Abstract

Objective: Peridural fibrosis after laminectomy is an important surgical problem. Tenoxicamis a nonsteroidal antiinflammatory drug and an oxicam derivative acting by inhibiting theformation of prostaglandin and eicosanoids. Low dose methotrexate which has been used asan antiinflammatory agent rhomatoid arthritis inhibits the synthesis of potentially toxiccompounds those accumulate in inflamed tissues. The aim of this study was to evaluate andcompare the efficacy of these two independent pharmacological agents in the inhibition ofperidural fibrosis.Methods: L3-4-5 bilateral laminectomy with sparing the dura mater integrity was perfomedto 30 male Wistar albino rats. Except the SHAM group, low dose methotraxate (0.2 mg/kg) ortenoxicam (0.5 mg/kg) was administered on the dura mater before the surgical closure. After42 days, all rats were euthanized and their spinal columns performed laminectomy wereremoved for the histopathological evaluation.Results: The peridural fibrosis grades of the groups administered low dose methotrexate ortenoxicam were lower than SHAM group grades. They have lower fibroblast counts thanSHAM group numerically, although there was no statistically significant difference amonggroups.Conclusion: Local usage of low dose methotrexate and tenoxicam may be helpful option forprevention of peridural fibrosis after laminectomy procedures in future.

Özet

Amaç: Laminektomi sonrası epidural fibrozis önemli bir cerrahi problemdir. Tenoksikamprostaglandin ve eikosanoidlerin oluşmasının azaltılmasında rol alan bir oksikam türevi vesteroid olmayan antienflamatuar bir ilaçtır. Düşük doz metotreksat potansiyel toksikbileşiklerin sentezini ve inflamasyon dokusunda bunların birikimini azaltan, yaygın kullanılanbir antimetabolit ajandır. Bu çalışmanın amacı epidural fibrozisin azaltılmasında iki bağımsızfarmokolojik ajanın etkinliğinin karşılaştırılması ve değerlendirilmesidir.Yöntem: 30 erkek Wistar albino rat laminektomi modeli için kullanılmıştır. Dura bütünlüğükorunarak L3-4-5 laminektomi yapılmış, kontrol grubu haricindeki hayvanlara metotreksat(0,2mg/kg) ya da tenoksikam (0,5mg/kg) dura üzerine uygulanmış ve takiben cerrahi yarausulüne uygun şekilde kapatılmıştır. 42 gün sonra tüm hayvanlara ötenazi uygulanmış velaminektomi yapılan spinal kolon parçası histopatolojik inceleme için tek parça halindeçıkarılmıştır.Sonuç: Epidural fibrozis düzeyi düşük doz metotreksat ve tenoksikam uygulanan gruplardakihayvanlarda kontrol grubundakilerden düşük seviyede tespit edilmiş, ancak fibroblast sayılarıbakımından gruplar arasında istatistiksel yönden belirgin fark saptanmamıştır. Yapılan buçalışma sonunda laminektomi sonrası gelişebilecek epidural fibrozisin önlenmesinde düşükdoz metotreksat ve tenoksikamın lokal kullanımının yararlı bir seçenek olabileceği kanısınavarılmıştır.
