Self-expanding metal stents (SEMS) are successfully being used to acutely relieve obstructing colorectal cancers; yet, their use does not come without complications.
We present a case in which a patient with a recurrent obstructing sigmoid carcinoma underwent colonic stenting for acute decompression. Two months after stent placement, an enterocolic fistula formed from erosion of the upper end of the stent.
An extensive literature review revealed that fistula formation, as a complication of stent placement, is rarely reported. Presentation of the case is followed by a review of complications that may arise following SEMS placement, with a focus on enterocolic fistulae. To our knowledge, this work provides the most extensive review of the subject to date.
SEMS provide an effective, safe, and less invasive option for patients when used in the appropriate clinical context. Further reports of enterocolic fistulae as a complication of SEMS placement are necessary in order to better understand this potential adverse event.
自膨式金属支架（SEMS）已成功用于急性缓解结直肠癌梗阻；然而，其使用并非没有并发症。
我们报告一例复发性乙状结肠癌梗阻患者接受结肠支架置入术以进行急性减压的病例。支架置入两个月后，支架上端侵蚀形成肠结肠瘘。
广泛的文献综述显示，作为支架置入并发症的瘘管形成鲜有报道。病例介绍之后是对SEMS置入后可能出现的并发症的综述，重点是肠结肠瘘。据我们所知，这项工作提供了迄今为止对该主题最全面的综述。
在适当的临床情况下，SEMS为患者提供了一种有效、安全且侵入性较小的选择。为了更好地了解这种潜在的不良事件，有必要进一步报告将肠结肠瘘作为SEMS置入并发症的情况。
