结肠镜联合钛夹定位法对结肠肿瘤手术切口选择的作用

目的 探讨肠镜联合钛夹定位法进行结肠肿瘤定位诊断对选择手术切口的指导意义.方法 30例结肠肿瘤患者在术前行结肠镜检查,于肿瘤处使用钛夹进行标记,摄腹部立、平卧位腹平片确定其体表投影部位并进行切口选择.结果本组患者在肠镜下有9例患者（30%）出现定位错误或无法准确判定;联合钛夹定位后,所有患者术前均明确肿瘤部位,以此指导手术切口选择,100%手术切口选择正确,获得良好的术野暴露.结论 肠镜对于结肠肿瘤定位困难,有一定误差率,肠镜联合钛夹标记法进行肿瘤定位,有助于准确定位并选择最佳的手术切口.

Effect of colonoscopy combined with placement of metallic clips on selecting colonic surgery incision

Objective To evaluate the accuracy and value of the placement of metallic clips during colonoscopy in the localization of colorectal cancer and incision selection. Methods A total of 30 patients received metallic clip placement by colonoscopy before operation. Abdominal plain film (supine and upright position) was taken and incision was determined by the projection of clips on the abdominal wall. Results The inaccuracy rate of localization by colonoscopy was 30%(9/30).Colonoscopy combined with the placement of metallic clips achieved an accurate incision rate of 100% (30/30). Conclusions There is a considerable rate of inaccuracy for localization in colonic cancer by colonoscopy. Colonoscopy combined with placement of metallic clips should be considered in order to select a reasonable incision.
