Effect of Laparoscopic Splenectomy on Lipid Profiles in Cirrhotic Patients With Hypersplenism (2-Year Follow-Up) (LS-LP-CH)
A Prospective, Single-Center, Observational Cohort Study to Evaluate the Short-Term and Long-Term (2-Year) Effects of Laparoscopic Splenectomy on Lipid Profiles in Patients With Liver Cirrhosis, Splenomegaly and Hypersplenism

Gedetailleerde beschrijving
Rationale: Liver cirrhosis disrupts hepatic lipid homeostasis through multiple mechanisms, including decreased apolipoprotein synthesis, impaired cholesterol esterification, and altered very-low-density lipoprotein (VLDL) secretion, resulting in characteristic lipid abnormalities such as hypocholesterolemia and low high-density lipoprotein cholesterol (HDL-C). Hypersplenism further complicates this metabolic profile through increased lipid peroxidation and inflammatory cytokine-mediated dysregulation of lipid metabolism. Laparoscopic splenectomy (LS) reduces splenic sequestration and inflammatory burden, potentially improving hepatic lipid synthetic capacity and peripheral lipid clearance. However, perioperative stress responses, anesthetic effects, and abrupt hemodynamic changes may transiently worsen lipid profiles. Current evidence lacks prospective, 2-year data on lipid profile dynamics after LS in this population, particularly regarding the trajectory of total cholesterol, triglycerides, LDL-C, HDL-C. This study aims to fill this gap to guide perioperative metabolic monitoring and long-term dyslipidemia management.
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 lipid profile dynamics and identify risk factors for metabolic deterioration or improvement.
Study Timeline:
Months 1-6: Patient screening, enrollment, baseline lipid assessment Months 1-18: Laparoscopic splenectomy and perioperative short-term lipid monitoring Months 7-24: Long-term follow-up at 3, 6, 9,12, 24 months postoperatively Month 24: Data analysis and study completion
