Effect of LSD on Renal Function in Cirrhosis Patients With Portal Hypertension Bleeding (2-Year Follow-Up) (LSD-RFPH)

14 mai 2026 mis à jour par: Guo-Qing Jiang, Northern Jiangsu People's Hospital

A Prospective, Single-Center, Observational Cohort Study to Evaluate the Long-Term (2-Year) Effects of Laparoscopic Splenectomy and Azygoportal Disconnection on Renal Function in Patients With Liver Cirrhosis, Portal Hypertension Bleeding

Patients with liver cirrhosis often have impaired or at-risk kidney function due to the close link between liver and kidney (hepatorenal syndrome). Laparoscopic Splenectomy and Azygoportal Disconnection (LSD) is commonly used to treat Cirrhosis with Portal Hypertension Bleeding in these patients, but its impact on kidney function over 2 years is unclear. This study will follow patients undergoing laparoscopic splenectomy to measure changes in kidney function before and after surgery, identify risk factors for kidney damage and whether LSD can improve kidney function in the long term, and help improve care to protect kidney function in cirrhotic patients .

Les conditions

Description détaillée

Liver cirrhosis is associated with systemic hemodynamic disturbances, reduced effective circulating volume, and renal hypoperfusion, creating a high risk of renal dysfunction and hepatorenal syndrome (HRS)-a life-threatening condition reflecting the critical hepatorenal interaction. Patients with cirrhosis, Portal Hypertension Bleeding frequently have subclinical or overt renal impairment preoperatively. LSD is a standard intervention for Cirrhosis Patients With Portal Hypertension Bleeding, but perioperative stress, hemodynamic fluctuations, and surgical trauma may further compromise renal function, and LSD may improve kidney function in the long term. Current evidence lacks prospective, 2-year data on renal function changes after LS in this high-risk population, especially regarding the hepatorenal axis and long-term renal outcomes. This study aims to fill this gap to guide perioperative renal protection strategies.
