OBJECTIVE: Postoperative intra-abdominal adhesions are a major source of postsurgical morbidity. Pelvic irradiation increases the likelihood of adhesion development. The purpose of this study was to evaluate the effects of hyaluronic acid-carboxymethylcellulose film, which was designed as a barrier to prevent adhesions, on the healing of ileal anastomoses performed on irradiated rat bowel.
STUDY DESIGN: Sixty-eight female Sprague-Dawley rats underwent whole pelvic irradiation with a single fraction of 1700 cGy. Twenty weeks later the rats underwent exploratory laparotomy with segmental ileal resection and reanastomosis. Eighteen of the anastomoses were wrapped in hyaluronic acid-carboxymethylcellulose film. Fifty anastomoses were not treated with any adhesion-inhibiting barrier. On the fifth postoperative day the animals underwent another laparotomy for evaluation of the anastomotic sites.
RESULTS: At the second laparotomy 93% of the rats treated with hyaluronic acid-carboxymethylcellulose film were found to have perianastomotic abscesses. In the non-hyaluronic acid-carboxymethylcellulose film group the perianastomotic abscess rate was 24% (P <.0001).
CONCLUSION: Among previously irradiated rats undergoing small-bowel resection and anastomosis, hyaluronic acid-carboxymethylcellulose film was associated with a markedly increased rate of abscess formation at the operative site.
