Fibrin Sealant Effects on the Ilioinguinal Nerve

ABSTRACTBackground: Chronic pain after mesh repair for inguinal hernia may be related to the trauma to the regional nerves by direct compression with sutures, staples, or tacks during mesh fixation. Fibrin sealant (FS) has been recommended to eliminate this risk. In this experimental study, the effects of FS on the ilioinguinal nerve when a mesh was applied was searched. Materials and Methods: Fifteen New Zealand rabbits were used in three groups. In Group 1, a 2×1 cm, standard monofilament, pure polypropylene mesh was laid over ilioinguinal nerve. In Group 2, 0.5 ml FS was applied on the nerve without using an onlay mesh. In Group 3, a 2×1 cm mesh was laid onlay and secured with 0.5 ml FS with no fixating suture. Three months after surgery bilateral nerve samples were taken from the contiguous nerve segment for microscopic study. Results: Group 1 showed prominent findings with regard to all parameters. There were significant differences between Group 1 and Group 2 in respect of fibrosis, lymphocyte, and ...
