结肠肛管吻合本两层吻合方法的实验观察

Experimental Observation on Two-layer Technipue of Suture in Colo--anal Anastomosis

用狗做结肠肛管吻合术，对照组按Ｐａｒｋｓ方法行结肠肛管套式吻合，试验组同前吻合后在吻合口上方０．８ｃｍ处再行第２层缝合。术后１、２、８周处死动物，肉眼及光镜检查吻合口。两组各５条狗中，对照组发生吻合口漏２例；试验组吻合口均愈合良好。离体抗张测验两种吻合方法有显著性差异。结果说明，两层吻合方法增加了吻合口抗张能力，而对血供无影响涸而可有效地防止吻合口漏。

controlled trial of one- and tWo--layer techniques of suture for colo- anal anastomosis wasdone on 1 0 dogs. The speAnens of anastomesis were examined by- naked eye aam taler 'microscope for1, 2 and 8 weeks respectively after the animals wcre killed. No Dnastomotic leakage occurred in 5 dogsin which two- layed technique of suture were Performed but 2 dehiscences in the control group. Thereare significant difference between two types of anastomosis in the test of tensile strength. The resultsof the experiment show that the tWo- layer technique of suture of Colo- anal anastomosis is helpful inincreasing the tensile strength of the anastomesis, and doesnt affect the blood supply to theanastomosis. so' that this tWo- layer technique of suture Can be used for Preventing anastomosis leakageeffectively.
