[New method for security by colon anastomoses (author's transl)].

After examinaning the vascular supply of the parietal peritoneum helved peritoneal flaps were fixed in wound dehiscent colon anastomoses. If the vascular supply to the peritoneal flap was sufficient all animals survived without signs of stenosis. It was proved by microangiographic studies that there was an additional vascular supply to the anastomosed colon by the artery of the peritoneal flap.
