Abstract

INTRODUCTION:

Since the introduction of tension-free mesh repair of inguinal hernia ad modum Lichtenstein (L), recurrence rates have been reduced to 1-2%. The bi-layer mesh Prolene Hernia System (PHS) is an alternative mesh with a theoretical potential to further reduce recurrence rates. However, a reoperation due to recurrence after PHS might be technically difficult since both the anterior and posterior space has been utilized.

METHODS:

Data on all males 18-75 years undergoing primary inguinal hernia repair (IHR) with PHS or L between January 1999 and October 2010 was collected from the Swedish Hernia Register (SHR). Moreover, data was collected for all operations due to recurrence after primary IHR with PHS or L between January 1st 1999 and December 31st 2014.

RESULTS:

A total of 1229 primary IHR with PHS and 78,230 with L was identified. Rates of reoperation for recurrence after PHS was significantly lower compared to L (1.5 vs. 2.7 %), [OR 0.38 (0.20-0.74)]. A medial recurrence was most common in both groups. At reoperation, an open anterior mesh repair was used in 74 % after PHS and a posterior mesh repair was performed in 58 % after L. Re-operating time was shorter, although not statistically significant in the PHS group (47 vs. 58 min, p = 0.29). Complication rates after surgery due to recurrence did not differ between groups.

CONCLUSION:

The findings from this dataset suggest that recurrence rates after primary IHR with PHS might be lower and that reoperation due to recurrence after PHS is not more complicated than after L.
