Background And Objectives: Esophageal and gastric fundic varices are common in liver cirrhosis patients. Ultrasound with the Doppler study assesses liver cirrhosis severity, measuring portal vein and splenic indices' association with gastroesophageal varices.
Methodology: This study was conducted on 64 subjects with sonographic features of chronic liver disease who were referred for routine follow-up scans. Portal vein diameter, average velocity, splenic index, congestion index (CI), and portal vein area and velocity were measured.
Result: Subjects with gastroesophageal varices had significantly larger portal vein diameters (14.7±1.64 mm) compared to those without varices (12.05±1.26 mm) (<0.05). Conversely, subjects without varices exhibited a higher portal vein velocity of (17.9±0.6 cm/s) than with varices (13.91±2.01 cm/s) (=0.0005). The splenic index was higher in subjects with varices (1120±494 cm) than those without varices (419 cm) (<0.05). The CI was also higher in subjects with varices. Portal vein velocity showed the highest sensitivity (94%) with a cutoff of 19 cm/s, while the CI had the highest diagnostic accuracy (93.75%) with a cutoff of 0.10 cm xsec. The splenic index demonstrated a sensitivity of 92.85% and diagnostic accuracy of 92.18% with a cutoff of 480 cm. The splenic index followed by the CI is found to be a better predictor of esophageal varices (area under the curve of 96.8 and 96%, respectively).
Conclusion: Ultrasonographic assessment of the portal vein and spleen is a reliable, noninvasive method for predicting gastroesophageal varices in liver cirrhosis. The splenic index and CI have high diagnostic accuracy.

Reduced portal vein blood flow velocity in acute fatty liver of pregnancy.
Front Med (Lausanne)
December 2024
Department of Medical Ultrasound, Jinshan Hospital of Fudan University, Shanghai, China.
Purpose: Acute fatty liver of pregnancy (AFLP) is a severe complication that can occur in the third trimester or immediately postpartum, characterized by rapid hepatic failure. This study aims to explore the changes in portal vein blood flow velocity and liver function during pregnancy, which may assist in the early diagnosis and management of AFLP.
Methods: This longitudinal study was conducted at a tertiary healthcare center with participants recruited from routine antenatal check-ups.

Hepatic insulin clearance is essential for maintaining glucose homeostasis and is closely linked to metabolic disorders such as obesity, insulin resistance, and diabetes. Accurate measurement of insulin clearance is vital for understanding the underlying mechanisms of these conditions. This protocol presents a straightforward and user-friendly hepatic perfusion procedure in mice, specifically designed to directly evaluate the hepatic insulin clearance rate.

Introduction: Acute appendicitis and acute cholecystitis are two of the most commonly encountered surgical entities. Multiple hypotheses are behind their coexistence, which include pathogen predilection, and mucosal ischemia inducing portal vein bacteremia as the management of uncomplicated acute cholecystitis and acute appendicitis is surgical, for which a single operation for synchronous presentation is effective. Here, we report a case with coexistent acute cholecystitis and acute appendicitis managed at our institution.

Portal hypertension is a hemodynamic abnormality that complicates the course of cirrhosis, as well as other diseases that affect the portal venous circulation. The development of portal hypertension compromises prognosis, especially when it rises above a certain threshold known as clinically significant portal hypertension (CSPH). In the consensus conference on Portal Hypertension promoted by the Spanish Association for the Study of the Liver and the Hepatic and Digestive diseases area of the Biomedical Research Networking Center (CIBERehd), different aspects of the diagnosis and treatment of portal hypertension caused by cirrhosis or other diseases were discussed.
