Xomed microsutures have recently become available in this country. Three different suture types (10/0 taper needle, 10/0 MET needle, and 11/0 taper needle) were tested for their effect on the patency and strength of the anastomosis 0, 1, and 3 weeks post-operatively. Scanning electron micrographs of an anastomosis with each of the two 10/0 sutures and of both 10/0 needles were also studied. Another standard 10/0 suture (Ethicon) was photographed for comparison. Patency was not affected by suture type. The 10/0 MET needle produced the strongest anastomosis at the time intervals studied. Breaking-load values were highest in all needles 1 week post-operatively. Electron micrographs of the two 10/0 needles show that the MET point is very much sharper than the taper needles. Electron micrographs of the anastomosis indicated that the MET needle also causes less damage around the suture.
Xomed微型缝线最近在该国上市。测试了三种不同类型的缝线（10/0锥形针、10/0 MET针和11/0锥形针）在术后0周、1周和3周对吻合口通畅性和强度的影响。还研究了使用两种10/0缝线和两种10/0针进行吻合的扫描电子显微镜照片。拍摄了另一种标准的10/0缝线（Ethicon）用于比较。通畅性不受缝线类型的影响。在研究的时间间隔内，10/0 MET针产生的吻合强度最强。所有针在术后1周时的断裂负荷值最高。两种10/0针的电子显微镜照片显示，MET针尖比锥形针尖锐得多。吻合口的电子显微镜照片表明，MET针在缝线周围造成的损伤也较小。
