Effect of Laparoscopic Splenectomy on Renal Function in Cirrhotic Patients With Hypersplenism (2-Year Follow-Up) (LS-RF)
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
調査の概要
詳細な説明
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

Glomerular filtration rate (eGFR)
時間枠:at preoperative baseline, postoperative month 1, month 3, month 6, month 12, month 18, month 24

Change in estimated glomerular filtration rate (eGFR) For females: If serum creatinine (Scr) ≤ 0.7 mg/dL: eGFR = 142 × (Scr/0.7)^(-0.241) × (0.9938)^Age; If Scr > 0.7 mg/dL: eGFR = 142 × (Scr/0.7)^(-1.200) × (0.9938)^Age. For males: If Scr ≤ 0.9 mg/dL: eGFR = 142 × (Scr/0.9)^(-0.302) × (0.9938)^Age; If Scr > 0.9 mg/dL: eGFR = 142 × (Scr/0.9)^(-1.200) × (0.9938)^Age. Note: Results are in mL/min/1.73 m².
