MCT was performed by using 1.5-cm and 3-cm monopolar needle electrodes with 22 times of puncture under the condition of 100 W × 60 sec. Liver abscess developed at the MCT site; however, it was decreased with percutaneous drainage. The patient is alive, without tumor recurrence even after 15 years since the MCT. This successful case proves that appropriate MCT is a promising treatment for patients with gastric liver metastases.
