胃肠道吻合口破裂原因的实验研究

The experimented study on the cause of the rupture of gastroenterostomy

胃肠道吻合术不论是采用一层还是二层吻合法，通过动物实验证实，其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。破裂往往发生在针孔眼的逐渐扩大并进而形成的针孔连线上。因此，缝针宜细小一点，针距应适当，缝合过密、层次过多有害无益。

In gastroenterostomy with one-layer or twolayer suture,it was confirmed that the cause of rupture of gastroenterostomy stoma did not depened upon the layers of suture by the animal experiment.The rupture of anastomosis did not happen between the sutures so long as the submucosa was properly sutured.The rupture may happened when the needle hole was increasingly enlarged and connected suturing too tightly and too many layers was not good for healing.
