The implantation of a mesh is an essential step in laparoscopic inguin
al hernia surgery. We present the case of a 22-year-old man who develo
ped an unspecific and refractory syndrome of inguinal pain after a TAP
P procedure for a primary inguinal hernia. Repeated reoperation for re
movement of clips and nerve transection were unsuccessful. By a transi
nguinal approach, 18 months after the first operation we removed a pre
peritoneal Prolene mesh which had shrunk and folded to 30 % of its ori
ginal size. The problem of biocompatibility of meshes currently used i
n inguinal hernia surgery is discussed.
