目的:研究手术中应用奈维加强颈部食管胃吻合口的方法是否可以增强食管胃吻合口的抗拉力。方法:选取新鲜离体猪食管及猪胃制作食管胃吻合模型,第一步试验,找到模型受牵拉时吻合口薄弱点,第二部试验,通过测定抗拉力,评价奈维对吻合口薄弱点的加强作用。结果:吻合口薄弱位置位于食管肌层,加奈维组吻合口的抗拉力为27.56 ± 2.51 N,高于无奈维加强组的抗拉力(P < 0.001)。结论:试验的结果表明,在体外模型中使用奈维作为加强材料增大了吻合口的抗拉力,应用奈维加强吻合口薄弱部位可能减少吻合口瘘的发生。 Objective: To study whether the cervical esophagogastric anastomosis can be strengthened by the application of Neoveil ® to strengthen the tensile strength of the esophagogastric anastomosis in surgery. Methods: The esophagogastric anastomosis model was made by fresh isolated pig esoph-agus and stomach; in experiment 1, the weak point of the model was clarified; in experiment 2, we evaluated the effect of Neoveil ® to strengthen the weak point of the anastomosis by measuring the tensile strengthen. Results: The weak point of the anastomosis was the esophageal muscular layer and the tensile strengthen of anastomosis in group with Neoveil was 27.56 ± 2.51 N, which was significantly higher than the group with no Neoveil ® reinforcement. Conclusion: These findings suggests that the use of Neoveil ® as a buttressing material increased the tensile strength of the anastomosis in this ex vivo model, reinforcement of the weak point of the anastomosis with Neoveil® may lead to fewer anastomotic leaks.
