Biochemical liver function after partial hepatic resection with or without partial hepatic vascular exclusion.

Area of Science:

• Hepatobiliary Surgery
• Surgical Oncology
• Transplant Surgery

Background:

• Liver resection is a common procedure for hepatic malignancies.
• Minimizing ischemia-reperfusion injury is crucial for preserving remnant liver function.
• Liver vascular partial exclusion (LVPE) is a technique used to reduce blood flow during liver resection.

Purpose of the Study:

• To evaluate the safety and impact of liver vascular partial exclusion (LVPE) during partial hepatectomy.
• To assess the advantages and disadvantages of LVPE concerning liver dysfunction due to ischemia.

Main Methods:

• A comparative study involving 114 patients undergoing partial hepatectomy.
• 57 patients underwent LVPE, while 57 served as a control group.
• Mitochondrial function and serum aminotransferases were measured post-surgery.

Main Results:

• No significant differences in mitochondrial function were observed between minor and major liver resections.
• Postoperative peak aminotransferase levels were similar in patients with and without LVPE.

Conclusions:

• LVPE did not induce mitochondrial dysfunction in hepatic tissue.
• Aminotransferase levels remained comparable, indicating LVPE is safe.
• LVPE does not cause significant ischemia-reperfusion injury in the liver remnant.
