Inter-platform Variability of Liver Elastography: Pairwise Comparisons of Four Devices.

This study was aimed at determining whether liver stiffness measurements by 2-D shear wave elastography using GE's (2D-SWE-GE) and Canon's (2D-SWE-Canon) newest apparatus and vibration-controlled transient elastography (VCTE) share the same distribution of values compared with Hologic Supersonic Imagine (2D-SWE-SSI). In participants with chronic liver disease recruited in two university centers from August 2020 to February 2021, liver stiffness was measured the same day by the same operator with 2D-SWE-SSI plus one of the following devices: 2D-SWE-GE (n = 314), 2D-SWE-Canon (n = 311), and VCTE-M probe (n = 812). VCTE-M and 2D-SWE-SSI values shared the highest correlation and concordance coefficients (0.

Non-transplantable recurrence after percutaneous thermal ablation of ≤3-cm HCC: Predictors and implications for treatment allocation.

Percutaneous thermal ablation (PTA), resection, and liver transplantation are the standard curative options for hepatocellular carcinoma (HCC). Liver transplantation yields the best long-term outcomes but is limited by graft shortage. Thus, patients with ≤3-cm HCC are primarily treated by PTA even though recurrence is frequent and may occur outside transplant criteria.

Software-based assessment of tumor margins after percutaneous thermal ablation of liver tumors: A systematic review.

Purpose: The purpose of this study was to make a systematic review of clinical studies evaluating software-based tumor margin assessment after percutaneous thermoablation (PTA) of liver tumors.

Materials And Methods: A systematic literature search was performed through Pubmed/MEDLINE, Embase and the Cochrane Library. Original studies published in English that reported on software-based assessment of ablation margins (AM) following PTA of liver tumors were selected.

Uni-, Bi- or Trifocal Hepatocellular Carcinoma in Western Patients: Recurrence and Survival after Percutaneous Thermal Ablation.

Multifocality is usually reported as a pejorative factor after percutaneous thermal ablation (PTA) of HCC but little is known in Western series. Recurrence and survival were extracted from a prospective database of all patients who underwent PTA for 3 cm HCC. From January 2015 to April 2020, we analyzed 281 patients with unifocal ( = 216), bifocal ( = 46) and trifocal ( = 16) HCC.

Hepatobiliary Scintigraphy and Glass Y Radioembolization with Personalized Dosimetry: Dynamic Changes in Treated and Nontreated Liver.

Background: The functional changes that occur over time in the liver following Y-radioembolization (RE) using personalized dosimetry (PD) remain to be investigated.

Methods: November 2016-October 2019: we retrospectively included hepatocellular carcinoma (HCC) patients treated by Y-glass RE using PD, who underwent hepatobiliary scintigraphy (HBS) at baseline and at 15 days, 1, 2, 3, and 6 months after RE.

Results: There were 16 patients with unilobar disease (100%) included, and 64 HBS were performed.

Small Steatotic HCC: A Radiological Variant Associated With Improved Outcome After Ablation.

Percutaneous thermal ablation is a validated treatment option for small hepatocellular carcinoma (HCC). Steatotic HCC can be reliably detected by magnetic resonance imaging. To determine the clinical relevance of this radiological variant, we included 235 patients (cirrhosis in 92.

Deportalization, Venous Congestion, Venous Deprivation: Serial Measurements of Volumes and Functions on Morphofunctional 99mTc-Mebrofenin SPECT-CT.

The objective was to assess the changes in regional volumes and functions under venous-impaired vascular conditions following liver preparation. Twelve patients underwent right portal vein embolization (PVE) ( = 5) or extended liver venous deprivation (eLVD, i.e.

Liver venous deprivation versus portal vein embolization before major hepatectomy: future liver remnant volumetric and functional changes.

Background: We previously showed that embolization of portal inflow and hepatic vein (HV) outflow (liver venous deprivation, LVD) promotes future liver remnant (FLR) volume (FLR-V) and function (FLR-F) gain. Here, we compared FLR-V and FLR-F changes after portal vein embolization (PVE) and LVD.

Methods: This study included all patients referred for liver preparation before major hepatectomy over 26 months.

Neck transection level and postoperative pancreatic fistula after pancreaticoduodenectomy: A retrospective cohort study of 195 patients.

Background: The aim of this study was to evaluate the impact of the level of neck transection on clinically relevant postoperative pancreatic fistula (CR-POPF) after standard pancreaticoduodenectomy (PD) with pancreaticojejunostomy.

Method: A total of 195 patients with an early postoperative CT scan were retrospectively analyzed and divided into 2 groups (CR-POPF and No CR-POPF) in order to seek potential risk factors for CR-POPF. We focused our analysis on the relationship between CR-POPF and the level of neck transection, defined by measuring the distance between the left side of the portal vein and the remnant pancreatic stump on the postoperative CT scan.

Multimodal Percutaneous Thermal Ablation of Small Hepatocellular Carcinoma: Predictive Factors of Recurrence and Survival in Western Patients.

Background: To identify the predictive factors of recurrence and survival in an unselected population of Western patients who underwent multimodal percutaneous thermal ablation (PTA) for small Hepatocellular Carcinomas (HCCs).

Methods: January 2015-June 2019: data on multimodal PTA for <3 cm HCC were extracted from a prospective database. Local tumor progression (LTP), intrahepatic distant recurrence (IDR), time-to-LTP, time-to-IDR, recurrence-free (RFS) and overall (OS) survival were evaluated.

A simple CT score to quantify pelvic and retroperitoneal hematoma associated with pelvic fractures predicts transfusion needs, pelvic hemostatic procedures, and outcome.

Background: Pelvic and retroperitoneal hematoma (PRH) in case of pelvic fracture may lead to early hemorrhagic shock. Quantifying PRH remains challenging in clinical practice. The goal of this study was to determine the statistical association between a semi-quantitative scoring system for PRH assessed with computed tomography (CT) and transfusion needs, pelvic hemostatic procedures, and outcome.

Transarterial Chemoembolization of Hepatocellular Carcinoma with Idarubicin-Loaded Tandem Drug-Eluting Embolics.

To describe the responses, toxicities and outcomes of HCC patients treated by transarterial chemoembolization (TACE) using idarubicin-loaded TANDEM beads. Seventy-two consecutive patients (mean age: 71 years (58-84 years)) with HCC were treated by TACE using idarubicin-loaded TANDEM in a first line, over a five-year period. Most patients (89%) had liver cirrhosis classified as Child-Pugh A (90%).

Percutaneous thermal ablation of hepatocellular carcinomas located in the hepatic dome using artificial carbon dioxide pneumothorax: retrospective evaluation of safety and efficacy.

Introduction: The targeting of hepatocellular carcinomas (HCC) in the hepatic dome can be challenging during percutaneous thermal ablation (PTA). The aims of this study were (1) to evaluate the safety and efficacy of PTA of HCC in the hepatic dome that cannot be visualized under US, using artificial CO2 pneumothorax and CT-guidance and (2) to compare the results with US-visible HCC located in the liver dome treated under US-guidance.

Materials: Over a 32-month period, 56 HCC located in the hepatic dome were extracted from a prospectively maintained database.

Limits of intravascular contrast extravasation on computed tomography scan to define the need for pelvic angioembolization in pelvic blunt trauma: a specific assessment on the risk of false positives.

Background: The objective was to assess the predictive performance of different intravascular contrast extravasation (ICE) characteristics for need for pelvic transarterial embolization (TAE) to determine the risk factors of false positives.

Methods: A retrospective study was performed in our trauma center between 2010 and 2015. All severe trauma patients with pelvic fracture were included.
