胃肠道吻合口破裂原因的实验研究

An experimental study of the cause of rupture of the anastomosis in gastroenterostomy

动物实验证实，吻合口破裂原因不在于缝合层次多少，只要妥善缝合其粘膜下层，吻合口缝针间隙一般不会发生破裂。肠腔压力过大所致破裂往往发生在针孔眼的逐渐扩大、进而形成针孔连线上的撕裂。因此，胃肠道吻合时，缝针宜细小一点，针距应适当，以０５ｃｍ为宜。缝合过密，层次过多则有害无益。

This experiment confirmed that the cause of rupture of the anastomosis in gastroenterostomy did not depend upon the layers of suture The rupture of anastomosis did not occur between the needle suture points if the submucosa was properly sutured, it may occur when the needle suture hole was gradually enlarged and connected each other So, it is reasonable that the distance of suture points should be kept about 0 5cm If the distance is too short or the suture layers are too many, it is not good for the healing of the anastomosis
