Properties of abdominal wall intraperitoneal implants were assessed in vivo on 76 rabbits. Implants of polytetrafluorethilene (PTFE), uncoated mesh polypropylene and polypropylene with one- and two-side collagen coat, oxycellulose and polyoxibutirate coated implants were compared. Animals were extracted from the experiment on 14, 90 and 210 days with further implant assessment. PTFE and collagen-coated prostheses showed the least number of adhesions. Retraction was 5-14%. Prosthetic integration into the abdominal wall varied. PTFE and collagen-coated polypropylene proved to be the most appropriate materials for intraperitonel mesh hernia plasty.
