Percutaneous radiofrequency ablation for hepatocellular carcinoma developed on non-alcoholic fatty liver disease.

Background & Aims: Long-term outcomes after percutaneous radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC) in patients with non-alcoholic fatty liver disease (NAFLD) have been poorly studied. We aim to determine the outcomes after multibipolar RFA in these patients compared to other aetiologies as well as the prognostic impact of metabolic syndrome (MS).

Methods: Patients who underwent multibipolar RFA as the first treatment for HCC within Milan criteria (2008-2018) were enrolled in this multicentre retrospective cohort from four tertiary centres in France.

Primary angioplasty or stenting for hepatic artery stenosis treatment after liver transplantation.

Background: Endovascular treatment (EVT) by percutaneous transluminal angioplasty (PTA) or stent is the first-line treatment for hepatic artery stenosis (HAS) after liver transplantation, but there are no guidelines to help choose between PTA and stent.

Methods: Retrospective review of HAS EVT after liver transplantation, between 1999 and 2017. HAS was treated by PTA or stent.

Hepatic venous pressure gradient after portal vein embolization: An accurate predictor of future liver remnant hypertrophy.

Background: The impact of portal hemodynamic variations after portal vein embolization on liver regeneration remains unknown. We studied the correlation between the parameters of hepatic venous pressure measured before and after portal vein embolization and future hypertrophy of the liver remnant after portal vein embolization.

Methods: Between 2014 and 2017, we reviewed patients who were eligible for major hepatectomy and who had portal vein embolization.

No-touch multibipolar radiofrequency ablation vs. surgical resection for solitary hepatocellular carcinoma ranging from 2 to 5 cm.

Background & Aims: No-touch multibipolar radiofrequency ablation (NTM-RFA) represents a novel therapy that surpasses standard RFA for hepatocellular carcinoma (HCC), but it has not been compared to surgical resection (SR). We aimed to compare the outcomes of NTM-RFA and SR for intermediate-sized HCC.

Methods: Between 2012 and 2016, 141 patients with solitary HCC ranging from 2 to 5 cm were treated by NTM-RFA or SR at a single-center.

Phase-contrast MRI evaluation of haemodynamic changes induces by a coeliac axis stenosis in the gastroduodenal artery.

Objective: To evaluate the correlation between the gastroduodenal artery (GDA) haemodynamic changes and the degree of coeliac axis (CA) stenosis using phase-contrast MRI.

Methods: The study was institutional review board approved, and written informed consent was obtained from patients included prospectively. A two-dimensional phase-contrast MRI was performed in 23 patients scheduled for a potential complex supramesocolic surgery, in a plane perpendicular to the GDA, during inspiration and expiration.

Comparison of no-touch multi-bipolar vs. monopolar radiofrequency ablation for small HCC.

Background & Aims: The primary aim of this study was to compare the rate of global radiofrequency ablation (RFA) failure between monopolar RFA (MonoRFA) vs. no-touch multi-bipolar RFA (NTmbpRFA) for small hepatocellular carcinoma (HCC) ⩽5cm in cirrhotic patients.

Methods: A total of 362 cirrhotic patients were included retrospectively across four French centres (181 per treatment group).

Massive multinodular head and neck recurrence of parotid gland pleomorphic adenoma: a case report.

Introduction. The optimal initial management of parotid pleomorphic adenomas reduces the risk of recurrence and malignant transformation. Surgery of recurrence can be difficult in multinodular disseminated forms.

[Malignant transformation of multiple isolated hepatocellular adenomas. Therapeutic implications of immunohistochemical and radiological findings].

Malignant transformation of hepatic adenoma (HA) is now a well-documented phenomenon. Recent pathological and immunophenotypic studies have identified several subtypes with different prognoses. In many cases the HA subtype can be determined by modern radiological methods, including contrast-enhanced ultrasonography (CEUS) and magnetic resonance imaging (MRI).

Hepatocellular adenoma: evaluation with contrast-enhanced ultrasound and MRI and correlation with pathologic and phenotypic classification in 26 lesions.

Purpose. To review the contrast-enhanced ultrasonographic (CEUS) and magnetic resonance (MR) imaging findings in 25 patients with 26 hepatocellular adenomas (HCAs) and to compare imaging features with histopathologic results from resected specimen considering the new immunophenotypical classification.
