Thirteen patients with colorectal obstructing tumors were submitted to endoscopic insertion of self-expanding metal stents to restore luminal patency. The procedure was performed entirely under endoscopic control, without using fluoroscopy, during a 1-day hospitalization. The prostheses were correctly placed in 12/13 patients (92%), with no immediate complications. The mean follow-up is 7 months. Ten out of 12 patients (83%) had a permanent restoration of the luminal patency; they experienced no pain, tenesmus or any other discomfort during the follow-up period. In the remaining 2 patients long-term complications occurred and were treated by endoscopy in 1 case, and by surgical resection in the 2nd case. Self-expanding metal stents proved to be safe and effective; the main drawbacks, at present, are the lack of effectiveness of these devices in case of a fistula and their high costs.
13例结直肠梗阻性肿瘤患者接受了内镜下自膨式金属支架置入术以恢复管腔通畅。该手术完全在内镜控制下进行，未使用荧光透视，住院1天。13例患者中有12例（92%）支架放置正确，无即刻并发症。平均随访7个月。12例患者中有10例（83%）管腔通畅得以永久恢复；随访期间他们无疼痛、里急后重或任何其他不适。其余2例出现长期并发症，1例经内镜治疗，另1例经手术切除。自膨式金属支架被证明是安全有效的；目前主要缺点是这些装置在瘘管情况下缺乏有效性以及成本高昂。
