[Anastomosis healing in the irradiated colon. III. Microangiographic studies. An animal experiment study]

During an experimentation on animals, the vascularization of anastomoses in the recto-sigmoidal region was investigated by microangiographic examinations after an irradiation corresponding to the therapeutic proceeding in man. The anastomoses were performed with and without fibrin coating one day, four weeks, eight weeks and four months following to irradiation. The examinations were performed on the third, seventh, 14th, and 21th postoperative day. The results of microangiography do not show any difference between irradiated and non-irradiated animals.
