Laparoscopic cholecystectomy (LCHE) causes less immune system interference than open cholecystectomy (CHE). While both procedures temporarily affect monocyte function, LCHE allows for quicker immune recovery, indicating a potentially milder impact on immune defense.

Area of Science:

  • Immunology
  • Surgical Oncology

Background:

  • Cholecystectomy is a common surgical procedure.
  • Immune system function can be affected by surgical interventions.
  • Laparoscopic cholecystectomy (LCHE) is a minimally invasive approach compared to open cholecystectomy (CHE).

Purpose of the Study:

  • To compare the effects of LCHE and CHE on immune defense mechanisms.
  • To evaluate changes in monocyte and T-lymphocyte function post-surgery.
  • To assess the expression of key immune cell surface molecules.

Main Methods:

  • Prospective evaluation of immunological data from patients undergoing LCHE and CHE.
  • Analysis of T-lymphocyte proliferation and monocyte/lymphocyte/granulocyte cell surface molecule expression.
  • Blood sample collection preoperatively and at specified postoperative time points.

Main Results:

  • Monocyte HLA-DR expression decreased post-LCHE and CHE, with faster recovery after LCHE.
  • Antigen-presenting capacity of monocytes and T-lymphocyte proliferation remained unimpaired in both groups.
  • CD25 expression increased post-CHE, indicating T-cell stimulation, but not post-LCHE.

Conclusions:

  • LCHE demonstrates less interference with immune defense compared to CHE.
  • Monocyte HLA-DR levels normalize faster after LCHE.
  • While immune changes are noted after CHE, their clinical significance requires further investigation.
