Summary

Laparoscopic cholecystectomy causes fewer immune system changes than open laparotomy. Immune parameters like T cells and NK cells were less affected by laparoscopy, indicating a potentially gentler surgical approach.

Area of Science:

  • Immunology
  • Surgical Oncology
  • Minimally Invasive Surgery

Background:

  • Surgery can induce transient immunodepression, typically resolving within 15-20 days.
  • Understanding the immunological impact of different surgical techniques is crucial for patient recovery.

Purpose of the Study:

  • To compare the immunological effects of laparotomic and laparoscopic cholecystectomy.
  • To identify differences in cellular and humoral immunity parameters between the two surgical approaches.

Main Methods:

  • Measured various immune parameters (IgG, IgA, IgM, C3, C4, granulocytes, lymphocytes, T cells, NK cells, etc.) before and at 24 hours, 7 days, and 14 days after surgery.
  • Analyzed data from 12 patients undergoing laparotomic cholecystectomy and 25 patients undergoing laparoscopic cholecystectomy.

  • Utilized flow cytometry for cell surface marker analysis (e.g., CD11c, CD19, CD3, CD4, CD8, CD16, CD14, CD25, HLA-DR, CD57).

    • Main Results:

    • Granulocyte counts significantly increased in both groups, with a more pronounced and sustained rise in the laparotomy group.
    • Total T cells, T helper cells, and NK cells decreased at 24 hours post-surgery exclusively in the laparotomy group.
    • Laparoscopy was associated with less significant alterations in key immune cell populations compared to laparotomy.

    Conclusions:

    • Laparoscopic cholecystectomy appears to induce less substantial immunological changes than laparotomic cholecystectomy.
    • The findings suggest that minimally invasive approaches like laparoscopy may offer advantages in preserving immune function post-surgery.
