Endovascular Management of Thrombosed Cavoportal Anastomosis After Liver Transplantation Using Catheter Directed Thrombolysis and Stent Placement: A Case Report.

Cavoportal hemitransposition (CPHT) is a rarely performed treatment technique in liver transplantation in cases of extensive splanchnic thrombosis, in which the inferior vena cava of the recipient is used to perfuse the portal vein of the allograft. A case of a 65-year-old liver transplantation patient with an acutely thrombosed cavoportal anastomosis is presented. After unsuccessful medical treatment, recanalization was obtained with transfemoral catheter directed thrombolysis, angioplasty and stent placement.

Single-session endoscopic ultrasound-directed transgastric endoscopic retrograde cholangiopancreatography with a dedicated over-the-scope fixation device: Feasibility study (with video).

Objectives: Endoscopic ultrasound-directed transgastric endoscopic retrograde cholangiopancreatography (ERCP; EDGE) is proposed as a less invasive alternative to laparoscopy-assisted ERCP. However, postponing ERCP for 1-2 weeks to reduce the risk of lumen-apposing metal stent (LAMS) migration may not be practical in urgent cases such as cholangitis, leading to increased procedural burden. This study aimed to assess the feasibility and safety of a single-session EDGE utilizing a dedicated over-the-scope fixation device.

Endoscopic ultrasound-guided pancreatic duct drainage: a comprehensive state of the art review.

Introduction: Endoscopic retrograde pancreatography (ERP) has traditionally been the standard modality for pancreatic endotherapy. However, in certain situations, failure of retrograde ductal access may warrant an alternative modality of drainage. This can occur in various settings like difficult and/or surgically altered anatomy or duodenal obstruction.

Distinct immunometabolic signatures in circulating immune cells define disease outcome in acute-on-chronic liver failure.

Background And Aims: Acute-on-chronic liver failure (ACLF) is a complication of cirrhosis characterized by multiple organ failure and high short-term mortality. The pathophysiology of ACLF involves elevated systemic inflammation leading to organ failure, along with immune dysfunction that heightens susceptibility to bacterial infections. However, it is unclear how these aspects are associated with recovery and nonrecovery in ACLF.

Tacrolimus Drug Exposure Level and Smoking Are Modifiable Risk Factors for Early Malignancy After Liver Transplantation for Alcohol-Related Liver Disease.

malignancy (DNM) is the primary cause of mortality after liver transplantation (LT) for alcohol-related liver disease (ALD). However, data on risk factors for DNM development after LT are limited, specifically in patients with ALD. Therefore, we retrospectively analyzed all patients transplanted for ALD at our center before October 2016.

Comparison of the single-cell and single-nucleus hepatic myeloid landscape within decompensated cirrhosis patients.

Background And Aims: A complete understanding of disease pathophysiology in advanced liver disease is hampered by the challenges posed by clinical specimen collection. Notably, in these patients, a transjugular liver biopsy (TJB) is the only safe way to obtain liver tissue. However, it remains unclear whether successful sequencing of this extremely small and fragile tissue can be achieved for downstream characterization of the hepatic landscape.

Histological characteristics in patients admitted to the hospital with alcoholic hepatitis complicated by acute-on-chronic liver failure.

Objectives: Alcoholic hepatitis (AH) is a frequent precipitating event for the development of acute-on-chronic liver failure (ACLF), a syndrome characterised by organ failures due to immune dysfunction. The histological features of this complication are not well characterized. We investigated whether ACLF has specific histological characteristics.

Adipose tissue macrophage dysfunction is associated with a breach of vascular integrity in NASH.

Background & Aims: In non-alcoholic fatty liver disease (NAFLD), monocytes infiltrate visceral adipose tissue promoting local and hepatic inflammation. However, it remains unclear what drives inflammation and how the immune landscape in adipose tissue differs across the NAFLD severity spectrum. We aimed to assess adipose tissue macrophage (ATM) heterogeneity in a NAFLD cohort.

Outcomes of liver transplantation for hepatopulmonary syndrome in patients with concomitant respiratory disease.

Background & Aims: Concomitant respiratory disease is a common finding in patients with hepatopulmonary syndrome (HPS). Among patients who underwent liver transplantation (LT) for HPS, we compared characteristics and outcome of patients with versus without concomitant respiratory disease.

Methods: This single center retrospective observational study included patients with HPS who underwent LT between 1999 and 2020.

Managing dysfunctions and reinterventions in endoscopic ultrasound-guided choledochoduodenostomy with lumen apposing metal stents: Illustrated technical review (with videos).

Endoscopic ultrasound-guided choledochoduodenostomy (EUS-CDS) with lumen apposing metal stent is emerging both as a rescue strategy and a primary treatment for distal malignant biliary obstruction. The large-scale diffusion of the procedure and improved overall survival of patients with pancreatobiliary neoplasms is resulting in a growing population of long-term EUS-CDS lumen apposing metal stent carriers. Recent studies have reported a need for reintervention during follow-up as high as 55%, and the Leuven-Amsterdam-Milan Study Group classification has been developed, identifying five mechanisms of stent dysfunction and 11 possible rescue strategies aimed at restoring biliary drainage.

Rituximab and improved nodular regenerative hyperplasia-associated non-cirrhotic liver disease in common variable immunodeficiency: a case report and literature study.

Common variable immunodeficiency (CVID) associated liver disease is an underrecognized and poorly studied non-infectious complication that lacks an established treatment. We describe a CVID patient with severe multiorgan complications, including non-cirrhotic portal hypertension secondary to nodular regenerative hyperplasia leading to diuretic-refractory ascites. Remarkably, treatment with rituximab, administered for concomitant immune thrombocytopenia, resulted in the complete and sustained resolution of portal hypertension and ascites.

PERcutaneous transhepatic CHOLangioscopy using a new single-operator short cholangioscope (PERCHOL): European feasibility study.

Objectives: A new short device for percutaneous endoscopic cholangioscopy was recently developed. However, feasibility and safety has not yet been evaluated. The aim of this study was to assess clinical success, technical success, and adverse events (AEs).

Outcomes of minor versus major papilla rendez-vous for EUS-guided pancreatic duct drainage.

Objectives: EUS-guided pancreatic duct drainage (EUS-PD) using rendez-vous has been suggested as a safer alternative to pancreatogastrostomy. Fibrostenotic disease in the pancreatic head may however preclude major papilla rendez-vous, leading to preferential guidewire advancement through the minor papilla. Our aim was to compare the outcomes of minor and major papilla rendez-vous.
