Abstract
The study was undertaken to compare anastomotic bursting pressure (ABP) of colorectal canine anastomoses using three different anastomotic techniques. Biofragmentable anastomotic ring (BAR), stapled, and sutured colon anastomoses were sequentially placed in each of 48 dogs following division of the colon at three equally spaced sites. Four groups of 12 dogs were sacritficed either on day 0, 3, 7, or 28 and ABP and bursting wall tension were determined. The data revealed that BAR anastomoses have the greatest strength on the day of surgery, sutured anastomoses are the strongest on the third day and all are comparable by the 7th day. Bursting pressures for all groups by day 28 approach normal colonic bursting pressure, with any differences likely to be a reflection of variation in anastomotic fibrosis and other factors.
Résumé
Cette étude a été réalisée pour comparer la pression de rupture anastomotique de l'anastomose colo-rectale chez le chien utilisant trois différentes techniques d'anastomose. Anneau anastomotique biofragmentable (AAB), pince à suture automatique et suture manuelle ont été placées de façon séquentielle chez chacun des 48 chiens après section du colon en trois endroits placés à égale distance. 4 groupes de 12 chiens ont été sacrifiés au jour 0, 3, 7, 28, la pression de rupture anastomotique et la tension pariétale de rupture ont été étudiées. Les résultats révèlent que les anneaux anastomotiques biofragmentables ont une plus grande force le jour de l'intervention, les anastomoses manuelles sont plus solides au troisième jour et toutes sont comparables au septième jour. La pression de rupture pour tous les groupes au 28ème jour approche la pression colique normale de rupture avec quelques différences qui reflêtent probablement des variations de la fibrose anastomotique ou d'autres facteurs.
