摘要
目的 探讨小功率 CO2 激光对老龄大白鼠食管组织焊接的优越性。方法 对 90只老龄 (月龄 1 8～ 2 0个月 )大白鼠颈段食管激光焊接和手法缝合进行对比实验 ,分别观察两种方法组织学改变及吻合口瘘的发生率。结果 激光焊接较手法缝合组织损伤轻 ,周围炎症反应弱 ,食管吻合口修复快 ,瘢痕形成少 ,吻合口瘘发生率低 ,二者差异显著 (P<0 .0 5)。结论 激光焊接食管组织切实可行 。
Objectives To discuss the advantages of welding the esophageal tissues of rat by low CO_2 laser.Methods Two methods, i.e, welding by laser and sewing up by hands were performed for the neck esophageal tissues of 90 old rats (18～20 months old), and the histological changes as well as the occurrence rates of anastomosis leak were observed respectively.Results The tissue injures were lighter, the inflammatory reactions of the surrounding were weaker, the esophageal anastomosis repair were faster, the scar formations were less and the occurrence rates of anastomosis leak were lower ( P <0.05) by laser welding than that led to by sewing up by hands.Conclusions Welding esophagus using laser is practical, and it is worth further to investigate and to use this method in the clinical.
