INTRODUCTION: Peritoneal adhesions, the fibrotic bands that form between the surfaces in the peritoneal cavity following surgery, still pose a difficult clinical challenge. AIM: To evaluate the SprayShield™ Adhesion Barrier System (PEG ester amine solution and a buffer solution) in reducing post-operative adhesion formation. MATERIAL AND METHODS: This was a prospective, multi-center, randomized, single blind study. A total of 11 subjects diagnosed with ulcerative colitis (UC) or familial adenomatous polyposis (FAP) were randomized: 8 to the SprayShield™ arm and 3 to the control arm. SprayShield™ was applied on the viscera directly under the midline peritoneal incision and at the site of ileostomy. During the follow-up surgery, the incidence, extent, and severity of post-operative adhesion formation were evaluated, as well as the time required to mobilize the ileal loop. RESULTS: In patients who received SprayShield™ the time required to mobilize the ileal loop at the ileostomy closure was slightly shorter and the incidence and severity of adhesions were somewhat lower vs. control subjects (NS). CONCLUSIONS: SprayShield™ was found to be easy to use, safe, and quick to apply, and performed well in adherence and conformity. The incidence and severity of adhesions were lower for SprayShield™ subjects vs. control subjects, but due to the limited number of patients there are not enough data to confirm the effectiveness of the SprayShield™ Adhesion Barrier System in prevention of adhesions.
