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 sacrificed 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.
本研究旨在比较采用三种不同吻合技术的犬结肠吻合口破裂压力（ABP）。在48只犬的结肠三个等距部位切断后，依次采用生物可降解吻合环（BAR）、吻合器和缝合进行结肠吻合。将48只犬分为四组，每组12只，分别在术后0天、3天、7天或28天处死，测定ABP和破裂壁张力。数据显示，BAR吻合口在手术当天强度最大，缝合吻合口在第三天最强，到第7天时所有吻合口强度相当。到第28天时，所有组的破裂压力接近正常结肠破裂压力，任何差异可能反映了吻合口纤维化及其他因素的变化。
