摘要
To the Editor： The methods for obstruction of colon cancer include emergency surgery or self-expanding metallic stents （SEMSs）. SEMS insertion was shown to be a safe, easy, and effective treatment for left-sided malignant colon obstruction, for palliative treatment or as bridge to resection. The cases reported of SEMS insertion in the colon proximal to the splenic flexure were 〈5% of all studies. The long distances and the tortuosity of the distal bowel make it difficult to advance and position the stent in the target proximal colon, and obstruction of right colon has traditionally been managed by acute operation.
