[The blood supply of manually sutured and stapled colonic anastomoses].
The blood supply of end-to-end staple and suture lines in the pig colon was compared. In 15 operated animals there was no anastomotic leak. Sporadic circumscribed areas of restricted circulation could be noticed in hand-sewn anastomoses. This effect was marked on the 7th and 14th postoperative day, when vascularisation of the anastomoses was increased. Such lack of vascular supply was not seen in stapled anastomoses. The intramural arteries passed through the B-shaped staples without hindrance. An unremarkable vascular pattern and a completed healing of the anastomoses were observed after 3 weeks in staple lines and after 4 weeks in suture lines.
