Abstract:
BACKGROUND: Several studies have demonstrated that degradable polycaprolactone film has no apparent influences on cellular immune function of rat critical organs including heart, liver, and kidney, and possesses the prerequisite of anti-adhesion formation.OBJECTIVE: To investigate the role of degradable polycaprolactone film in preventing rat peritoneal adhesion following surgery.DESIGN, TIME AND SETTING: The present randomized, controlled animal experiment was performed at the Department of Physiology, Jilin University.MATERIALS: A total of 120 male Wistar rats, weighing 180-220 g, were included in this study. Peritoneal adhesion was induced in all rats. Non-bio-degradable film was sourced from Wuhan Boster Company, China. Polycaprolactone film was purchased from U.C.C Company. England.METHODS: All 120 rats were randomly divided into 3 groups, with 40 rats per group: control, non-bio-degradable film, and polycaprolactone film. Peritoneal adhesion was induced in all rats. The non-bio-degradahle film and polycaprolactone film groups were subjected to peritoneal wound cover with non-bio-degradable film and polycaprolactone film, respectively. From day 1 following surgery, each rat daily received an intraperitoneal injection of 4 mL 2 g/L pseudomonas enzyme, for a total of 3 successive days.MAIN OUTCOME MEASURES: At 1, 3, 7, and 30 days following surgery, 10 rats were selected from each group for observation of peritoneal adhesion.RESULTS: Totally 120 rats were included in the result analysis. Peritoneal adhesion was successfully induced in rats from the control group. From day 7 following surgery, the peritoneal adhesion rate was significantly lower in the polycaprolactone film group than in the control group (P<0.01). In the non-bio-degradable film group, the peritoneal adhesion rate exhibited decreasing followed by increasing tendency; by day 30, the adhesion rate was significantly higher compared to the polycaprolactone film group (P<0.01).CONCLUSION: Polycaprolactone film is degraded by pseudomonas enzyme to avoid the new adhesion caused by foreign stimulation.
