Author contributions: Liu XF performed research design, draft the manuscript and data analysis; Huang XC draft the manuscript, performed the data collection and performed the statistical analysis; Ye QJ performed the statistical analysis and patient follow-up; Yuan LJ performed the data collection and management; Gao GF performed patient follow-up; Li JY and Feng DP performed research design, helped to draft the manuscript and analytical guidance. All authors have read and approve the final manuscript. Li JY and Feng DP contributed equally to the work and should be regarded as co-corresponding authors. In contemporary academic research, designating two co-corresponding authors is increasingly recognized as a valid and often necessary practice, reflecting the complex and collaborative nature of scientific inquiry. The primary justification lies in accurately representing substantial, distinct, and indispensable contributions to both the project's execution and its communication. Many projects exhibit complementary expertise domains where leadership is genuinely shared. This study represents a collaborative achievement between the fields of ultrasound imaging and interventional medicine, necessitating the allocation of professional tasks by two corresponding authors. Feng DP, an expert in interventional medicine, is responsible for that aspect of the work, while Li JY oversees the ultrasound medicine component. Designating both individuals as corresponding authors clearly indicates their equitable partnership and shared responsibility for the integrity of the work, future correspondence, data oversight, and accountability. This approach transcends traditional single-correspondent models, which might otherwise obscure the true dynamics of collaborative leadership essential for large-scale, interdisciplinary projects. This practice is in line with evolving guidelines, such as those from the ICMJE, which emphasize the importance of substantial contributions, and ensures that authorship fairly reflects the intellectual and logistical leadership that underpins the research.

Abstract
BACKGROUND

The impact of transjugular intrahepatic portosystemic shunt (TIPS) on liver and spleen stiffness remains unclear, as does the association between preoperative liver and spleen stiffness and prognosis following TIPS.

AIM

To investigate changes in liver and spleen stiffness after TIPS and examines the relationship between these parameters and the prognosis of post-TIPS patients.

METHODS

A total of 76 patients with liver cirrhosis and portal hypertension who underwent TIPS were included. Liver and spleen stiffness was assessed using the sound touch quantify (STQ) value, determined via point shear wave elastography in ultrasound imaging. Cox regression analysis was employed to evaluate the relationship between liver and spleen stiffness and cumulative survival in TIPS patients.

RESULTS

The liver STQ value demonstrated a marginally decreasing trend over time (P = 0.052), while the spleen STQ value showed a significantly decreasing trend (P = 0.025). Spleen STQ was positively correlated with portal pressure gradient (PPG) levels (rs = 0.327, P = 0.025). Cox regression analysis indicated that older age [hazard ratio (HR) = 1.063, 95%CI: 0.997-1.133, P = 0.060] and a higher liver STQ value (HR = 1.051, 95%CI: 1.009-1.095, P = 0.018) were associated with an increased mortality risk after TIPS. No significant correlation was found between liver or spleen stiffness and overt hepatic encephalopathy post-TIPS. The liver STQ value [area under the receiver operating characteristic curve (AUC) = 0.724 (95%CI: 0.563-0.884)] showed superior predictive performance compared to the Child-Pugh score [AUC = 0.699 (95%CI: 0.529-0.870)] and was comparable to the model for end-stage liver disease score [AUC = 0.746 (95%CI: 0.591-0.902)].

CONCLUSION

Following TIPS, spleen stiffness exhibited a more pronounced change than liver stiffness and was positively associated with PPG. Preoperative liver stiffness serves as a prognostic indicator for survival in patients undergoing TIPS.

Core Tip: This study involved 76 patients with liver cirrhosis who underwent a transjugular intrahepatic portosystemic shunt (TIPS). The stiffness of the liver and spleen was assessed using point shear wave elastography with ultrasonic imaging, which quantifies the sound touch value. The results indicated that spleen stiffness significantly decreased over time following TIPS. Older age and higher liver stiffness were correlated with an elevated risk of mortality following TIPS. In summary, following TIPS, spleen stiffness exhibited a more pronounced change than liver stiffness. Preoperative liver stiffness serves as a prognostic indicator for survival in patients undergoing TIPS.
