PURPOSE:
To evaluate an experimental animal model to study the abdominal tissue activity considering its interaction with a polypropylene mesh, through the use of one of the optical phenomena of light Laser, the biospeckle.METHODS:
Fifty Wistar male rats were divided into four groups Group 1 ten animals not submitted to surgery; Group 2 ten animals submitted to surgery without polypropylene mesh; Group 3 20 animals submitted to surgery followed by the mesh placement; Group 4 (sham) with ten animals. None of the animals presented post surgical complications being submitted to the optical tests at the 20th postoperative day.RESULTS:
The analysis from the biospeckle tests, comparing the medians and standard deviations with T Student test, indicated that no significative difference was observed on the abdominal wall tissue activity in the four groups considered, with and without polypropylene mesh prosthesis implantation.CONCLUSION:
The animal model is viable and the biospeckle open ways for a great number of experiments to be developed in evaluating tissue activity.
