Histological Analysis of Intra-Abdominal Adhesions Treated with Sodium Hyaluronate and Carboxymethylcellulose Gel

ABSTRACTPurpose: To evaluate macro and microscopically the adhesions developed after using the anti-adherence compound sodium hyaluronate and carboxymethylcellulose (SH-CBMC) gel and to determine the volume of the adhesions using a stereological estimation. Methods: The study was experimental, random, comparative, and prospective. The subjects of the study were male Wistar rats divided in three groups (n = 10). Group I (control) included rats with no peritoneal injury. Group II rats had a 2 cm diameter injury created bilaterally in the parietal peritoneum at 3 cm from the abdominal midline with electrocautery coated with physiological solution. Group III rats were given the same injuries and coated with SH-CBMC gel. All groups were followed up postoperatively for 30 days, after which a laparotomy was performed to macroscopically determine the presence and type of adhesions. Experimental models were euthanized with anesthetic overdose and biopsies were taken for histopathological examination and stereologi...
