应用镍钛记忆合金加压吻合夹进行结肠吻合的临床研究

目的评价一种新型的镍钛记忆合金加压吻合夹（CAC）进行结肠吻合的安全性及有效性。方法2005年4月至2006年2月，南京军区南京总医院将30例结肠癌病人随机分为两组，各15例。研究组使用CAC进行结肠吻合，对照组使用常规吻合器进行结肠吻合。术后观察有无发生与吻合相关的并发症，肠道排气、排便时间，CAC的排出时间。结果两组术后均无吻合口瘘、吻合口狭窄或梗阻等并发症发生。术后肠道排气、排便时间无差异。研究组CAC于术后8～14d均排出体外。结论应用CAC进行结肠吻合安全可靠．使用简便。

Colonic anastomosis performed by the nickel-titanium temperature-dependent memory-shape device

Objective This study was designed to evaluate compression anastomosis clip (CAC) for colonic anastomosis.Methods Thirty patients with colonic cancer were assigned randomly to undergo an anastomosis either with the CAC or a stapler.The following parameters will be recorded: anastomotic complication;first post-operation flatus and bowel movement;extrusion of clip device.Results Neither group had anastomotic complications such as leakage or obstruction.The clip is expelled with the stool within 8-14 days.Two group had the similar results in recovery of bowel function.Conclusions Our study demonstrates that this CAC is safe and simple to use for colonic anastomosis.
