Summary
The spleen enlarges during liver regeneration after surgery. Splenic growth correlates with remnant liver volume, suggesting shared regulatory mechanisms between these organs.
Area of Science:
- Hepatology
- Regenerative Medicine
- Surgical Oncology
Background:
- The relationship between liver regeneration and spleen size is not well understood.
- Liver resection, particularly following portal vein embolization (PVE), provides a model to study liver regeneration.
Purpose of the Study:
- To investigate serial changes in liver and spleen volumes after liver resection.
- To explore the correlation between liver regeneration and splenic enlargement.
Main Methods:
- Computed tomography (CT) was used to monitor liver and spleen volumes in 24 patients undergoing liver resection for biliary cancer.
- Measurements were taken before PVE, after PVE, and at 14 days, 28 days, and 1 year after hepatectomy.
Main Results:
- Remnant liver volume significantly increased post-hepatectomy, reaching 76% of pre-PVE total liver volume after 1 year.
- Splenic volume increased by 179% by 28 days after hepatectomy and remained enlarged at 1 year.
- The rate of splenic volume increase within 14 days post-hepatectomy correlated significantly with remnant liver volume increase (r=0.64, p=0.0006).
Conclusions:
- The spleen enlarges concurrently with liver regeneration.
- These findings suggest that the liver and spleen may share common growth regulatory mechanisms.
