Prevention of Peritoneal Adhesion Formation with Biomaterial-Degradable Polycaprolactone Film / 中国普外基础与临床杂志

ABSTRACT

Objective To investigate the effects of high molecular bio-degradable film on preventing peritoneal adhesion.Methods One hundred and twenty rats were divided into control group,non-bio-degradable film group and polycaprolactone(PCL) group.Animal models of peritoneal adhesion made by operations on rats serve as control group.In the study,non-bio-degradable film and bio-degradable,namely PCL films sensitive to pseudomonas enzyme,were put into the opening of peritoneum.The effect of the films on peritoneal adhesion was examined on 1,3,7 and 30 d after operation.Results Peritoneal adhesion was found in all the rats of control group and very low in PCL group and non-bio-degradable film group.Conclusion PCL film can effectively prevent the formation of postoperative peritoneal adhesion.
