Radiofrequency ablation (RFA) has been widely used as a therapeutic method for hepatocellular carcinoma. RFA has been also used for metastatic liver cancer to reduce tumor mass. Here, we describe the result of RFA therapy for metastatic liver cancer in our institution. As a result, RFA is feasible in the majority of the metastatic liver cancer cases who cannot be treated by surgical resection. In the near future, RFA may be one of the important options for the treatment of metastatic liver cancer in the near future.

Recently we performed partial splenectomy and distal pancreatectomy using a new microwavescalpel (blade type electrode). A new microwave scalpel has merit of this high hemostaticperformance and cutting performance. In the 3 cases in which one was iatrogenic intraoperativesplenic injury and two were purpcse of preserving partial splenic function treated by this partialsplenectomy and in the 9 cases or gastric carcinoma teated by this distal pancreatectomy, theseoperations was accomplished safely and postoperative complication was free. These results suggestthat this apparatus, a new microwave scalpel, may well be recommended as a medical electronicsin the splenic and pancreatic surgery.

We started microwave ablation therapy of liver tumors under MR image guidance with an open configuration MR scanner. The combination of these two was quite feasible. At the beginning, preparations of MR compatible electrodes and a noise-eliminating filter were required. After the measurements against the noise, microwave irradiation did not disturb MR images and temperature changes could be monitored using MR temperature maps, which were useful for the real-time evaluation of therapeutic effects. In addition, MR temperature maps could be used to investigate the condition of microwave ablation with newly developed instruments and applications. The encounter of microwave ablation with MR imaging made a breakthrough in the image-guided minimally invasive therapy. Further developments of new technologies for therapeutic procedures are expected from this combination.

Microwave Ablation is one of the useful treatments of hepatic tumor. It has been used as an interventional device for thermoablation therapy under ultrasonographic or laparoscopic guidance. We have done clinical studies of MR-guided microwave ablation therapy of hepatic tumors since January 2000. From January through September 2000, 18 patients with liver tumors were hospitalized in the 1st Department of Surgery at Shiga University of Medical Science. There were 13 cases of metastatic hepatic tumor. All of which had previously had primary surgery. The other 5 cases were primary hepatic cancer. All patients were selected because percutaneous ethanol injection therapy (PEIT) or transcathetal arterial embolization (TAE) was ineffective, and surgical resection could not be done because of hepatic dysfunction.We had already performed MR-guided microwave ablation therapy to hepatic tumors located in every segment of the liver. However, percutaneous puncture of the tumors in the subphrenic area was not easy with the abdominal approach. In these cases, a combination of thoracoscopic and MR-guidance has been beneficial. MR compatible endoscope made us easily to puncture hepatic tumors located in every segment of the liver. MR-guided microwave ablation therapy is a feasible treatment for hepatic tumors.

Treatment results for HCC were the barrel severely one, 30 years ago. At that time, the liver resection was not safe maneuver yet, though there was no effective treatment method except the liver resection. Afterwards, the liver resection has rapidly evolved to the safe cure by the establishment of hemostasis such as microwave coagulation during resection and the development of the operation equipment. <br>Hepatic resection and other treatment for HCC have showed remarkable progress in these 2 decades. This progress brought dramatic improvement of curability for HCC. <br>In addition, advancement of diagnostic imaging, development of tumor maker of HCC resulting in definition of high risk group of HCC, led to the further improvement of treatment result of HCC.

We performed partial nephrectomy using a microwave tissue coagulator in 4 cases of renal cell carcinoma less than 20 millimeters in diameter. All cases were asymptomatic and the tumor was found incidentally. Tumors were resected using the microwave tissue coagulator at the power of 65W, 30 seconds for coagulation, followed by 15-25 seconds of dissociation. Mean blood loss was 73.3 mL (range : 10-140 mL), and mean operation time was 140 minutes (range : 131-157 min.). The indication in our hospital for partial nephrectomy using the microwave tissue coagulator is solitary tumors of less than 30 millimeters in diameter. We demonstrate the advantages of the non-ischemic procedure especially in intraoperative blood loss and operative time compared with five cases of conventional partial nephrectomy.
