Researchers determined that a spleen stiffness reading of 40 kPa or lower can effectively rule out high-risk varices in patients with chronic portal vein thrombosis. This non-invasive test allows clinicians to identify patients who may safely bypass traditional endoscopic screening.
Why it matters
Standard liver stiffness metrics designed for cirrhosis are ineffective for patients with noncirrhotic portal vein thrombosis. This new threshold provides a reliable alternative for assessing variceal risk without requiring an invasive procedure.
A 40 kPa spleen stiffness threshold correctly identified high-risk varices in 95% to 97% of patients across two cohorts. Implementing this cutoff could have prevented over 40% of screening endoscopies performed during the study.
The players
Journal of Hepatology
This peer-reviewed medical journal publishes clinical research and advancements in the field of liver disease.
The details
Using vibration-controlled transient elastography, researchers evaluated a total of 346 patients across derivation and validation cohorts. The spleen stiffness measurement was found to be the only variable independently associated with the presence of high-risk varices.
Timeline
The findings were published in the Journal of Hepatology in 2026.
The Big Picture
This diagnostic threshold marks a shift away from reliance on established liver stiffness cutoffs for cirrhosis when treating patients with portal vein thrombosis. It provides a specialized diagnostic framework that avoids the diagnostic errors seen when applying cirrhotic protocols to noncirrhotic patients.
Patients with chronic portal vein thrombosis may benefit from reduced exposure to invasive upper endoscopy procedures. By using this non-invasive elastography measurement, doctors can potentially minimize diagnostic risks and patient discomfort.
The takeaway
This diagnostic tool represents a significant advancement in personalized care for those with portal vein thrombosis. Patients should consult their hepatologist to determine if non-invasive elastography is an appropriate alternative to traditional endoscopic screening in their specific case.
