Recurrence and complications after sliding inguinal hernia repair

Area of Science:

• General Surgery
• Surgical Innovation
• Hernia Repair Techniques

Background:

• Sliding hernias are uncommon, and the optimal surgical repair method remains debated.
• Laparoscopic and open (Lichenstein) techniques are commonly used for hernia repair, each with potential benefits and drawbacks.

Purpose of the Study:

• To compare the risk of postoperative complications and reoperation due to recurrence in patients with sliding hernias based on surgical technique.
• Investigate the comparative effectiveness of laparoscopic versus open (Lichenstein) repair for sliding hernias.

Main Methods:

• Retrospective analysis of male patients undergoing hernia repair from January 2010 to December 2017.
• Data sourced from the National Danish Hernia Database, including 32,396 hernia repairs, with 13.5% identified as sliding hernias.

Main Results:

• No significant difference in postoperative complications between sliding and non-sliding hernias at 90 days.
• Lichenstein repair was associated with a slightly higher risk of minor complications (1.9% vs. 0.8%) compared to laparoscopic repair.
• Patients with sliding hernias had a higher recurrence risk (4.3% vs. 2.9%), particularly with Lichenstein repair (OR 2.07).

Conclusions:

• Both laparoscopic and Lichenstein techniques offer safe repair options for sliding hernias with generally low complication and recurrence rates.
• Laparoscopic repair demonstrated a lower risk of recurrence in sliding hernias compared to the Lichenstein technique.
• The study suggests that while both methods are safe, laparoscopic repair may be preferable for sliding hernias to minimize recurrence risk.
