Effect of LSD on Lipid Profiles in Cirrhosis Patients With Portal Hypertension Bleeding (2-Year Follow-Up) (LSD-LPPH)

2026年5月10日 更新者：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 Lipid Profiles in Patients With Liver Cirrhosis, Portal Hypertension Bleeding.

Patients with liver cirrhosis frequently exhibit dyslipidemia due to impaired hepatic lipid synthesis, altered bile acid metabolism, and portal hypertension. Laparoscopic Splenectomy and Azygoportal Disconnection (LSD) is commonly used to treat Cirrhosis with Portal Hypertension Bleeding in these patients, but its impact on lipid profiles over 2 years remains poorly characterized. This study will follow patients undergoing LSD to measure changes in serum lipid parameters before and after surgery, identify risk factors for lipid profile deterioration or improvement, and determine whether LSD can ameliorate dyslipidemia in the long term, thereby informing metabolic management strategies in cirrhotic patients.

详细说明

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). Laparoscopic splenectomy combined with azygoportal disconnection (LSD) is commonly used to treat portal hypertension bleeding in these patients, but its impact on lipid profiles over 2 years remains poorly characterized. This study will follow patients undergoing LSD to measure changes in serum lipid parameters before and after surgery, identify risk factors for lipid profile deterioration or improvement, and determine whether LSD can ameliorate dyslipidemia in the long term, thereby informing metabolic management strategies in Cirrhosis with Portal Hypertension Bleeding in these patients.Study Design: Prospective, single-center, observational cohort study with a total duration of 24 months (2 years). Patients with Cirrhosis with Portal Hypertension Bleeding scheduled for elective LSD 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 Azygoportal Disconnection and perioperative short-term lipid monitoring Months 7-24: Long-term follow-up at 3, 6, 9,12, 24 months postoperativelyMonth 24: Data analysis and study completion.
