Hyaluronic acid-carboxymethylcellulose film and perianastomotic adhesions in previously irradiated rats.

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.
