Insights
Spleen-dedicated vibration-controlled transient elastography (VCTE) accurately predicts esophageal varices in children with portal hypertension. This non-invasive method aids in managing and screening for this condition.
Area of Science:
- Pediatric Gastroenterology
- Hepatology
- Medical Imaging
Background:
- Portal hypertension in children can lead to serious complications like esophageal varices.
- Accurate non-invasive methods are needed for early detection and risk stratification.
Purpose of the Study:
- To assess the diagnostic accuracy of splenic stiffness measurement (SSM) using spleen-dedicated vibration-controlled transient elastography (VCTE).
- To predict the presence of varices and varices needing treatment (VNT) in children with clinically evident portal hypertension (CEPH).
Main Methods:
- A prospective cross-sectional study included children aged 6 months to 14 years with CEPH.
- SSM was measured using a spleen-specific VCTE probe (100 Hz).
- Esophagogastroduodenoscopy (EGD) was used for variceal detection and risk stratification.
Main Results:
- SSM showed good accuracy in predicting varices (AUC: 0.86) and VNT (AUC: 0.838).
- Higher SSM values correlated with the presence and severity of varices (p < 0.001).
- Specific thresholds for SSM demonstrated significant sensitivity and specificity for varices and VNT.
Conclusions:
- Spleen-dedicated VCTE-measured SSM is a reasonably accurate tool for predicting varices and VNT in children with CEPH.
- Integrating SSM into clinical practice can support the screening and management of pediatric portal hypertension.
Objective:
To evaluate the diagnostic accuracy of splenic stiffness measurement (SSM) using spleen-dedicated vibration-controlled transient elastography (VCTE) for predicting varices and varices needing treatment (VNT) in children with clinically evident portal hypertension (CEPH).
Methods:
In this single-centre prospective cross-sectional study, children aged 6 months to 14 years with portal hypertension meeting the criteria for CEPH were eligible. SSM was measured using the VCTE with a spleen-specific (100 Hz) probe. Esophagogastroduodenoscopy (EGD) was performed to detect varices and risk stratification. Diagnostic performance was assessed using receiver operating characteristic analysis and contingency tables.
Results:
Ninety-three consecutive children with CEPH underwent EGD, and successful SSM acquisition was achieved in 90 cases. The median (interquartile range) age of presentation was 6 (3-10) years. EGD identified varices in 79 (87.8%) and VNT in 57 (63.3%). Children with varices had higher median SSM values than those without (37.9 vs. 17.9 kPa; p < 0.001). Among those with varices, SSM values were higher in high-risk than in low-risk cases (42.9 vs. 21.9 kPa; p < 0.001). SSM demonstrated good accuracy for predicting varices (area under the curve: 0.86, 95% confidence interval: 0.76-0.97) with a sensitivity of 75.9% (65.0%-84.9%) and specificity of 90.9% (58.7%-99.8%) at a threshold of 31.1 kPa. For VNT, accuracy was 0.838 (0.702-0.877), with a sensitivity of 87.7% (76.3%-94.9%) and specificity of 72.7% (54.5%-86.7%) at the SSM cut-off of 31.4 kPa.
Conclusion:
In children with CEPH, spleen-dedicated VCTE estimated SSM to have a reasonably high accuracy in predicting varices and VNT. Integrating SSM into clinical practice could assist in the screening and management of portal hypertension in children.
