Effects of antiadhesive agents on the healing of intestinal anastomosis.
OBJECTIVE
The effects of antiadhesive agents on the healing of intestinal anastomosis were investigated.


METHODS
Eighty rats were divided into eight groups. Colotomy and anastomosis were performed to all rats. Saline solution (control), carboxymethylcellulose, aprotinin, verapamil, tenoxicam, cyclosporine, and dextran 70 were administered intraperitoneally. Vitamin E was administered intramuscularly. The rats were killed 15 days later. Anastomotic healing was assessed by bursting pressure and the hydroxyproline content of the anastomotic tissues. The results were evaluated by Mann-Whitney U test.


RESULTS
The mean (+/- standard deviation) bursting pressures of carboxymethylcellulose, cyclosporine, and aprotinin groups (108 +/- 6.73, 122.5 +/-14.39, and 127 +/- 20.23, respectively) were significantly lower than those of the control group (234 +/- 6.19). The mean level of hydroxyproline in the anastomotic tissues was significantly lower in the carboxymethylcellulose and cyclosporine groups (8.92 +/- 0.6 and 8.32 +/- 0.63) than that in the control group (16.33 +/- 0.68).


CONCLUSIONS
These findings indicate that carboxymethylcellulose and cyclosporine had adverse effects on intestinal anastomosis in rats.
