Abstract

Inflammation during the early phase of anastomotic wound healing is an essential cellular response and is suppressed by corticosteroids. The anti-inflammatory effect of corticosteroids is largely responsible for its impairment of wound healing in bowel anastomosis. Beta-D-glucan, a commonly used macrophage activator, has been shown to improve anastomotic wound healing under normal conditions. In the present study, we have investigated the effects of beta-D-glucan on anastomotic wound healing in rats treated with long-term corticosteroid. 92 male Sprague-Dawley rats were randomized into four groups. 1 : control, 2: control + beta-D-glucan, 3 : steroid, 4 : steroid + beta-D-glucan. Methylprednisolone (5mg/kg) was injected IM daily for 14 days in groups 3 and 4. After 14 days, following anaesthesia and laparotomy, colonic anastomosis was performed 3 cm away from the peritoneal reflection of rectum. In groups 2 and 4, 100mg/kg beta-D-glucan was administered orally for 7 days before laparotomy. On postoperative day 3, relaparotomies were performed and bursting pressures, hydroxyproline levels and histopathological specimens were studied. The mean values of bursting pressures groups were 50.8 (95% CI 46.99-56.50), 58.2 (95% CI 54.49-...Continue Reading
