Hypersplenism

Splenectomy may relieve hypersplenism, reverse liver fibrosis, improve hepatic functional reserve, and reshape the systemic antitumor immune milieu by removing the source of negative immunomodulation. This prospective cohort study aims to enroll patients undergoing laparoscopic hepatectomy combined with splenectomy for small hepatocellular carcinoma（HCC） with a preoperative platelet count \<80×10\^9/L. The study will evaluate the dynamic changes in hepatic functional reserve, immune function, and risk of HCC recurrence through five post-surgical time points（3, 6, 12, 18, and 24 months after surgery）. The endpoints include hepatic functional reserve（ICG-R15, Child-Pugh score, ALBI score, etc.）, immune function indicators（peripheral blood lymphocyte subsets: CD4\^+ T cells, CD8\^+ T cells, regulatory T cells, NK cells, etc., and serum cytokine profiles）, and HCC recurrence rate within 2 years after surgery（confirmed by imaging）. This trial will provide evidence to optimize surgical strategies for patients with small HCC complicated with hypersplenism.

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 .

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

This study aimed to evaluate the effectiveness and safety of vagus nerve-guided laparoscopic splenectomy and azygoportal disconnection, and to assess its impact on postoperative digestive complications and quality of life.
