暂时性金属内支架治疗结肠梗阻和对手术方式的影响

目的探讨在X线透视下经内镜引导置入暂时性金属内支架缓解结肠梗阻的方法和临床应用价值。方法33例结、直肠癌引起肠梗阻的患者，在X透视下经内镜引导在梗阻部位行暂时性金属内支架置入术。结果27例成功置入金属内支架后24～48h肠梗阻症状缓解，经肠道准备后均作了选择性Ⅰ期结肠癌切除吻合术。支架置入成功率81．8％。结论暂时性金属内支架可有效的缓解结、直肠癌引起的梗阻，在X透视下经内镜引导能提高支架置入成功率从而使梗阻患者的结肠癌能得到Ⅰ期切除结肠吻合。

Temporary metal internal stent dilation for colorectal obstruction and effect on operation methods

Objective To explore the methods and clinical value of temporary internal metal stent through endoscopy under X ray control for treating patients with malignant colorectal obstruction. Methods 27 patients with malignant colorectal obstruction were treated by temporary metallic internal stent placement via endoscopy under the X ray guidance. Results 27 patients with colorectal obstruction symptoms were all got rid of the trouble within 48 hours after the stent placement. Selective stage I colorectal cancer resection and anastomosis were performed after bowel preparation. Conclusions Metallic internal stent placement can loosen the colorectal obstructive symptoms with higher successful rate via endoscopy under X ray control and furthermore for promotion of stage I coeloretal cancer resection and anastomosis.
