Effects of different pulmonary surfactants in the prevention of postoperative intraabdominal adhesion formation

BackgroundAfter abdominal surgery, the formation of postoperative adhesion is a serious problem. The aim of the study is to evaluate the efficacy of 2 different pulmonary surfactants, poractant and beractant, on adhesion prevention in an experimental model.Materials and MethodsAn experimental intraabdominal adhesion model was created in 18 adult female rats by cecal abrasion. The rats were randomly assigned to 3 groups. Group I received no further treatment, whereas groups II and III received intraperitoneal poractant and beractant, respectively, before closing the incision. On the 15th postoperative day, all rats underwent relaparotomy, intraabdominal adhesions were scored macroscopically according to Canbaz scoring system, and the cecum in each animal was evaluated microscopically.ResultsThe median adhesion scores of group II and III rats were significantly lower when compared with group I (P = .02). Group III had a lower median adhesion score than did group II, but this did not reach significance (P > .05).ConclusionThese observations suggest that intraperitoneal instillation of both pulmonary surfactants is associated with lower adhesion scores, higher adhesion-free cases, and improved histologic findings.
