摘　　要：目的评价可回收支架治疗大肠癌术后吻合口狭窄的可行性、安全性及疗效。方法对18例乙状结肠癌、直肠癌术后吻合口良性狭窄患者在X线监视下置入可回收(带回收线)覆膜镍钛合金支架,放置2～4周后,经回收线在透视下将支架取出。结果18例患者18枚支架均一次置入成功,其中3例吻合口瘘成功封堵,15例支架置入后患者肠梗阻症状明显改善,能正常进食及排便。结论可回收覆膜支架对于治疗大肠癌术后吻合口狭窄安全、简便、有效。支架在体内的最佳留置合适时间有待进一步研究。Objective To assess the feasibility, safety and efficacy of retrievable stents in treating postoperative anastomotic stricture in patients after the surgery for rectosigmoid carcinoma. Methods Under fluoroscopic monitoring, covered retrievable expandable nitinol stents were placed in 18 patients with benign postoperative anastomotic stricture after the surgery for rectosigmoid carcinoma. The stents were removed in 2 N 4 weeks after the procedure. Results In all 18 cases the stent implantation was successfully completed in one session. After the procedure, the anastomotic leakage was completely occluded in 3 cases and the symptoms of intestinal obstruction were markedly improved in 15 cases, with their food-taking and stool- passing returning to normal. Conclusion Retrievable stent implantation is a safe, simple and effective technique for the treatment of the postoperative anastomotic stricture in patients after the surgery for rectosigmoid carcinoma. The optimal indwelling time of the stent needs to be further studied, （J Intervent Radiol, 2009, 18： 153-155）
