Summary
When no inguinal hernia is found during surgery, performing no repair is recommended. This approach avoids the risk of chronic pain and does not increase recurrence rates in patients undergoing planned inguinal herniorrhaphy.
Area of Science:
- General Surgery
- Surgical Outcomes
Background:
- Planned inguinal herniorrhaphy can be challenging when no hernia is identified.
- Limited large-scale data exist regarding the incidence of negative findings in hernia repairs.
- Current recommendations for surgical intervention in such cases are lacking.
Purpose of the Study:
- To investigate the incidence of negative findings in planned inguinal herniorrhaphy.
- To analyze recurrence rates and reoperation outcomes in patients where no hernia was found.
- To provide evidence-based recommendations for managing cases with no identifiable hernia during surgery.
Main Methods:
- Analysis of data from the Danish Hernia Database (1998-2002).
- Inclusion of 42,356 groin hernia repairs.
- Categorization of patients with no hernia into groups (lipomas, no pathology, weak abdominal wall) for surgical technique analysis.
Main Results:
- No hernia was found in 313 out of 42,356 cases (0.74%).
- 11 reoperations (3.5%) were performed, with no significant difference based on initial surgical approach (herniorrhaphy vs. no repair).
- Recurrence rates were not higher in patients who did not undergo repair when no hernia was initially found.
Conclusions:
- A small percentage of planned inguinal herniorrhaphies reveal no hernia.
- Performing no repair when no hernia is found is associated with a low reoperation rate.
- Avoiding surgical repair in cases of negative findings may mitigate the risk of chronic postherniorrhaphy pain.
