Abdominal hernia repair is one of the most common surgical procedures. Current data indicate that the best treatment results are achieved with use of synthetic material to reinforce weakened abdominal wall. Prosthetic materials utilized for hernia repair induce adhesions with underlying viscera. They should be therefore separated from them by a layer of peritoneum otherwise adhesions may cause to serious complications such as bowel-skin fistulas. The aim of our work was to determine if implantation of our collagen membrane into abdominal wall defect induce adhesions in rat model of ventral hernia. The collagen film was obtained by acetic acid extraction of rat tail tendons and than casting the soluble fraction onto polyethylene shits. Abdominal wall defect was created in 10 Wistar male rats. Collagen membranes were implanted into the defect using interrupted polypropylene stitches. After 3 months of observation all animals were sacrificed. No adhesions between path structure and bowel developed. In one often rats (10%) adhesion between fixating stitch and omentum was observed. Complete mesothelium lining and vascular ingrowth were microscopically observed within implanted structure. Promising result requires further confirmation in a larger series of animals.
