European validation of the classification for the anticipated difficulty of liver transplantation.

Background: Appropriate risk stratification for the difficulty of liver transplantation (LT) is essential to guide the selection and acceptance of grafts and avoid morbidity and mortality.

Methods: Based on 987 LTs collected from 5 centers, perioperative outcomes were analyzed across the 3 difficulty levels. Each LT was retrospectively scored from 0 to 10.

Mesenchymal stromal cell-derived extracellular vesicles therapy openings new translational challenges in immunomodulating acute liver inflammation.

Inflammation plays a critical role in conditions such as acute liver failure, acute-on-chronic liver failure, and ischemia-reperfusion-induced liver injury. Various pathogenic pathways contribute to liver inflammation, involving inflammatory polarization of macrophages and Küpffer cells, neutrophil infiltration, dysregulation of T cell subsets, oxidative stress, and activation of hepatic stellate cells. While mesenchymal stromal cells (MSCs) have demonstrated beneficial properties, their clinical translation is limited by their cellular nature.

Comparing indications, complexity and outcomes of laparoscopic liver resection between centers with and without a liver transplant program: a French nationwide study.

Background: There are no data to evaluate the difference in populations and impact of centers with liver transplant programs in performing laparoscopic liver resection (LLR).

Methods: This was a multicenter study including patients undergoing LLR for benign and malignant tumors at 27 French centers from 1996 to 2018. The main outcomes were postoperative severe morbidity and mortality.

Flow Cytometry Assessment of Lymphocyte Populations Infiltrating Liver Tumors.

Tissue-resident and recruited immune cells are essential mediators of natural and therapy-induced immunosurveillance of liver neoplasia. This idea has been recently reinforced by the clinical approval of immune checkpoint inhibitors for the immunotherapy of hepatocellular carcinoma and cholangiocarcinoma. Such research progress relies on the in-depth characterization of the immune populations that are present in pre-neoplastic and neoplastic hepatic lesions.

Diethylnitrosamine Induction of Hepatocarcinogenesis in Mice.

Diethylnitrosamine (DEN) is a chemical hepatocarcinogenic agent that triggers a large array of oncogenic mutations after a single injection. Initiated hepatocytes subsequently undergo clonal expansion within a proliferative environment, rendering the DEN model a comprehensive carcinogen. In rodent studies, DEN finds extensive utility in experimental liver cancer research, mimicking several aspects of human hepatocellular carcinoma (HCC), including angiogenesis, metabolic reprogramming, immune exhaustion, and the ability to metastasize.

Rescue Liver Transplantation for Posthepatectomy Liver Failure: A Systematic Review and Survey of an International Experience.

Background: Rescue liver transplantation (LT) is the only life-saving option for posthepatectomy liver failure (PHLF) whenever it is deemed as irreversible and likely to be fatal. The goals were to perform a qualitative systematic review of rescue LT for PHLF and a survey among various international LT experts.

Methods: A literature search was performed from 2000 to 2022 using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and Population, Intervention, Comparison, Outcome framework, and to this, the authors' experience was added.

Patients' perceptions of the definition of a textbook outcome following liver transplantation.

Background: A textbook outcome (TO) describes the results of a successful liver transplantation (LT) in which all aspects of the LT and posttransplant courses were uneventful. We compared patient perceived experience of a TO with clinically defined TO.

Methods: This was a single-institution cohort study with retrospective chart review including patients who underwent LT from 2019 to 2021.

Value of non-coding RNAs to assess lymph node status in cervical cancer.

Cervical cancer (CC) is the fourth cancer in women and is the leading cause of cancer death in 42 countries. Lymph node metastasis is a determinant prognostic factor, as underlined in the latest FIGO classification. However, assessment of lymph node status remains difficult, despite the progress of imaging such as PET-CT and MRI.

Standardized Technique of Selective Left Liver Vascular Exclusion During Laparoscopic Liver Resection for Benign and Malignant Tumors.

Background: Tumors located close to major hepatic veins pose a technical challenge to standard laparoscopic liver resection. Hepatic outflow occlusion may reduce the risks of bleeding from hepatic vein and gas embolism. The aim of this study was to detail our standardized laparoscopic approach for a safe extrahepatic control of the common trunk of middle and left hepatic veins during laparoscopic liver resection and to assess its feasibility in patients with tumors located in both right and left lobes of the liver.

Guidelines for Perioperative Care for Liver Transplantation: Enhanced Recovery After Surgery (ERAS) Recommendations.

Background: Enhanced Recovery After Surgery (ERAS) is a multimodal, evidence-based, program of care developed to minimize the response to surgical stress, associated with reduced perioperative morbidity and hospital stay. This study presents the specific ERAS Society recommendations for liver transplantation (LT) based on the best available evidence and on expert consensus.

Methods: PubMed and ClinicalTrials.

Impact of the first Covid-19 outbreak on liver transplantation activity in France: A snapshot.

Background: The global pandemic of Coronavirus Disease 2019 (COVID-19) has potentially affected liver transplantation (LT) programs worldwide. The aim of this study was to determine whether the COVID-19 outbreak affected organ donation and LT activity in France.

Methods: Data on the number of brain-dead donor procurements and adult liver transplantations were compared between two periods (1 January- 31 May 2019 vs.

Outcomes after 3D laparoscopic and robotic liver resection for hepatocellular carcinoma: a multicenter comparative study.

Background: The recent development of 3D vision in laparoscopic and robotic surgical systems raises the question of whether these two procedures are equivalent. The aim of this study was to evaluate the surgical and long-term oncological outcomes of 3D laparoscopic (3D-LLR) and robotic liver resection (RLR) for hepatocellular carcinoma (HCC).

Methods: The data for operative time, morbidity, margins, and survival were reviewed for 3D-LLR and compared with RLR.

Surgical Glove Technique for Laparoscopic Liver Resection.

Background: Liver tumors located in segments 7 and 8 pose a technical challenge to standard laparoscopic liver resection. Intraoperative placement of a surgical glove behind the right liver after the right triangular ligament and coronary ligament are divided facilitates liver exposure during parenchymal transection and control of the bleeding at the deeper part of the parenchymal plane. The aim of this study was to describe our standardized technique in detail and to assess the feasibility of this technique in patients with different clinical backgrounds and clarify the limits of this technique.
