Summary

Laparoscopic surgery causes a lower systemic stress response compared to open surgery, evidenced by reduced C-reactive protein (CRP) levels. This approach is beneficial for major operations like nephrectomy, limiting acute phase reactions.

Area of Science:

  • Minimally Invasive Surgery
  • Surgical Trauma Response
  • Inflammatory Markers

Background:

  • Laparoscopic surgery aims for equivalent operative outcomes with reduced patient trauma.
  • Systemic stress response is a key differentiator between surgical approaches.
  • Understanding inflammatory markers like CRP and IL-6 is crucial for assessing surgical impact.

Purpose of the Study:

  • To compare the systemic stress response between laparoscopic and open surgical procedures.
  • To evaluate the impact of surgical approach on inflammatory markers (IL-6, IL-10, CRP).
  • To determine if laparoscopy offers advantages in minimizing operative trauma.

Main Methods:

  • Prospective, controlled, nonrandomized study involving female pigs and 145 human patients.

  • Procedures included laparoscopic and open surgeries (nephrectomy, varix ligation) and ESWL.
  • Serum levels of interleukin-6 (IL-6), interleukin-10 (IL-10), and C-reactive protein (CRP) were measured pre- and post-operatively.

    • Main Results:

    • Laparoscopy significantly reduced serum CRP levels during and after procedures in both animals and patients.
    • Open surgery resulted in higher CRP elevations compared to laparoscopic approaches.
    • IL-6 levels were less elevated with laparoscopy and minor procedures than with open nephrectomy; IL-10 showed no significant differences.

    Conclusions:

    • The surgical approach, rather than the procedure's extent, strongly correlates with the acute phase reaction.
    • Laparoscopic access effectively limits systemic acute phase reactions for major operations like nephrectomy.
    • For minor procedures, laparoscopy provides technical benefits, though invasiveness differences are less pronounced.
