Abstract

Objective: This study aimed to analyze the effect of an absorbable hemostat produced from oxidized regenerated cellulose (ORC) on pelvicadhesion formation in a rat model using an adhesion scoring system and immunohistochemical staining. Methods: This randomized, controlled experimental study included 20 female Wistar-Albino rats that were equally divided into the followinggroups: control and absorbable hemostat groups. The uterine horns of all the rats were exposed by laparotomy and using 10 W bipolar cautery.Five standard lesions were applied to the antimesenteric areas of each uterine horn. The experimental group received an absorbable hemostatto the traumatized uterine surfaces, whereas the control group did not. After a 28-day follow-up period, a relaparotomy was performed,and adhesions were evaluated based on an adhesion scoring system, and histological sections from areas with adhesion were obtained forimmunohistochemical staining. Immunohistochemical staining included analysis of Ki-67 (proliferation index), CD-31 (neovascularization index),and Masson Trichrome [(MTC) fibrosis and collagen formation index]. Additionally, acute and chronic inflammation indices were determined viapolymorphonuclear leukocytes (PMNL) and mononuclear leukocytes (MNL), respectively. Results: The intensity and scope of adhesion and overall adhesion ratings were substantially higher in the absorbable hemostat group than thecontrol group (2.8±0.85 vs. 2.2±0.53, 0.92±0.26 vs. 0.61±0.25, and 3.72±0.96 vs. 2.81±0.75, respectively). Staining results for Ki-67, CD-31,MTC, PMNL, and MNL were also significantly higher in the absorbable hemostat group than in the control group (p

Özet

Amaç: Bu çalışmanın amacı, okside rejenere sellülozdan (ORC) üretilen absorbe edilebilir bir hemostatın rat modelinde pelvik adezyon oluşumuüzerindeki etkisini adezyon skorlama sistemi ve immünohistokimyasal boyama kullanarak değerlendirmektir. Gereç ve Yöntem: Çift kör, randomize, kontrollü bir deneysel çalışma tasarlandı. Yirmi dişi Wistar-Albino rat eşit olarak kontrol ve absorbeedilebilir hemostat gruplarına ayrıldı. Tüm ratların uterin hornları laparotomi ile ortaya çıkarıldı ve her uterus hornunun antimezenterik yüzeyine10 W bipolar koter kullanılarak beş standart lezyon uygulandı. Deney grubunda travmatize olmuş uterin yüzeylere absorbe edilebilir hemostatuygulanırken, kontrol grubuna herhangi bir müdahale yapılmadı. Yirmi sekiz günlük bir takip süresinin ardından tekrar laparotomi yapıldı veadezyon skorlama sistemine göre adezyonlar değerlendirildi ve immünohistokimyasal boyama için adezyonlu alanlardan histolojik kesitler alındı.İmmünohistokimyasal boyama, Ki-67 (proliferasyon indeksi), CD-31 (neovaskülarizasyon indeksi) ve Masson Trikrom [(MTC), fibrozis ve kollajenoluşum indeksi] analizini içeriyordu. Ek olarak, sırasıyla polimorfonükleer lökositler (PMNL) ve mononükleer lökositler (MNL) aracılığıyla akut vekronik enflamasyon indeksleri belirlendi. Bulgular: Adezyon şiddeti ve yaygınlığı ile toplam adezyon skorları, kontrollere kıyasla absorbe edilebilir hemostat grubunda anlamlı düzeydedaha yüksekti (sırasıyla: 2,8±0,85’e karşı 2,2±0,53, 0,92±0,26’ya karşı 0,61±0,25 ve 3,72±0,96’ya karşı 2,81±0,75). Ki-67, CD-31, MTC, PMNL veMNL için boyama sonuçları da emilebilir hemostat grubunda kontrol grubuna göre anlamlı düzeyde daha yüksekti (tümü için p
