Self-expandable metal stents (SEMS) are used to relieve malignant luminal obstruction throughout the gastrointestinal tract. Colonic SEMS are used most often for palliation of obstruction in nonoperative candidates or in patients with advanced disease. The other indication for colonic stent placement is as a preoperative modality for the relief of acute obstruction so that resection can be done on an elective basis after stabilization of the acute illness and bowel preparation. For both of these indications, the goal is avoidance of a temporary or permanent ostomy. In this manuscript the supporting data for each of these indications will be reviewed.
自膨式金属支架（SEMS）用于缓解整个胃肠道的恶性腔道阻塞。结肠 SEMS 最常用于非手术候选者或晚期疾病患者的梗阻缓解。结肠支架放置的另一个适应证是作为急性梗阻缓解的术前手段，以便在急性疾病稳定和肠道准备后择期进行切除。对于这两种适应证，目标是避免临时或永久性造口。在本文中，将回顾这两种适应证的每项适应证的支持数据。
