Abstract

Mechanical intestinal obstruction is a difficult-to-diagnose surgical emergency, especially in the early stage. Clinical and radiological evaluation are the main methods for the diagnosis. Metabolic, inflammatory and ischemic changes occur during intestinal obstruction. No specific biochemical parameters related to diagnosis and severity of intestinal obstruction have been found. In this experimental study, we investigated serum tumor necrosis factor alpha L-glutamate and L-lactate levels as biochemical markers which reflect phys-iopathological processes in two different stages of intestinal obstruction. Methods: Mechanical obstruction was created in Wistar rats with distal Heal ligation. Animals were divided into five groups (Control, Sham-12, Sham-24, Intestinal obstruction 12 and intestinal obstruction-24) and each group consisted of 10 rats. Blood samples were taken 12 and 24 hours after Sham and intestinal obstruction operations. Tumor necrosis factor a levels were measured by ELISA. Serum L-glutamate and L-lactate levels were measured by colorimetric method. Results: Glutamate levels were significantly high especially in the early stage, whereas tumor necrosis factor a increase was significant only in late stage of intestinal obstruction. Serum lactate levels were similar among the groups. Conclusion: Serum glutamate levels may have a potential role as a biochemical parameter contributing to diagnosis, especially in the early stages of intestinal obstruction.

Özet

Mekanik intestinal obstrüksiyon, özellikle erken evrede tanısı güç olan cerrahi bir acildir. Tanı, esas olarak klinik ve radyolojik verilerle konulur. Fizyopatolojik süreçte metabolik, inflamatuvar ve iskemik değişiklikler gözlenir. Henüz hastalığı ve şiddetini gösteren özel bir biyokimyasal parametre bulunmamaktadır. Bu deneysel çalışmada, bu süreçleri yansıtan 3 bağımsız biyokimyasal parametre (tümör nekroz faktör-alfa L-glutamat ve L-laktat), hastalığın 2 farklı döneminde araştırılmıştır. Yöntem: Her biri 10 Wistar rattan oluşan 5 grup oluşturuldu (Kontrol, Shaml2, Sham24, Intestinal obstriksiyon-12, Intestinal obstriksiyon-24). Sham gruplarında laparatomiden 12 ve 24 saat sonra; mekanik intestinal obstriksiyon gruplarında (in-testinal obstriksiyon-12, Intestinal obstriksiyon-24) distal Heal ligasyondan 12 ve 24 saat sonra kan örnekleri alındı, tümör nekroz faktör alfa düzeyleri ELISA ile; L-glutamat ve L-laktat düzeyleri kolorimetrik yöntemle ölçüldü. Bulgular: Intestinal obstriksiyon'nun erken döneminde L-glutamat; geç döneminde tümör nekroz faktör alfa düzeyleri anlamlı yüksek bulundu. L-laktat düzeyleri bakımından gruplar arasında fark yoktu. Sonuç: Serum glutamat değerleri, intestinal obstriksiyon'nun özellikle erken dönemlerinde tanıya katkı sağlayıcı biyokimyasal bir parametre rol oynayabilir.
