title: Evaluation of resorbable barriers for preventing surgical adhesions.
abstract: OBJECTIVE
  To evaluate the ability of collagen film, collagen gel, sodium hyaluronate/carboxymethylcellulose film, and fibrin glue to prevent adhesion formation.
  
  
  METHODS
  Randomized trial using a rat model of a standardized abdominal wound and cecal wound.
  
  
  METHODS
  University research laboratory.
  
  
  METHODS
  Sprague-Dawley female rats.
  
  
  METHODS
  Resorbable barriers or no barrier (controls) were placed between an abdominal wall wound (1 cm x 2 cm) and a similarly sized cecal wound.
  
  
  METHODS
  Adhesion formation between wounds was assessed and quantitated 7 days after surgery.
  
  
  RESULTS
  Without treatment, 34 of 35 untreated rats (97%) developed adhesions. Treatment with collagen gel (3 of 33 rats), collagen film (3 of 10 rats), or sodium hyaluronate/carboxymethylcellulose film (2 of 10 rats) significantly reduced the incidence of adhesion formation. Treatment with fibrin sealant resulted in 9 of 10 animals having adherent wounds 7 days after surgery.
  
  
  CONCLUSIONS
  Resorbable barriers of collagen gel, collagen films and sodium hyaluronate/carboxymethylcellulose film were effective in significantly reducing adhesion formation. Fibrin sealant at 7 days had an incidence of adhesion formation similar to that in untreated control animals.
