[Comparative experimental study of colocolic anastomosis with manual suture and biofragmentable ring].
The authors undertook an experimental trial, in order to compare one layer interrupted sutured large bowel anastomosis with that of biofragmentable anastomotic ring (BAR). This device creates an inverted serosa-to-serosa anastomosis. It is designed to fragment after hydrolysis and it is passed within the faeces after healing of the anastomosis. Fourteen dogs were operated on, having been performed 28 anastomoses, 14 with conventional way and 14 with the BAR, both in the same bowel, on alternate sequence and 10cm from each other.
