摘要
目的 为了防止气管环形切除后吻合口狭窄，探讨如何增加吻合口矢状径及截面积，避免环形瘢痕的形成。 方法 选用４０ 条杂种幼年犬，随机分为实验组和对照组。两组均切除４ 个气管软骨环。实验组在气管两断端前壁软骨环及膜部各作１ 个“ Ｚ”字形吻合，对照组单纯行对端吻合。两组均采用 Ｖｉｃｒｙ Ｉ３０ 可吸收线缝合及 Ｏ Ｂ胶粘合周围组织覆盖吻合口。待幼犬体重增加１ 倍左右时予以处死。结果 实验组与对照组犬吻合口矢状径梗阻比率分别为１．２０±０．１２ 和０．８３±０．０５；截面积梗阻比率分别为０．９０±０．１２ 和０．６９±０．０９（ Ｐ＜ ００１）。 结论 气管“ Ｚ”字成形术能增加幼犬气管吻合口矢状径和截面积，在防止吻合口狭窄方面优于单纯对端吻合。
Objective To prevent anastomotic stenosis after circumferential resection of trachea, we shed light on the method of increasing the sagittal diameter and cross sectional area in order to avoid formation of circumferential scar tissue. Methods Forty young mongrel canine, weighing 5 7 kg, were randomly divided into experimental group and control group with 20 canine in each. Four rings of trachea were removed from each canine, two “Z” plasty were performed on each canine of experimental group, one on anterior wall and the other on the membranous part of trachea. The control group received simple end to end anastomosis. Vicry Ⅰ 3 0 absorbable suture and OB fibrin glue was used on both groups of canine. All animals were put to death when their body weight doubled approximately. Results At the anatomotic site the average sagittal stenotic ratio were 1.20±0.12 for experimental group and 0.83±0.05 for control group; the average cross sectional area stenotic ratio were 0.90±0 12 and 0.69±0.09 for the two groups respectively ( P<0.01 ). Conclusion The sagittal diameter and cross sectional area of tracheal anastomosis can be increased by using “Z” plasty, which is superior to simple end to end anastomosis in preventing anastomotic stenosis.
