Abstract
In this study we report the effects of flurbiprofen and prostaglandin E2 on anastomotic tensile strength, collagen synthesis, and collagenolytic activity which are in a particularly fine balance in colonic healing. Colonic anastomoses were fashioned in 150 Sprague—Dawley rats which were allocated to receive either 20 mcg prostaglandin E2 in 1 ml saline, 1 ml saline alone (control) intraperitoneally for three days postoperatively, or oral 2.5 mg/kg flurbiprofen daily. Anastomotic bursting pressures, collagen content and collagenolytic activity were measured at three, six, and ten days. It was found that prostaglandin E2-treated animals had significantly weaker anastomoses at three days (102±6.1 mm Hg; m±SEM) compared with the control (126±7.3;P<0.02) or flurbiprofen group (128±4.6;P<0.01) with no differences at six and ten days. Collagen levels were higher in flurbiprofen-treated rats at three days (9.7±0.2 μg hydroxyproline/mg tissue) compared with the control (8.1±0.4 μg/mg;P 0.01) or prostaglandin E2 group (7.2±0.5 μg/mg;P 0.001). These differences were unchanged at six days but were not statistically different at ten days. Collagenolytic activity showed no differences in the three groups during the study. It is concluded that flurbiprofen enhances colonic healing with improved collagen synthesis without affecting collagenolytic activity.
