Abstract

AIm: Failed back surgery syndrome is observed in 15% of patients who have undergone surgery for lumbar disk hernia.Excess epidural fibrosis is the etiology in 24% of FBSS cases. This study was conducted with the belief that the antiproliferative effect of temozolomide can prevent epidural fibrosis. MaterIal and Methods: 8 rats (Group I) underwent laminectomy and were then administered saline while 6 rats (Group II) were administered temozolomide at a dose of 18 mg/kg/day for 5 days after the surgery to make up a total of 14 male Wistar rats used. The pathology preparations of subjects sacrificed at the end of week 6 were histopathologically examined with the Hematoxylin-Eosin stain and Trichrome stain. The pathology preparations were assessed with the analysis parameters and scale generated by He et al. The results were analyzed with the Chi- square test. Results: No significant difference was found between the two groups in terms of bone and cartilage regeneration, arachnoidal fibrosis, and inflammatory and fibroblast cell densities. Epidural fibrosis formation was significantly less and there was no grade III fibrosis in the Temozolomide group. This was found to be statistically significant (p=0.0302). No side effect of dural or intradural damage was observed. ConclusIon: Temozolomide was found to be effective in preventing epidural fibrosis. However, further research is required to determine its effectiveness in local applications and the appropriate dose range.

Özet

AMAÇ: Lomber disk hernisi için cerrahi uygulananların %15’inde başarısız bel cerrahisi sendromu görülmektedir. BBCS etyolojisinin de %24’ünü aşırı epidural fibrozis oluşturmaktadır. Bu çalışma temazolomidin antiproliferatif etkisiyle epidural fibrozisi önleyebileceği düşünülerek yapılmıştır. YÖNTEM ve GEREÇLER: Laminektomi uygulanıp serum fizyolojik verilen 8 rat (Grup I) ve operasyon sonrası 5 gün boyunca 18mg/kg/gün dozda olacak şekilde temozolomid verilen 6 rat (Grup II) olmak üzere toplam 14 Wistar cinsi erkek rat kullanıldı. 6. hafta sonunda sakrifiye edilen deneklerin patolojik preparatları, Hematoksilen Eozin ve Trikrom boyalarıyla histopatolojik incelemeye alındı. Patolojik preparatlar He ve arkadaşlarının oluşturduğu analiz parametreleri ve skala ile değerlendirildi. Çıkan sonuçlar Ki-kare testiyle değerlendirildi. BULGULAR: Her iki grup arasında kemik ve kıkırdak rejenerasyonu, araknoidal fibrozis, inflamatuvar ve fibroblast hücre yoğunluğu açısından anlamlı fark saptanmadı. Epidural fibrozis oluşumu ise Temozolomid grubunda belirgin daha azdı ve grade III fibrozise hiç rastlanmadı. Bu istatistiki olarak da anlamlı bulundu (p=0,0302). Yan etki olarak dura ve intradural yapılarda hasarlanma tespit edilmedi. SONUÇ: Temozolomidin epidural fibrozisi önlemede etkili olduğu saptanmıştır. Ancak özellikle lokal uygulamada etkinliğinin ve uygun doz aralığının saptanması için ileri araştırmalar gerekmektedir.
