“…To date, only a few cases of laparoscopic RITA of HCC have been reported [6,8,14,33,34,38] and a few cases of laparoscopic microwave coagulation therapy have been published [16,37]. In our series, 27% of 86 patients submitted to L-LUS had new malignant nodules, which required additional treatment during the same laparoscopic procedure.…”

Safety and efficacy of laparoscopic radiofrequency of hepatocellular carcinoma in patients with liver cirrhosis

et al. 2003

Background: The optimal treatment for hepatocellular carcinoma (HCC) is surgical resection. However, only a small percentage of patients are operative candidates. Percutaneous radiofrequency interstitial thermal ablation (RITA) has been shown to be efficacious in the treatment of unresectable HCC. Recent advances in laparoscopic ultrasound have greatly improved the accuracy in detecting intrahepatic HCC nodules, many of which were missed by computed tomography. Our objective was to introduce a novel operative combination of laparoscopic ultrasound with laparoscopic RITA in the treatment of HCC. Methods: Eighty-eight patients with HCC in liver cirrhosis were submitted to laparoscopic RITA under sonographic guide. Most patients were in Child's A class of liver function. Patients with large tumors (>5 cm), portal vein thrombosis, or severe liver disease (Child's C class) were excluded. Results: The laparoscopic RITA procedure was completed in 86 of 88 patients (98% feasibility rate). Laparoscopy with laparoscopic ultrasound identified 23 new malignant lesions (27%) in comparison with the results of preoperative imaging. A total of 127 lesions were treated by RITA. There was no operative mortality. Sixty-one patients had no complication (71%). After a mean follow-up of 14.3 ± 11.6 months, a complete response with a 100% necrosis was achieved in 70 of 83 patients examined (86%). During follow-up, 9 patients (11%) locally recurred at the RITA site and 38 patients (46%) had new malignant nodules. Conclusions: Laparoscopic RITA of HCC proved to be a safe and effective technique in the short term. This technique may be indicated when the percutaneous approach to the lesion is very difficult or if the patient is too ill to undergo laparotomy.

Laparoscopic liver resection for liver tumor using a microwave tissue coagulator

et al. 2011

View full text Add to dashboard Cite

Recently, the laparoscopic approach has been used more frequently for liver resection due to the rapid development of innovative laparoscopic instruments and improvements in surgical skills. To control bleeding from liver parenchyma is important in laparoscopic surgical procedures. Microwave energy is a safe and effective coagulation device to achieve good hemostasis during hepatic resection with both open and laparoscopic techniques. We describe the method of laparoscopic liver resection using flexible-type needle and spatula-type electrodes of a microwave tissue coagulator. This technique is safe and bleeding can be easily controlled.

“…In Japan, microwave coagulators, operating at 2.45 GHz, have been uniquely developed in liver surgery for hemostasis and tissue destruction for over two decades (6,7). They have also been used in interventional thermocoagulation therapy under either ultrasonographic or laparoscopic guidance (8,9). Microwave thermocoagulation therapy has already been established as one useful minimally invasive therapy for liver tumors in Japan.…”

Purpose: To utilize a microwave coagulator for MR-guided interstitial thermal therapy of liver tumors as a clinically feasible heating device. Materials and Methods:MR-guided microwave thermocoagulation therapy was carried out 34 times in 30 patients with liver tumors (eight hepatocellular carcinoma, 22 metastatic tumors) using a 0.5 T open configuration MR system.Results: Percutaneous puncture could be accomplished both accurately and safely while monitoring real-time magnetic resonance imaging (MRI). Using a notch filter, MR images could be observed without electromagnetic interference even during microwave ablation. Temperature monitoring during ablation was possible using the proton resonance frequency method. All procedures could be successfully carried out without any complications, and the therapeutic effects were deemed satisfactory. Conclusion:MR-guided microwave thermocoagulation therapy could be one promising procedure of minimally invasive treatment for liver tumors.
