Официальное название
A Prospective, Single-Center, Observational Cohort Study to Evaluate the Short-Term and Long-Term (2-Year) Effects of Laparoscopic Splenectomy on Renal Function in Patients With Liver Cirrhosis, Splenomegaly and Hypersplenism
Обзор
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 is commonly used to treat splenomegaly and hypersplenism 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 laparoscopic splenectomy can improve kidney function in the long term, and help improve care to protect kidney function in cirrhotic patients .
Подробное описание
Rationale: 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, splenomegaly and hypersplenism frequently have subclinical or overt renal impairment preoperatively. Laparoscopic splenectomy (LS) is a standard intervention for hypersplenism, but perioperative stress, hemodynamic fluctuations, and surgical trauma may further compromise renal function and laparoscopic splenectomy may improve the 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.
Study Design: Prospective, single-center, observational cohort study with a total duration of 24 months (2 years). Patients with cirrhosis, splenomegaly and hypersplenism scheduled for elective laparoscopic splenectomy will be enrolled and followed for 2 years to assess renal function dynamics and identify risk factors for renal injury .
Study Timeline:
* Months 1-6: Patient screening, enrollment, baseline assessment * Months 1-18: Laparoscopic splenectomy and perioperative short-term renal function monitoring * Months 7-24: Long-term follow-up at 3, 6, 12, 24 months postoperatively * Month 24: Data analysis and study completion
