Purpose: Partial splenic artery embolization (PSAE) is an effective procedure for cirrhotic patients with hypersplenism. The aim of our study is to evaluate the effect of PSAE on skeletal muscle, and to identify the predictor for an improvement in skeletal muscle index (SMI) in cirrhotic patients with hypersplenism after PSAE.
Materials And Methods: 466 cirrhotic patients with hypersplenism underwent PASE between Dec 2013 and Mar 2022. Medical records and CT images of enrolled patients were analyzed.
Results: 105 cirrhotic patients with hypersplenism were enrolled. Sarcopenia was observed in 60.00 % (63/105) of these patients, 68.25 % (43/63) of male patients, and 31.75 % (20/63) of female patients. In cirrhotic patients, no significant change in the mean SMI at the third lumbar vertebra (L3) level after PSAE. In patients with sarcopenia, the L3 SMI increased from 36.77 cm/m (baseline) to 43.38 cm/m (P < 0.01), the L3 subcutaneous fat area (SFA) increased from 79.16 cm (baseline) to 103.52 cm (P < 0.01) at 12-month follow-up after PSAE. In patients without sarcopenia, the L3 SMI decreased from 58.38 cm/m (baseline) to 49.44 cm/m (P < 0.05), the L3 SFA increased from 89.63 cm (baseline) to 94.77 cm (P > 0.05) at 12-month follow-up after PSAE. Univariate and multivariate analysis demonstrated splenic infarction rate (OR: 0.01, P = 0.0032) and SMI (OR: 0.84, P < 0.001) were independent predictors for an improvement in skeletal muscle in patients with sarcopenia.
Conclusions: In cirrhotic patients with sarcopenia, an improvement in skeletal muscle and fat mass was observed after PSAE; splenic infarction rate and the L3 SMI before PSAE predicted an improvement in skeletal muscle index in patients with sarcopenia after PSAE.

Hepatic encephalopathy (HE) is traditionally associated with hepatic parenchymal diseases, such as acute liver failure and cirrhosis. Its prevalence in non-cirrhotic portal hypertension (NCPH) patients, extrahepatic portal vein obstruction (EHPVO), and non-cirrhotic portal fibrosis (NCPF) is less well described. HE in NCPH allows one to study the effect of portosystemic shunting and ammonia without significant hepatic parenchymal injury.

Objectives: This study aimed to analyze the direct healthcare costs and early complications associated with pretransplant portal vein thrombosis (PVT) in cirrhotic patients undergoing their first orthotopic liver transplant (LT) at a hospital in Colombia from 2013 to 2021.
Methods: A registry-based retrospective follow-up study was conducted on cirrhotic patients aged 14 years or older who underwent their first LT at the San Vicente Fundación Rionegro Hospital between January 2013 and April 2021. The primary outcomes were early (30-day) vascular and biliary complications and direct healthcare costs.

Introduction EUS-guided gall bladder drainage (EUS-GBD) for management of symptomatic gallbladder disease has been shown to be safe and effective in high surgical risk patients with data lacking in patients with cirrhosis. We sought to study the safety and effectiveness of EUS-GBD in cirrhotic compared to non-cirrhotic patients. Methods Retrospective review of patients who underwent EUS-GBD at four (3 US and 1 Spain) international tertiary care centers.

Background: Blood loss during liver transplantation (LT) remains a major concern associated with increased morbidity and reduced patient and graft survival. The high complexity of the procedure associated with the multifaceted origin of the bleeding urges early identification of high-risk patients and proper monitoring of hemostasis disorders in order to improve results. The accuracy of international normalized ratio (INR) and activated partial thromboplastin time (aPTT) to evaluate coagulation status in cirrhotic patients has been doubted.

The aim of this study is to determine the epidemiological and bacteriological profile of spontaneous bacterial peritonitis, as well as antibiotic resistance among hospitalized patients at CHU Mohammed VI, in order to guide empirical antibiotic choices for better management. Methods: This is a prospective study conducted over a period of 12 months, from January to December 2023, focusing on all requests for bacteriological examination of ascitic fluid samples.
