Cytokine levels after open and laparoscopic cholecystectomy

Area of Science:

• Immunology
• Surgical Science

Background:

• Cholecystectomy is a common surgical procedure.
• Understanding the inflammatory response post-cholecystectomy is crucial for patient recovery.

Purpose of the Study:

• To compare serum cytokine and cortisol levels between laparoscopic cholecystectomy (LC) and open cholecystectomy (OC).
• To analyze the kinetic changes in these inflammatory markers following both surgical procedures.

Main Methods:

• Prospective study involving 28 patients (14 LC, 14 OC).
• Serum samples analyzed for interleukin-1 beta (IL-1 beta), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-alpha), and interleukin-10 (IL-10) using ELISA.
• Cortisol levels measured via radioimmunoassay.
• Samples collected pre-surgery, 24 hours post-surgery, and 7 days post-surgery.

Main Results:

• Significantly higher IL-6 levels were observed in the OC group compared to the LC group (p < 0.05).
• IL-1 beta, IL-10, TNF-alpha, and cortisol levels did not show significant differences between the groups.
• IL-6, IL-1 beta, and TNF-alpha levels increased 24 hours post-surgery and normalized by 7 days.
• Overall cytokine concentrations were consistently higher in the OC group.

Conclusions:

• Laparoscopic cholecystectomy is associated with a less pronounced inflammatory response, specifically lower IL-6 levels, compared to open cholecystectomy.
• The inflammatory markers studied generally normalize within a week after surgery.
• IL-1 beta and IL-10 demonstrated the most stability, with cortisol also showing relative stability.
