The Adhesions are a common and unfortunate consequence of most abdominal surgical operations. Some patients form extensive permanent adhesions that can cause abdominal or pelvic pain, infertility and bowel obstruction. Epidemiological studies have highlighted the extent of this problem and the cost to the health service, and although there are numerous approaches to prevent adhesions formation by decreasing peritoneal injury, the use of various adhesion barriers and topical pharmacological agents, no method so far has proved completely efficacious in randomized controlled trials. In this study, it decided to evaluate the effects of peritoneal exposure to Pentoxifylline in post-surgical adhesions in rats. Twenty female Sprague-Dawley rats underwent laparotomy. Postoperative peritoneal adhesions was induced by scarping serosal the surface of the colon. The animals were divided randomly into two experimental groups: a group treated with Pentoxifylline, and a control group. And were killed and evaluated at 15 postoperative days, decrease was observed in the number (p=0,025), severity (p=0,0018), extension (p=0,0013),density (p=0,0071), inflammation (p=0,0020), vascular proliferation (p=0,0007) and fibrosis score (p=0,0047) of adhesions in the group treated with Pentoxifylline, when compare to control group. In conclusion, this study demonstrated that the administration of Pentoxifylline intraperitoneally decrease significantly the peritoneal adhesions formation, and thus, may be useful for its prevention of same.
