Systemic inflammatory responses during laparoscopic and open inguinal hernia repair: a randomised prospective study

Area of Science:

• Surgical Inflammation and Immunology
• Minimally Invasive Surgery

Background:

• Inguinal hernia repair is a common surgical procedure.
• Understanding the inflammatory response post-surgery is crucial for patient recovery.

Purpose of the Study:

• To compare the inflammatory responses following laparoscopic versus open inguinal hernia repair.
• To assess differences in serum inflammatory mediators and recovery times.

Main Methods:

• A randomized prospective study involving 18 male patients with unilateral inguinal hernias.
• Patients underwent either laparoscopic or open tension-free repair.
• Serum levels of various inflammatory markers (IL-2Ralpha, IL-6, TNF-alpha, etc.) were measured pre- and post-operatively.
• Operation duration and time to return to normal activities were recorded.

Main Results:

• Serum IL-6 levels increased significantly in both groups, but more so after open repair.
• Tumor Necrosis Factor (TNF)-alpha and soluble TNF receptor II (sTNF-RII) showed no significant changes.
• Soluble TNF receptor I (sTNF-RI) increased in both groups, with no intergroup difference.
• Interleukin-2 receptor alpha (IL-2Ralpha) decreased significantly in both groups.
• Laparoscopic repair had a longer operative time but a significantly faster return to normal activities (2 days vs. 13 days).

Conclusions:

• Laparoscopic inguinal hernia repair is associated with less surgical trauma, as indicated by a milder postoperative inflammatory response.
• The findings suggest potential benefits of laparoscopic repair in terms of patient recovery.
• Larger randomized studies are recommended to confirm the clinical relevance of these findings.
