Gastrointest Endosc Clin N Am 2019 Apr 2;29(2):369-379. Epub 2019 Feb 2.

Division of Gastroenterology and Hepatology, Mayo Clinic Phoenix, Phoeniz, AZ, USA. Electronic address:

"Endoscopic ultrasound (EUS)-guided ablative therapies have advanced significantly and have led to experimental applications in locations that have been difficult to image and/or reach with percutaneous approaches, such as the caudate and left lobe of the liver. EUS-guided treatments of the liver are under development. The literature has shown that many percutaneous ablative techniques are readily adaptable for EUS. Read More

Complications from percutaneous microwave ablation of liver tumours: - A pictorial review.

Br J Radiol 2019 Mar 8:20180864. Epub 2019 Mar 8.

1 Department of Radiology, King's College Hospital , London , England.

Percutaneous microwave ablation of liver tumors is a well-established technique that has been proven to be effective in the curative and palliative treatment of small volume primary and secondary liver tumours. Microwave ablation is designed to achieve larger areas of necrosis compared to radiofrequency ablation and has a good safety profile among liver tumor treatments. Mortality is unreported and major complications are rare. Read More

Percutaneous ablation for perivascular hepatocellular carcinoma: Refining the current status based on emerging evidence and future perspectives.

World J Gastroenterol 2018 Dec;24(47):5331-5337

Department of Radiology and Center for Imaging Science, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul 135-710, South Korea.

Various therapeutic modalities including radiofrequency ablation, cryoablation, microwave ablation, and irreversible electroporation have attracted attention as energy sources for effective locoregional treatment of hepatocellular carcinoma (HCC); these are accepted non-surgical treatments that provide excellent local tumor control and favorable survival. However, in contrast to surgery, tumor location is a crucial factor in the outcomes of locoregional treatment because such treatment is mainly performed using a percutaneous approach for minimal invasiveness; accordingly, it has a limited range of ablation volume. When the index tumor is near large blood vessels, the blood flow drags thermal energy away from the targeted tissue, resulting in reduced ablation volume through a so-called "heat-sink effect".

Transthoracic radiofrequency ablation for hepatic tumor located beneath the diaphragm under one-lung ventilation: A case report.

Medicine (Baltimore) 2018 Dec;97(51):e13863

Department of Anesthesiology and Pain Medicine, College of Medicine, Kyung Hee University, Seoul, Korea.

Rationale: Radiofrequency ablation (RFA) has become the reliable, effective, and less invasive treatment for small primary or metastatic hepatic tumors. Hepatic tumors that located immediately beneath the diaphragm are difficult to treat with percutaneous RFA due to poor visualization by percutaneous ultrasonography and the close location of the heart or lung. A transthoracic approach has been proposed to be an alternative for hepatic tumors located beneath the diaphragm that are difficult to access by conventional percutaneous or laparoscopic approaches.

Département d'oncoradiothérapie, institut Claudius-Regaud, institut universitaire du cancer de Toulouse- Oncopole, 1, avenue Irène-Joliot-Curie, 31059 Toulouse cedex 9, France. Electronic address:

Patients with hepatocellular carcinoma who are on liver transplant waiting list usually require local treatment to limit any risk of tumour growth. Historically percutaneous radiofrequency ablation or transarterial chemoembolization represented the major therapeutic alternatives. Depending on the size, or the topography of the lesion these two techniques may not be feasible. Read More

1 Service de Radiologie de l'Hôpital Jean Verdier, Hôpitaux universitaires Paris-Seine-Saint-Denis, Bondy, France.

Three-dimensional virtual target fluoroscopic display is a new guidance tool that can facilitate challenging percutaneous ablation. The purpose of this study was to assess the feasibility, local efficacy, and safety of liver ablation assisted by three-dimensional virtual target fluoroscopic display. Sixty-seven hepatocellular carcinomas (mean diameter: 31 mm, range: 9-90 mm, 24 ≥ 30 mm, 16 of an infiltrative form) in 53 consecutive patients were ablated using irreversible electroporation (n = 39), multibipolar radiofrequency (n = 25), or microwave (n = 3) under a combination of ultrasound and three-dimensional virtual target fluoroscopic display guidance because the procedures were considered to be unfeasible under ultrasound alone.

A successful treatment for hepatocellular carcinoma with Osler-Rendu-Weber disease using radiofrequency ablation under laparoscopy.

Clin J Gastroenterol 2018 Dec 16;11(6):501-506. Epub 2018 Jun 16.

Division of Gastroenterology, Department of Medicine, Jichi Medical University School of Medicine, 3311-1 Yakushiji, Shimotsuke, Tochigi, 329-0498, Japan.

Hepatocellular carcinoma (HCC) can be difficult to diagnose and treat in patients with Osler-Rendu-Weber disease due to vascular malformation and regenerative nodular hyperplasia. In addition, percutaneous liver puncture should be avoided for the diagnosis and treatment as the procedure carries a high risk of bleeding. We herein report the successful treatment of HCC in a patient with Osler-Rendu-Weber disease using radiofrequency ablation (RFA) under laparoscopy. Read More

Integrating interventional oncology in the treatment of liver tumors.

Eur Surg 2018 13;50(3):117-124. Epub 2018 Apr 13.

1Department of Radiology, Medical University Innsbruck, Anichstr. 35, 6020 Innsbruck, Austria.

Background: Percutaneous ablation techniques offer a vast armamentarium for local, minimally invasive treatment of liver tumors, nowadays representing an established therapeutic option, which is integrated in treatment algorithms, especially for non-resectable liver tumors. The results of ablative treatment compare very well to surgical treatment in liver lesions, and confirm that these techniques are a valuable option for bridging for transplantation. Different techniques have been established to perform tumor ablation, and the feasibility varies according to the procedure and technical skills of the operator, depending on the size and location of the liver lesion.

Efficacy of microwave ablation versus radiofrequency ablation for the treatment of hepatocellular carcinoma in patients with chronic liver disease: a randomised controlled phase 2 trial.

Lancet Gastroenterol Hepatol 2018 05 2;3(5):317-325. Epub 2018 Mar 2.

Department of Radiology and Interventional Radiology, Lausanne University Hospital and University of Lausanne, Lausanne, Switzerland.

Background: Radiofrequency ablation is the recommended treatment for patients with hepatocellular carcinoma who have lesions smaller than 3 cm and are therefore not candidates for surgery. Microwave ablation is a more recent technique with certain theoretical advantages that have not yet been confirmed clinically. We aimed to compare the efficacy of both techniques in the treatment of hepatocellular carcinoma lesions of 4 cm or smaller. Read More
