[Technique of repair of acquired inguinal hernia by anterior reinforcement of the Fruchaud floor with polypropylene mesh]

Abstract

The main cause of acquired inguinal hernia is weakness of Fruchaud's deep muscolofascial floor, following metabolically-determined collagen disorders. A technique for the anterior reinforcement of this structure with polypropylene mesh is described here. Following intermuscular decollement, the mesh is placed in direct contact with the surface formed by the transversalis fascia and the transversus abdominis muscle and stretched as extensively as possible. Because the posterior aspect of the inguinal canal is the true barrier to abdominal pressure, the author believe that its direct reinforcement, without interposition of the internal oblique muscle, constitutes the most correct anatomo-surgical approach to hernia repair. This is the case for both indirect hernias, in which the internal ring is reconstructed at a deeper level, and for direct hernias, in which the "tent effect" of the prosthesis is prevented. Ninety-two primary inguinal hernias (56 indirect, 29 direct and 7 direct and indirect) in 87 patients were repaired with this technique. Seventy-nine patients were followed up from 2 to 24 months. Early complications included: 7 ecchymosis, 3 seromas, 2 subcutaneous infections, 3 testicular swellings. Incision and testicular pain for longer than 6 months occurred in 2 cases. No prosthetic infections or recurrences have been detected up to the present.
