377. Neue Aspekte zur histologischen Aufarbeitung experimenteller Darmanastomosen

Summary The histologic reaction was examined in suture loops of experimental intestinal anastomoses. A special procedure was developed. Sections were taken from the knot area and from between the knots, as well as longitudinal to the anastomosis. Colonic anastomoses were sutured in male Wistar rats in accordance with eight technical parameters (apposition, number of layers, stitch, distance from the wound edge, distance between knots, type and position of the knot, suture tension, suture material). The suture tension was varied in only three strengths (no tension and medium and strong tensions). The tissue damage due to the suture tension could thus be demonstrated.
