作者旨在估价自膨性金属支架在治疗直结肠肿物继发的结肠梗阻中的应用。作者在已有临床或X线征象的12例急性直结肠梗阻患者体内放入支架。其中7例男性,5例女性,年龄61～88岁,平均患病时间为6天(4～10天)。这些梗阻最早由腹平片诊出,并以钡灌肠法证实梗阻存在,确定其位置。一日证实梗阻为肿物所致,尤其是降结肠和乙状结肠区的梗阻,则考虑应用金属支架治疗,肠道穿孔是本治疗绝对禁忌证。病人术前准备以后,在透视下插入0.038(口寸)角形亲水硬性导丝,并配以7F多功能导
The authors aimed to evaluate the use of self-expanding metal stents in the treatment of colonic obstruction secondary to colorectal mass. The authors placed brackets in 12 patients with acute colonic obstruction who had clinical or X-ray signs. Of these, 7 were males and 5 were females, aged 61-88 years. The average duration of illness was 6 days (4 to 10 days). These obstructions were first diagnosed by abdominal plain film, and barium enema confirmed the presence of obstruction, to determine its location. One day confirmed the obstruction caused by the tumor, especially in the descending colon and sigmoid area obstruction, consider the application of metal stent treatment, intestinal perforation is the absolute contraindication of this treatment. After preoperative preparation, the patient inserted a 0.038 (mm) angled hydrophilic rigid guidewire under fluoroscopy and fitted with a 7F multi-function guide
