Abstract
Purpose
The purpose of the present study was to explore the risk for complications and reoperations following open repairs for sliding groin hernias.
Method
All primary indirect inguinal hernia repairs registered in the Swedish Hernia Register 1998–2011 were identified. Repeated and bilateral procedures were excluded. The epidemiology, the incidence of per- and postoperative complications, and the reoperation rate due to recurrences were analyzed.
Results
100 240 non-repeated unilateral repairs were registered with sliding hernias in 13 132 (13.1 %) (male 14 %, female 5 %) procedures. The methods of repair for sliding and non-sliding hernias were Lichtenstein and other open anterior mesh repairs (N = 10865, 82.7 % and N = 60790, 69.8 %), endoscopic techniques (N = 136, 1.0 % and N = 4352, 5.0 %), and other techniques (N = 2131, 16.2 % and N = 21966, 25.2 %). In multivariate analyses with adjustment for gender, acute/planned surgery, reducibility, method of repair and age, sliding hernias were associated with a low but slightly increased risk for perioperative complications (hazard ratio 1.30, 95 % confidence interval 1.04–1.62, p = 0.023) and postoperative hematoma (hazard ratio 1.13, confidence interval 1.02–1.26, p = 0.019). There was no increased risk of reoperation due to recurrences.
Conclusion
Compared to older reports, the incidence of repairs due to primary indirect sliding inguinal hernias has increased over time and it is not just a male disease. The overall results are good with low and comparable complication rates, and no increased risk of reoperations due to recurrences.
