Laparoscopic procedures may cause minor liver cell damage, indicated by increased hyaluronic acid (HA) levels. This damage appears clinically insignificant and likely stems from the procedure itself.

Area of Science:

  • Hepatology
  • Surgical Research
  • Cellular Biology

Background:

  • Perisinusoidal cells play a crucial role in liver function.
  • Laparoscopic surgery is increasingly common for various procedures.
  • Understanding the impact of minimally invasive surgery on liver cells is important.

Purpose of the Study:

  • To assess the effect of laparoscopic procedures on perisinusoidal cell function.
  • To investigate potential liver cell damage following laparoscopic surgery.

Main Methods:

  • Serum levels of hyaluronic acid (HA) and beta-N-acetyl hexosaminidase (beta-NAH) were measured in 31 patients undergoing laparoscopic cholecystectomy.
  • A control group of six female patients who underwent unrelated laparoscopic procedures was included.
  • Post-operative liver enzymes (AST, ALT, ALP) and bilirubin levels were monitored.

Main Results:

  • Hyaluronic acid (HA) serum levels significantly increased in both the study and control groups post-laparoscopy.
  • Beta-N-acetyl hexosaminidase (beta-NAH) levels remained within normal limits.
  • Post-operative AST and ALT levels increased significantly only in the study group; ALP and bilirubin levels showed no significant changes.

Conclusions:

  • Laparoscopic procedures can cause detectable damage to Kupffer and endothelial cells, evidenced by elevated HA levels.
  • This observed liver cell damage appears to have no clinical significance.
  • The laparoscopic procedure itself is implicated as the cause of Kupffer and endothelial cell damage.
