Summary
Laparoscopic inguinal hernia repair with mesh offers faster recovery and less pain compared to open surgery. However, it involves longer operation times and a higher risk of visceral and vascular injuries, with no significant difference in recurrence rates compared to open mesh repair.
Area of Science:
- General Surgery
- Minimally Invasive Procedures
- Hernia Repair
Background:
- Inguinal hernia repair is a common general surgery procedure.
- Synthetic mesh has become standard, utilized in both open and laparoscopic approaches.
- Previous trials were often too small to definitively compare techniques.
Purpose of the Study:
- To compare minimal access laparoscopic mesh techniques with open surgical techniques for inguinal hernia repair.
- To analyze recurrence rates, complications, and recovery times between the two methods.
Main Methods:
- Systematic review and meta-analysis of randomized controlled trials (RCTs) and quasi-RCTs.
- Inclusion of published and unpublished trials regardless of language.
- Individual patient data (IPD) were obtained and analyzed where possible.
Main Results:
- Laparoscopic repair resulted in longer operative times but earlier return to usual activities (7 days sooner).
- Laparoscopic repair showed reduced rates of persisting pain and numbness.
- No significant difference in hernia recurrence was found between laparoscopic and open mesh repair; however, laparoscopic repair showed reduced recurrence compared to open non-mesh repair.
Conclusions:
- Laparoscopic mesh repair is associated with faster recovery and less post-operative pain and numbness.
- While recurrence rates are similar to open mesh repair, laparoscopic techniques carry a higher risk of visceral and vascular injuries.
- The choice between laparoscopic and open mesh repair involves balancing benefits of faster recovery against increased operative risks.
