Abstract

AIm: Postlaminectomy epidural fibrosis is the formation of scar tissue over the dura mater following posterior spinal surgery. This devastating complication is responsible for the substantial amount of failed back syndromes. Ma terIal and Methods: Twenty male Wistar-Albino rats each weighing 350-400 grams were used. Following L3-L5 laminectomy, the rats were randomly divided into 2 groups, with 10 rats in each group. In the control group, only a laminectomy was performed. In the drug group, 5 mg/ml tacrolimus was topically applied with a cotton pad soaked with the drug solution for 5 minutes. The animals were killed on the 30th postoperative day injecting a lethal dose (250 mg/kg) of pentobarbital and the involved dural segments were removed for histopathological and ultrastructural evaluations. Results: Epidural scar thickness and the density were significantly lower in the animals treated with tacrolimus than those of the control group. ConclusIon: Promising evidence regarding the anti-scar potential of tacrolimus merits further research to optimize the dosage and the usage of the drug.

Özet

AMAÇ: Laminektomi sonrası oluşan epidural fibrozis, posterior spinal stabilizasyon cerrahisini takiben dura mater üzerinde yara dokusu oluşumuyla karakterizedir. Bu ciddi komplikasyon, başarısız bel cerrahisi sendromunun da en önemli nedenlerinden biridir. YÖNTEM ve GEREÇler: Her biri 350-400 gram ağırlığında yirmi adet erkek Wistar-Albino sıçan kullanılmıştır. L3, L4 ve L5 laminektomiyi takiben sıçanlar sayıları eşit iki gruba rastgele olacak şekilde ayrılmışlardır. Kontrol grubundaki sıçanlara sadece laminektomi uygulanırken, deney grubundaki sıçanlara laminektomi sonrası 5mg/ml takrolimus solüsyonu topikal olarak 1*1 cm’lik pamuk parçalarına emdirilerek 5 dakika boyunca uygulanmıştır. Ratlar operasyon sonrası 30. günde ölümcül doz olan 250mg/kg pentobarbital verilerek öldürülmüş ve ilgili dura segmentleri histopatolojik ve ultrastrüktürel incelemeler için çıkarılmışlardır. BULGULAR: Epidural yara dokusu kalınlığı ve yoğunluğu takrolimusla muamele edilen sıçanlarda kontrol grubundakilere göre belirgin olarak daha az bulunmuştur. SONUÇ: Çalışmamızda, saptanan takrolimusun anti-skar etkisi,doz ve kullanım şeklinin belirlenmesi açısından daha ileri çalışmaları gerektirmektedir.
