Objective:
To assess the adhesive potential and incidence of incisional hernia with three meshes.
Design:
Open experimental study.
Setting:
Surgical Research Laboratory, Turkey.
Animals:
75 Wistar albino rats
Interventions:
Abdominal walls were excised, and defects closed primarily or with polyglactin 910, polypropylene, or dura mater. Adhesions were graded and hydroxyproline concentrations measured on days 14 and 180. On day 180, the incidence of incisional hernia, and the grades of inflammation and fibrosis were also recorded.
Results:
The polyglactin 910 group had a higher adhesion grading than the control and dura mater groups on day 14, whereas the polypropylene group had higher adhesion grading than controls. Both polypropylene and polyglactin 910 groups had significantly higher concentration of hydroxyproline than the control and dura mater groups. On day 180, the polypropylene group had a higher adhesion grading than the controls. There were no differences in hydroxyproline concentrations, incidence of hernias, or grading of fibrosis levels among the groups.
Conclusion:
Polyglactin 910 induced more fibrotic adhesions in the early postoperative period whereas polypropylene did in both the early and late postoperative periods.
