This study reports the preliminary results of a new totally stapled end-to-end colonic anastomosis in 11 dogs. This "triple-stapled" end-to-end anastomosis was performed with one circular staple line and two linear staple lines, eliminating the need for a colotomy or purse-string suture. The fact that the anvil and anvil stem of a new circular stapling device (Premium EEA) can be detached from the frame of the instrument allows the anvil stem to be brought out through the proximal linear stapled colon. The trocar mounted on the main stem of the circular stapler allows the stem of the main device to be brought out through the distal staple line. Thus, a totally stapled colonic anastomosis is created after mating the anvil stem and main stem of the instrument. The new anastomosis was evaluated radiographically and at necropsy. The use of this technique resulted in no clinically detectable leaks, suggesting that it may facilitate the performance of anterior resections in humans.
本研究报告了11只犬采用新型全吻合器端端结肠吻合术的初步结果。这种“三重吻合”端端吻合术通过一条圆形吻合线和两条线性吻合线完成，无需进行结肠切开术或荷包缝合。新型圆形吻合器（高级端端吻合器）的钉砧和钉砧杆可与器械框架分离，这使得钉砧杆能够通过近端线性吻合的结肠引出。安装在圆形吻合器主杆上的套管针可使主器械的杆通过远端吻合线引出。因此，在将器械的钉砧杆与主杆对接后，即可形成全吻合器结肠吻合。通过影像学检查和尸检对这种新型吻合术进行了评估。使用该技术未发现临床可检测到的渗漏，这表明它可能有助于人类进行前切除术。
