Introduction: Spleen stiffness (SS) has been found to mirror dynamic changes in portal pressure after transjugular intrahepatic portosystemic shunt (TIPS) placement. However, there is no data available regarding SS in patients with spontaneous portosystemic shunting (SPSS), especially in regards to prediction of hepatic decompensation.
Methods: We retrospectively selected patients with confirmed SPSS and esophageal varices (EVs) at endoscopic examination, and recorded any decompensating event (i.e., variceal hemorrhage, overt hepatic encephalopathy, refractory ascites, spontaneous bacterial peritonitis, hepatorenal syndrome) in the first twelve months following liver and spleen elastography.
Results: The patients who presented decompensating events showed lower platelet count (94.5 vs. 121.5 g/L, p < 0.001), higher SS (44 vs. 30 kPa, p < 0.001), higher probability of EVs according to SS (77 vs. 2 %, p < 0.001), and higher spleen diameter (14 vs. 12 cm, p = 0.043). They also showed a higher prevalence of splenorenal shunts (66.7 vs. 31.2%), and a significantly wider SPSS major diameter (14.5 vs. 8 mm, p < 0.001).
Conclusion: SS could predict SPSS efficacy in relieving portal pressure, and could predict decompensating events in patients with SPSS.

Differentiating Benign from Malignant Causes of Splenomegaly: Is Acoustic Radiation Force Impulse Elastography Helpful?
Diseases
November 2024
Gastroenterology, Endocrinology, Metabolism and Clinical Infectiology, University Hospital Giessen and Marburg, Philipp University of Marburg, Baldingerstraße, 35037 Marburg, Germany.
Purpose: To evaluate the ability of acoustic radiation force impulse (ARFI) elastography in differentiating benign from malignant etiologies of splenomegaly based on differences in splenic stiffness.
Materials And Methods: Between September 2020 and November 2022, we evaluated 40 patients with splenomegaly-defined by a splenic long axis greater than 13 cm and/or a short axis greater than 6 cm, without visible focal or infiltrative mass lesions-using abdominal ultrasound at our university hospital. Each patient also underwent a standardized ARFI elastographic assessment of the enlarged spleen, with data collected prospectively.

Introduction: Splenic infarction caused by thrombi rarely causes abdominal pain in acute abdomen patients. This report describes a case of splenic infarction caused by thrombus detachment due to paroxysmal atrial fibrillation, which was successfully treated and discharged from the hospital.
Case Presentation: A 52-year-old woman walked into the emergency room with left upper abdominal pain, nausea, and vomiting 12 h prior.

Department of Hepatology, The Third People's Hospital of Taiyuan, Taiyuan, Shanxi Province, China.
Background: Pegylated interferon- (PEG-IFN-α) therapy could decrease hepatitis B surface antigen (HBsAg) and improve long-term prognosis of hepatitis B virus (HBV) infection. However, studies on safety and efficacy of PEG-IFN- for patients with HBV-related cirrhosis are limited.
Methods: This was a single-center study.

Background: Acute decompensation (AD) in patients with liver cirrhosis is associated with a dramatic deterioration in prognosis. Immediate initiation of appropriate recompensation measures is essential to improve patient's outcome, although objective parameters for evaluating the success of recompensation are still lacking. Spleen stiffness measurements (SSM) have emerged as promising non-invasive tool to assess clinically significant portal hypertension (CSPH), which is the main driver of acute decompensation.

Background: Direct measurement of portal venous pressure (PVP) is invasive, so the hepatic venous pressure gradient (HVPG) is commonly measured to evaluate portal hypertension (PH). HVPG is the gold standard for estimating PVP but few reports have covered standardized measurement techniques.
Methods: This study validated standardized techniques for PVP measurement.
