尼龙绳与钛夹在预防内镜下切除大肠宽蒂息肉术后出血的疗效 和安全性的比较

目的:比较尼龙绳和钛夹在预防大肠宽蒂息肉切除后出血的疗效和安全性的比较.方法:从2005年1月至2011年9月连续选择155例患大肠宽蒂息肉和有蒂且顶部直径大于10mm息内的患者.随机分为3组.A组(53例),将尼龙绳套扎息肉的基底部,然后使用常规的套圈器进行息肉电切术.B组(52例),使用常规的套圈器进行息肉电切术,然后残端使用钛夹缝合.C组(50例),使用常规的套圈器进行息肉电切术.结果:所有息肉均成功摘除.A组和B组1例出血；C组5例出血,其中1例需要手术干预.结论:大肠宽蒂息肉常规圈套器进行息肉电切术具有较大的出血风险；尼龙绳和钛夹对内镜下切除大肠宽蒂息肉术后出血具有良好的预防作用.

Efficacy and Safety of Endoloop and Titanium Clips in Preventing Hemorrhage of Endoscopy for Colorectal Wide-Pedicle Polyps Removal

Objective: To evaluate the efficacy and safety of endoloop and titanium clips in preventing hemorrhage of endoscopy for colorectal polyps.Methods: Total 155 cases of colorectal polyps with wide-pedicle or the diameter of polyps being larger than 10mm were conducted from January 2005 to September 2011.These patients were divided into 3 groups.53 basals of the polyps(endoloop group) were nipped with endoloop before high-frequency electrosection.52 basals of the polyps(Titanium clip group) were excised with high-frequency electrosection before nipping with Titanium clips.50 basals of the polyps(control group) were conducted normal high-frequency electrosection.Results: All cases of heterotopic pancreas were resected successfully.1 case had bleeding in endoloop group and so in Titanium clip group;while 5 cases had bleeding in control group.1 case needed surgical intervention in control group.Conclusion: Endoscopy for colorectal wide-pedicle polyps removal were easy bleeding with normal highfrequency electrosection.Endoloop and titanium clips were effective and safe method in preventing hemorrhage of endoscopy for colorectal Wide-Pedicle polyps removal.
