应用镍钛记忆合金加压吻合夹进行回肠结肠吻合的临床研究

Nickel-titanium memory-shape alloy compression anastomosis clip for ileocolon anastomosis

目的加压吻合夹(compression anastomosis clip,CAC)已成功地应用于小肠吻合及结肠吻合。文中评价一种新型的镍钛记忆合金CAC进行回-结肠吻合的安全性及有效性。方法将20例放射性肠炎致回盲部不全性肠梗阻的患者随机分为2组,每组各10例。CAC组使用CAC进行回-结肠吻合,对照组使用常规吻合器进行回-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,术后肠镜随访。结果 2组患者均未发生感染、吻合口瘘、吻合口狭窄或梗阻等并发症。术后肠道排气、排便时间无差异。CAC组CAC于术后8～16 d排出体外。结论应用CAC进行回-结肠吻合较安全可靠,为回-结肠吻合提供一种新的方法。

Objective Nickel-titanium memory-shape alloy compression anastomosis clip （CAC） has been successfully used in small bowel anastomosis and colonic anastomosis. This study was to evaluate the safety and efficacy of CAC in ileocolon anasto- mosis. Methods Twenty patients with ileoeecal junction obstruction induced by radiation enteroeolitis were assigned randomly to a CAC and a control group to undergo anastomosis with either a CAC or a stapler. We compared the two groups in anastomotic complica- tions, first post-operation flatus and bowel movement, and expelling of the clip. Results Such anastomotie complications as infec- tion, leakage and obstruction were found in neither group. The clips were expelled with the stool within 8 - 16 days. The two groups showed similar results in bowel function recovery. Conclusion Nickel-titanium memory-shape alloy CAC is a safe and reliable de- vice for ileocolon anastomosis.
